Specialized race frame kit.

  • Strengthened arm attachment compared to the ARX-5R launch frame – weak points are eliminated
  • Revolutionary arm design that uses a patent pending method that optimizes material use. This allows a smaller cross section, freer flowing air stream and less obstructed thrust cone which leads to several performance improvements:
    • Quicker acceleration
    • Faster top end speeds
    • Quieter due to less pressure change across the prop disk
    • Less material use reduces moment of inertia
  • Based off the 202mph XLR-1 frame project (Guinness record acceptance still under review – review period takes a lot looooonger for poor people)
  • Convert from stretch-x to true-x in about 1 minute
  • Can accommodate up to 8S battery packs (may require larger size o-rings which I will offer soon)
  • Uses 3 o-rings as straps to hold in the battery and to hold the FPV camera mount in place
  • Protective braided mesh tubing included in the kit to protect FPV camera wires
  • Includes all aluminum hardware
  • 41.7g with 5″ arms, 43.6g with 6″ arms including hardware and o-ring battery straps
  • The stack has virtually unlimited room and easy to work on
  • There is room between the center arm plates for a 20×20 FC or 20×20 4 in 1 ESC. windows are provided for USB/wiring access
  • Designed for 20mm wide FPV cameras, although spacers could be used to increase this distance
