The best just got better!!
New iPAs set up: an even more powerful rear-mounted motor (PA Thrust 60 Revo 24 Poles), precision super torque servos (NXT-100HV) and Factory Pre-installed LEDs!
This tremendous upgrade in the setup expands the ADXL flight envelope and gives it a whole new style of flying never seen before in the Addiction XL.
This phenomenal slow 3D flyer, is NOW capable of higher energy maneuvers! The V2 excels in faster snap rolls, more precise point rolls, high speed knife edge circles and even tighter knife edge spins and blenders.
The Addiction series is the first balsa/built up planes to feature factory pre-installed lights!
The bright-leds are not seen from the outside so the plane can be flown during the day and INTO the night! When your flying-buddies lose sight of their planes and call it a day – you get to keep flying and have the field all for yourself…
Addiction XL V2 features:
- Unique aerodynamic design
- PA most up-to-date innovative FiberFusion techniques – more solid than ever!
- Custom-made new airfoils further expand its flight envelope
- More powerful iPAs set up – 24 poles Thrust 60 Revo motor (rear mounted with CF X mount) combined with NXT100-HV digital metal gear servos for a completely new level of performance, never seen in the Addiction XL before, allowing much faster flying-speed for high energy and precision flying, without compromising the phenomenal slow 3D capabilities that the ADXL is known for.
- Factory-ready for night flying – extending your flying hours into the best time of the day, when temperature and wind drops.
- Included light harness custom made, pre-soldered and ready to use.
- New awesome updated color scheme and checkers on bottom wing as so many of our fans requested, for better visibility.
Despite being a 3D plane in every aspect, it is extremely stable and precise – capable of impressive precision aerobatics maneuvers with a feel much like a 150cc airplane.
Being built using finest grade material, all cut by state-of-the-art laser and CNC machines and utilizing the very latest PA FiberFusion® building techniques, the ADXL is incredibly lightweight and rigid. In fact it is by far the lightest fully-constructed plane in its size.
Don’t be misled by the wing span – this model is HUGE with a wing area of 1,055 sq. inches (similar wing area of most 70” class aerobatic models on the market today).
The size of this plane makes a huge difference in the flying capabilities and flight envelope and especially at its wind handling capability and stability. Of the Addiction series, the XL handles the wind better and is easiest to see due to its size, yet like its smaller siblings – it is extremely rewarding to fly!
iPAs Set Up
The Addiction XL’s lightweight and unique aerodynamic design means its iPAs set up (for ultimate hardcore 3D performance) is an economic Thrust 60 Revo 24 pole/Quantum 70HV combo with two 2200mAh / 2600 mah 3S packs in series, or one similar capacity 6S pack*. This means you get to fly this massive plane at a very minimal investment compared to other models of its size – then again – there really is nothing like it.
*If you plan on using the factory built-in night lights – use two batteries and not a single 6S for easier set up.
The NXT 100HV super high torque servos are precise and agile, giving you confidence to execute new maneuvers. (They make a real change in the plane’s performance when comparing to the ADXL v1).
Note: If you own a Thrust 50 and wish to have it installed on the Addiction XL V2 – simply specify that you require V1 motor mount in your kit.
Up until the Addiction XL – when you thought of a 3D dedicated airframe, automatically you would not expect it to track well or perform accurately.
The Addiction XL will surprise you as it tracks better than any other Addiction or other 3D plane of its size. The generous tail section means awesome tail authority and the ADXL advanced aerodynamic design allows you to do incredible elevators, knife edge loops, high alpha knife edge, rock steady harriers, the easiest and most impressive rolling harriers, and yet when you go to low rates, its capable of the most beautiful point rolls, and rolling circles. The ADXL is even capable of tricks like one roll circles and loops and beautiful slow rolls that you can take to the length of your flying field! Engineered for precision flying, the ADXL is a very neutral airframe – you will find zero coupling and no mixing required for precision flying. No CG adjustment required for switching between precision and 3D flying either!
