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.

Electronics

  • 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

Lost Screws?

Lose your screws while dissembling your Quadcopter?
Chances are they are stuck to one of the motors because of the magnets.

Still can’t find em don’t worry Cali Bros have them for cheap here.

Battery Strap Sticker

Dr. Dankeinspank has probably charged about 10 Million batteries and he’s tired of pulling them out by yanking on the wires.  Shoot he’s probably broken one or two of em cause he was so stoked for his next flight. We can’t have the Dr. missing any sorties with the Bros cause he has a downed bird.  Cali Bros Battery Strap Sticker thing does the trick. Just wrap it around your battery. Now you can tug on the sticker instead of the battery wires.  You don’t have to put it on your battery, but you should (stickers come free with battery purchases or you can buy a bundle).
