Some EDF models has intake and/cheater well above the underside of the planes, such as A-10 Warthog, F-117 Nighthawk, A-4 Skyhawk, He-162, BD-5, etc. If one wants to avoid the dreaded handlaunch of such rc model, it is possible to install wheels on the underside of the plane and make the takeoff from concrete.

Material:
  • short piano wire (size depending on the model weight). The diameter of the wire should be just a bit smaller than the diameter of wheel axial. Too small diameter of the wire might cause too much play of the wheel and difficult to keeping the model tracking straight during takeoff.
  • plastic wheels or foam wheels (again depending on the weight)
  • pieces of plastic (I prefer pieces from either milk bottle or detergent bottle, for light weight to heavy duty models)
  • plastic or metal washer (prop adaptors that comes with many plane propellors are good for spacing), this is optional

Procedure: for each wheel to be installed
  • Cut two rectangular shape pieces of plastic, sand with <100 grain sanding paper/block for later gluing. Make sure the plastic pieces slightly larger than the diameter of the wheel to be installed, so that wheel can freely move
  • Drill holes on the plastic pieces that fits the piano wire
  • Cut out hole in the fuse/wing that is slightly smaller than the rectangular plastic piece. Assuming we are working on the foam, the slightly larger plastic piece will fit tightly inside the hole. Make sure the hole large enough to fit the plastic/wheel assembly.
