SwitchBlade 90


A 90 mm EDF SportJet with a 1200 mm wingspan is the newest and most advanced model by Don Wright, our experienced 3DLabGang contributor. His models are designed from scratch, without the constraints of real aeroplanes to allow for the best possible performance.

You  will get:

  • STL files
  • Simplify3D Factory files
  • Basic presliced Gcodes for Prusa i3 compatible printers
  • Decals, build instructions

You will need:

  • FDM printer with a 200x200x200 mm build volume
  • @1.2 kg of PolyLight LW-PLA and @0.4 kg of PolyAir PLA
  • 90 mm EDF (Freewing or Eflite)
  • 130A ESC
  • 6S 5000 mAh Li-Po battery
  • Carbon tubes and rods (see the instructions)
  • Landing gear (see the instructions)
  • 7x 17g servos and 2x 9g servos
  • Pushrods, and other jewellery (see the instructions)
  • Maglite landing lights

Product Description

The SwitchBlade 90 is a culmination of much research and incorporates the best of
the best, – proven airfoils, wing loading, access and most of all, the ability to print your
own Sport Jet. You’ll be rewarded with a predictable tracking airframe that cuts cleanly
through the air. An airframe that is just the right weight to keep you flying when other
guys are packing up due to wind.

  • 1
    Creating process of digital modelling

    Extensive hi-tech 3d structural reinforcement resulting in solid yet lightweight airframe thanks to additive 3Dprinting technology

  • 2
    Printing and testing

    Each plane has been thoroughly tested to find ideal shape and best possible inner structure