The ADXL does beautiful fast knife edge circles, and even knife edge elevators and knife edge waterfalls! Things other planes are not capable of. The flight envelope will keep expanding as you get more and more familiar with the plane, and being a slow flying plane will make new manoeuvers easy to experiment and develop – which guarantees to improve your 3D and precision flying skills.
The ADXL V2 is NOW capable of higher energy maneuvers! The V2 excels in faster snap rolls, more precise point rolls, high speed knife edge circles and even tighter knife edge spins and blenders.
The ADXL power set up is very responsive allowing you to get out of get out of the most difficult situations with ease. This, combined with its predictability and very slow flying capability, makes it a perfect choice for entering into 3D or you can just enjoy it as an accurate sport plane and build your confidence. Yet in the hands of an advanced 3D pilot – the ground is truly the limit!
The word best describes this plane is FUN and you’ll impress anyone at the flying field because the ADXL makes it look so easy!
We said this before: “3D is challenging and fun, and with the right aircraft it is within the grasp of anyone regardless of experience or flying skill!” The Addiction XL is all about that!

What is iPAs? – Integrated Performance Airframe-Drive System
NO COMPROMISES, NO MODS, NO HASSLE
THIS IS THE REAL DEAL: PERFORMANCE OUT OF BOX
WHAT YOU SEE IN OUR VIDEOS IS WHAT YOU GET WITH iPAs
Unlike glow aircraft where it is mostly a matter of bolting on a specific size engine, the options for electric flight gear are simply overwhelming and matching electric gear to an airframe is a complex task for the average modeler and quite often can be very confusing.
Most manufacturers direct their customers to acquire a “compatible” motor and ESC or at best offer a “Combo” package that comprises of an off-the-shelf motor and ESC that would, in theory “fit” within the model’s power requirements.
Surveys we conducted showed that each and every EP models flyer has experienced at least one if not more of the following problems:
- • Unpredictable handling problems caused by reduced wing loading due to oversized motors or battery packs or ancillary gear.
- • Overheating or unwanted ESC cut outs due to over propping or undersized motors
- • Handling problems due to drastic shift in CG and overall weight distribution.
- • Unacceptable flight duration due to inefficient “hot” motors or undersized packs
- • Airframe structural failure due to increased aerodynamic loads caused by oversized drives and packs.
- • Overheating and swelling of battery packs caused by serious drive mismatch.
- • Less than optimum motor performance due to ESC incompatibility.
- • Crashes as a result of servo gear failures caused by excessive loads on the control surfaces or exceeding the maximum airspeed limits.
- • A huge disparity in flight performance observed in the promotional videos against actual aircraft.
- • Premature Motors, ESC and Battery failures or performance degradation over time due to mismatch setup.
- • Gear does not properly fit the airframe and requires modification.
We do not believe modelers should have to live with compromises in flight performances.
Through hundreds of hours of flight testing our airframe designs, we have established that there is a direct correlation between airframe and drive system, which influences the desired aerodynamic performance. This means that airframes and drives should not be treated as independent items, but as one integrated system.
Due to the extreme lengths taken in the design of the airframe, and the unprecedented flight testing period to finally achieve the desired aerodynamic characteristics, we felt a complete solution for this model is necessary. As a result, we have developed our iPAs, PA Integrated Performance Airframe-Drive System.
Each iPAs component has been carefully selected, tested individually and on the airframe itself. Any impacts on the overall flight performance and aerodynamic characteristics have been identified and addressed to ensure that all iPAs components interact in full synergy, as an integrated flight system within the constraints of the design specifications. Each component has then been further refined. The result achieved is a perfectly matched setup, successfully meeting the desired performance criteria.
For the first time, flyers have the unique opportunity to experience the exact aerodynamic performance as envisaged by our chief designer and team of test pilots minus all the guess work and unnecessary expense.
Just got my AMR 60. I must say what incredible piece kit this really is. Cant wait to get it in the air. I also have the Addiction XL and still to this day have not found a aircraft that fly’s as good. Keep up the good work and I look forward to seeing some new models in the future.
