New direction, away from inexpensive, medium power, beginner frames, in to mid priced high power, heavy lifters, medium light frame…
Sorry no video yet.

I think I could get that cost down by $250, by buying in quantity, and swapping parts (particularly motors, escs, and carbon fiber).
My goal would be to sell a few then buy a maker bot, and make all the wood platforms out of abs. Then start getting funky with designs.
