Custom Mini Flying Wing (folding)

Dr Dankeinspank has been in the lab creating a pocket rocket… no it’s bigger than that. It’s a backpack rocket.

Sometimes the only way to get exactly what you want is to create it.


The objective with this build was to have a small backpack-able glider that is also durable.  Bonus if it can use a Hubsan battery and some other goods that are hording up the shop.  A brushless motor may eventually get integrated but for now a glider will do just fine.  Sitting on a sandy bluff gliding in the ocean breeze is a good way to invest time.

It started out as a chunk of purple insulation foam (extruded polystyrene) from Home Depot.  It was then cut with precision to an airfoil cross section with a CNC hot wire cutter.  A fiberglass spar (lengthwise stiffener) was added for strength and a small piece of plywood was glued on the bottom to provide a sturdy mounting point for the hinges.  The Hinges are RC airplane control surface hinges for a much larger plane.  Putting the electronics in the front is usually a good idea so that ballast weights don’t have to be added to balance the plane later.  One of the most important aspects of getting a plane to fly is having the center of gravity in the correct place especially for a flying wing.  With a straight wing the center of gravity will typically be 15-20% back from the leading edge of the wing. With a tapered and swept wing (like we have) it is a little more tricky; we will have to get into that at some other point.


  • 2 x 6 gram servos (nothing fancy just cheapos)
  • 1 x Radio Receiver
  • 1 x 2.4 Ghz Radio Transmitter
  • 1 x Hubsan 380 mAh Battery

Still have some work to do.  Future plans Include:

  1. Drill lightening holes
  2. Cover wing with cellophane and packaging tape
  3. Attach winglets (vertical stabilizers)
  4. Attach elevons (control surfaces)
  5. Fabricate a nose cone/fairing
  6. Balance plane (critical for stability)
  7. Crash
  8. Rebuild