Matt Jones, UK
My Addiction XL has arrived this week. I have unpacked everything and I must say packaging is second to none. Futhermore all parts are in absolutely excellent condition, no warping, no nicks, no dents, no nothing. Just flawless. All parts I have ordered in addition were very carefully placed and taped into the box. Taking such care despite having a huge order backlog to process is nothing short of top notch customer service. I am very proud to have bought a plane of such a great company. Many thanks again to you and the whole team. Can’t wait to start the build and get it in the air.
You know why it’s called an Addiction …. ‘cos it’s freaking ADDICTING flying the AddictionXL
Great flying planes. Had 2 ADXL’S so far and want another one.
I’ve flown my Addiction XL several times now and it is truly the best flying plane I’ve ever owned
My ADXL is an amazing 3D flyer…making ME better!
Just received my Addy XL V2 and I must say I am truly impressed! The difference between this plane and the Addy XL I purchased a couple years back is remarkable! After going over every inch of my V2, I can’t find a sign of a peel anywhere. Drum tight and control surface edges ruler straight! All dry fittings seem to be right on. And I love this White scheme. My other Addy XL is red and blue as my fly”n buddies have red,green,purple,etc. So this one is definitely going to stand out. I’m enjoying this build so much, I may milk it for a couple of weeks until it’s purfect!!!! There is nothing out that flies like an Addy. It does’nt tumble like an Edge or an Extra but then…….let’s see your Edge do this!!!!!!!! So……I’m a happy guy and a PA cust. forever! Good work PA!
My 9yo son, David, started with an Addiction XL. He has a TON of flights on it. It is so big, easy to see, and forgiving it is difficult to argue against. Just slow the rates down.
I just buddy-boxed his first 20 flights or so. He hasn’t had a lick of trouble flying it.
The new addiction XL V2 has really helped me smooth out my flying and make my flights look more coordinated. When I first flew it, something clicked in my head and I was able to get lower than I have in the past and more precise than I have in the past. The new thrust 60 and nxt 100s have definitely woken up this airframe to allow it do some higher energy manuvers as well.
I really like the Addiction XL and a big thumbs up on the quality of the plane.
Well today was my maiden of my addy xl. 3 clicks of down and she was level. Wind was calm. Absolutely a marvel to fly. So smooooooothe. It will take getting used to something so agile. Until now I’ve been flying a 60 cc aeroworks extra 260 at 18 pounds. This is so different. A job well done on the design. Thank you all for all your help. Look forward to many years of flight time with my xl!
I got everything completed and flew the plane for the first time today. Worked perfectly, and, my goodness, does it do amazing 3D!!!
Had my maiden today, I love this plane fly’s like a dream. Great job PA.
rogersrick123 @ RCGroups
My XL arrived Today. A beauty. Great packaging and everything in perfect shape.Amazing engineering job, all these interlocking parts, balsa inserts with correct grain direction, carbon where needed – it crossed my mind that I should buy another one, strip down covering and keep it as a sculpture – it really is that good.
faldomak @ RCGroups
All I can say is WOW! Madiened the XL yesterday. Installed the 2200 batteries as indicated. Launched, and did not add ANY trim to any surface! Perfectly stable! The field was in awe on just how slow this airplane will fly around the field! Flat spins just like we saw the PA pilot perform here. In fact, I like it so much, I went out again this morning and did again! Charging the batteries again to repeat the process tomorrow. The wind was zero this AM (fog on the field in fact), so I was able to fly it so slow with no hands on controls. Flew my XL again today, zero wind at 8:00 AM, and warm, now 80 degrees. I’m thoroughly impressed, as this is a smooth machine, elegant really. And, into a breeze yesterday late morning, will fly at walking speed! Not kidding!
