Everything you need to get your Katana 52 / XR-52 V2 flying if you already have the airframe!

Through hundreds of hours of flight testing our airframe designs, we have established that there is a direct correlation between the airframe and drive system and one affects the other with consequences to the desired aerodynamic performance.

That meant airframes and drives should not be treated as individual items isolation but as one system. As a result we have developed our iPAs, PA Integrated Performance Airframe-Drive System allowing you to experience the exact aerodynamic performance as envisaged by our chief designer and team of test pilots minus all the guess work and unnecessary expenses.

The Xtreme minus airframe package includes

  • PA Thrust® 45R Back Mounted outrunner motor with RotorKool® Technology
  • PA Quantum 45A Evo High performance Programmable ESC with HV Selectable voltage SBEC (6.0 – 7.4v – 8.0v)
  • German made CNC machined precision prop adapter. We decided to include this adapter instead of common prop adapters usually bundled with motor accessories to avoid performance robbing vibrations and motor mount structural damage.
  • PA Gen2 LiPo 2600mAh 11.1V or 14.8V  30-60C
  • Nexatec NXT-180HV servos – 4pcs (NEW High end, best in class! Torque monster, High Speed, and Ultra Precision / FULLY CNC machined)
  • Thin gauge twisted light extension lead (made in the same German factory as our giant scale airplanes HD leads). Due to its fine high quality strings it is extremely flexible preventing RF noises and features low internal resistance.
  • Set of 4 Carbon Fiber extended servo arms specifically designed to achieve the desired linkage geometry for full control surface movement. Note: these are different to the micro servo arms sold with other.
  • Low resistance Original Amass XT60 Plugs and Gold plated bullet connectors for the best electrical connection and power delivery to the drive.
  • Vox 12 x 7 or 13 x 5 (4s) / 15×6 or 14×8 (3s) Wooden Propeller

NOTE: Spinner and Vortex generators are not included in this package.
