I've been waiting to hear back concerning my motor/speed controller. I placed the order on 4/25 and no word on availability or ship date.
Patience is not a strong point with me lately so I just ordered a 2212-10, 3 APC 10x4.7 propellers, and an 18A ESC from BP Hobbies. Worst case is I wind up with 2 motors - maybe I'll wind up with two planes. It sounds like plenty of things get broken when flying Towels so in the long run, spare parts are probably a good thing. Besides, my friend Michael seemed mighty interested while reading the Make article this past weekend. Maybe he could use the spare motor (if it shows up).