I have already placed my order for the XXL, which will be 71″, LOL… (Hope they are listening!)
four stroke pwr @ RCGroups
I’ve had a few flights on my XL, and she has plenty of power to pull out. Use the 16×6 prop, way better for slow 3D. I really like this plane, you don’t realize how big it is until you go back to the X, it’s like day and night. Once I found the CG sweet spot, she locks into a hover perfectly. I took some expo off from the manuals suggestions, I was using way to much stick to hold her steady. I’m at 50% elevator, 50%ailerons, and 30% on the rudder using a JR 11X.
Rudder was the biggest improvement, I find it harder to keep the tail steady in a hover if I need to move the stick to far over while playing with the throttle. I have the 3DHS 74 Edge 540 and it’s a great 3D flyer, but the XL is way easier to fly 3D, no bad habits and beautiful rudder control with the wing hardly dropping.
You are so right on Mr Kamikaze, the XL is a nice improvement over the X, just like the X was over the original Addiction. This is the best 3D plane I’ve ever flown.
rogersrick123 @ RCGroups
Holy Cow!!! I just maidened my Addy XL and it’s craZZZZy!
The Addy XL is the same step up from the Addy X as the Addy X is from the original Addy. We know the original Addy is a great 3der so imagine how good this Addy XL is!!!
I videoed the maiden and you will not believe it when you see it. On low rates it’s big and precise and smooth, on high rates it… Well it’s stupid slow and stable. And sooo easy to do it with as well.
Shaun, my hat’s off to you man. You are a designer with vision and an amazing comittment to giving us all the opportunity to fly planes like this.
Get one of these guys, take it to your local flying patch and watch the jaws drop!!!
This plane was enough to pull me back into the hobby. I hadn’t flown but a couple times over the last 10 years and was browsing RCgroups and came across the ADXL and was hooked! I had a few Su-do-kois(SP) including a couple of the giant ones years back and loved them. Some may be too young to remember them but they were a profile with lots of wing. I ordered an ADXL last week and it should be shipped tomorrow! Can’t wait!
jwrdn @ RCGroups
Test flight complete! Extremely happy. Buy one of these only if you like Floaty 3d planes that fly well!!!
MICKEL @ RCGroups
Hello P.A. I would like to thank all of you Cheryl, Jim and Jerry and anyone else who works at P.A. For the customer service, you are so nice and accommodating. Very professional but like talking to a friend. Wanted to thank the guys for there shipping and packing well the packing is the best I have dealt with on-line, they do the little thing to keep your products safe like taping props to a piece of cardboard. Owe yeah they make Great planes to. Thanks again P.A. Richard R.
PA product is outstanding good and solid planes! (I have 4 Pa planes in my collection, and i’m very satisfied with their performance!)
Paul Gunnar Strand, Norway
I ran six sets of packs through my Addy XL this morning.. what an incredible experience. Love this plane!
four stroke pwr @ RCGroups
Hi All, I just received my ADXL – what a piece of Art… – I am putting it together for a photo shoot
Thank you for providing these great Precision Aerobatics airplanes to the world! Extremeflight, Pilot-Rc, Eflite, Aeroworks, Great Planes, Hangar 9 could go to bed and sleep, compared with the PA machines! I have never seen or flown a electric balsa/carbon plane with this kind of light weight and extreme durability as the PA planes! I’m on my third PA bird now (there will be a fourth), and the best so far. The Extra MX is amazing! It looks great and the performance is fantastic! The only thing I wish you could do to the Extra mx is to add carbonfiber in the front of the glasfiber cowling as you already have in the back, it cracks up really easily.
Again! The best electric flyng machine I’ve ever had.
To everyone PA team – Thanks!
Robin W. Karlsen
The lightweight strength in every Precision Aerobatics plane gives you the feeling that you can do anything. My Addiction XL floats like nothing else I have experienced. From the very first flight, I have been impressed with how stable and responsive it flies. I have other planes in my inventory – but I can always count on an enjoyable flight when I grab my Precision Aerobatics – Addiction XL!
Absolutely without a doubt is the design of the PA airplanes. I have a Addiction and Addiction XL on the bench now being built, they are a joy to build
I love my Addition XL, because it is the best flying plane in my fleet.
PA planes make me look like a better pilot. I’ve had many different PA planes over the years and I love them all. My favorite right now is the Addiction XL.
I have the regular and XL addictions and I love them both. Crisp handling, light wingloading, sturdy construction. Thanks PA, the addictions ROCK!
I loved how my Adiction XL went togather. flys great. I just need to be a better pilot. I also got the Bandit before it went out of stock in the US. Lucky me.
Paul J Bajnoczy
Building a Addiction and Addiction XL at the same time, what crazy beautiful airplanes, thanks PA
My husband has an addiction X and an XL and a Bandit. He absolutely loves them !! The best planes ever! Makes me a weekend flying widow … lol
I started my addiction with an extra 260. next i saw the addiction in a video and thought wow what an ugly plane. when i watched the video i bought one and then another. then the addy x came along . have had 6 of them. the addy xl have had 2 so far. also along the way i have had an extra mx a katana mx an ultimate and an electric shock.does anyone know of a group that can help with this sort of addiction? I just ordered a new Addy X today
I will say the addiction was my very first balsa and pretty much my first plane. The stability of PA planes are amazing it has taught me how to fly 3d the guys at the field do not believe me when I tell them how long I have flown. I really didn’t want to come out and tell no one but the truth be known it is because of the planes I flew. Addiction, 2x X’s and then on to the XL and now the XR is ready to maiden. One of my daughter’s now is flying my first addiction I purchased. So with that said I’m very thankful for the planes that I have from PA not only bringing my daughter’s and I closer together but involving them in a lifelong skill and not on the street looking for trouble like I see with many kids today. So with a new addiction my youngest daughter would be thankful but even without I may just have to cut one of my X
I own an Addiction XL and an Ultimate AMR. Both planes satysfied me from the start. The pre-assembled parts are perfectly manufactured and the final built up you have to do at home is arranged logical and using the manual very easy practicable. I never got in trouble getting any spare parts (thanks to my local PA provider braekman.de) whereupon it instead of the detailed construktion of PA planes often was no problem to fix minor injury even with my low skills in building. First it was a hobby, with PA it became passion, that means this brand made me become a fan in a way I actually only knew from rock stars!
I had my 1st flights with my addiction xl and all I can say is wow ,wow,wow I love this plane and can see why you named it addiction. Thanks for a great product.
I am now flying the Addiction XL exclusively and love the plane. When I am doing any maneuvers the plane always holds its position, especially when in a hard climb and near a stall the plane will not lose position and stay put. All my other planes wanted to pull to the left. I love the saying on the Addiction XL(The Ground Is The Limit!) . It is so true. I hope you got a patent on this. Whenever I fly I always remember this saying. I guess it keeps me grounded. I love this plane.
The planes you guys design, build, and sell are above anything I have ever flown……..of our fleet of almost 40 planes…the PAs are the only ones getting an flying time…..as a matter of fact based on my timer on my radio, my Katana has flow from Ohio to California and all the way back to Denver if I use a 30 mph rate of travel……..
You are welcome to post this in your testimonials section……
You Sincerely Grateful Customers: Scott and Scott Jr. Waite………
Scott and Scott Jr. Waite
I flew my new Addiction XL today, first time. Instructor was telling everyone how great my first landing was with it. I rolled it upside down first flight and it needed no down elevator. An awesome plane.
“This plane is the best airplane I’ve ever flown. Just so you know. It’s all I fly anymore.
Thank you, “
It is a one of a kind design for sure. And it’s huge.
Incredible (not that you need my complements).
THANKS FOR THE BEST FLYING PLANE IN THE WORLD!!!! THANKS – RCLARRY
I received an Addiction XL from my girlfriend for Christmas and first thing I have to say is the quality of this model is amazing
Thanks so much.
Shipping was timely and customer service was very good with my recent purchases with PA.
jevery @ RCGroups
Wanted to thank everybody at Precision Aerobatics for getting my order out so fast and for the customer service that is great. I added to my order twice and the good people at PA dealt with me with in a patient and pleasant manner. The packing is top notch one of the best in the industry. Thanks again for the great experience.
Dear Lady: this is just a simple letter of praise for Cheryl Widner at P.A. U.S.A. – I recently made an order of two electric RC planes and made a mistake in doing so!
Cheryl called me to verify this is what I wanted (it was not) she helped me get this order right and answered all of my questions and needs in such a courteous and professional manner, I felt this letter was in order! Not only do you sell the best model aircraft on the planet, you also have top notch employees and support crew like Cheryl !
Dennis A. Hobson
Many companies have support for e-mail questions. However, very few answer in a timely, accurate fashion as you did.
This tells me that PA understands the value of good customer service. I will definitely purchase my next aerobatics aircraft from PA.
Thanks for getting my Addiction XL out so quickly! Ordered on Wednesday and delivered Friday. I appreciate the great service
Thank you for your call back, and the time you spent with me today. If this plane fly as well as your customer service this will be my favorite plane. Customer service any more seems to lack politeness, concern and urgency. This is not the case with you are your company. This Hobby is my fun and release I appreciate your friendliness politeness concern and urgency. Thanks again and look forward to meeting you some day.
Thanks so much! The service is just as brilliant as the plane it self!
Videos below are showing V1 set up. Addiction XL V2 videos are coming soon
In this Episode of PA Builds Hans’ covers servo installation and the building of both types of linkages found on PA planes.
In Episode 3 of PA Builds Hans Kahlert continues explaining the propert techniques and methods of construction your PA ARF. Topics cover include: Installation of the tail, motorbox, and the pull-pull system
Hans Kahlert continues the build video series with Episode 4.
Topics covered include:
Landing gear assembly
Installation of the Motor, ESC, and air scoops
Cowling alignment and mounting
Installation of the Optional CF Vortex Generators
Hans Kahlert demonstrates the basics for a good radio setup as well as the methods to properly balance your model and its prop
PA Team Pilot Hans Kahlert continues along the “Builds” series with a special episode covering the proper techniques for soldering electrical components of your model. These methods are applicable for all soldering procedures including servo extensions and battery connectors.
PA recently upgraded the servos that are included with the iPAs packages with better performance in mind. The NXT High Voltage servos are far superior to the Hitec servos that were previously supplied with the models. They are effectively improving the plane performance and as such we felt that its not a good idea to hold on the upgrade of the servos in the iPAs package just because of the servo bays of the models that were just produced was already cut for Hitec. Instead we supply the model with spacers that allow the user to modify the servo bay to fit the NXT servos.
In this video Shaun Vanunu, Designer of PA models is showing how these spacers should be installed
Vox 16×7: This prop is a must-have with the ADXL and is included in our iPAs Power package. Due to the large size of the ADXL V2 (more drag), this prop is an excellent match with overall performance for fast aerobatics and 3D. The larger diameter and extra punch make it a better choice in a windier day. Great flight speed, faster roll rate, tighter tumbles and waterfalls with the Thrust 60 Revo. The ADXL V2 has a very wide flight envelope from precision aerobatics maneuvers to very slow and easy 3D. The extra output thrust this prop produces is therefore essential, especially in sustaining the flight speed during the transition between maneuvers so you don’t lose much of the energy. The Larger prop diameter generates better propwash for 3D flying.
Vox 15×8: Provides excellent power for sport flying, 3D and precision flying, and yet is still very capable of high energy maneuvers. It offers a slightly faster top speed compared to the 16×7, but offers an easier to manage throttle response. It also offers longer flight duration. NOTE: The smaller prop diameter generates slightly less propwash for slow 3D, however offers slightly faster spool up for easy exits out of tumbles, blenders and knife edge spins.
Warning: Plastic APC “E” propellers of equivalent sizes are NOT recommended for any of the PA planes as they generate a lot of vibrations being out of balance. They also flex and will draw much higher amps compared to the Vox props at the same sizes being less efficient. Using them instead of the recommended Vox propellers can lead to a motorbox failure!!
