First finished model - flight:


For your Prandtl D wing, if you take it up real high and shut your motor off, what kind of a max glide do you get into a low wind? Set rates low.

Also, have you had any luck of hitting a good thermal and try motor off to see what happens? Would be very interesting.

Assembled the DVa's power system this eve and put it on the test bench. 3S battery, 40a ESC, 1000kv motor, 12x5 wooden prop.

Throttled up to about two thirds throttle and held for one minute. The RPM stayed pretty consistent, but the motor Bell is too hot to hold onto for more than four seconds and it's making the standard 'overheating electronics l' smell. I was worried I might be asking too much of it. Trouble is, I kinda designed the formers and stuff around this motor. Here's hoping an 800kv motor isn't too much bigger.

What are the specs of the motor you have? And what are you looking to acquire?

All I have for this is that it is the Racestar BR2212 1000kv. I think I chucked the box it came in and the leaflet with it. I've ordered an Ares 750kv (800kv was surprisingly hard to get from the UK, would've had to wait for them to come from either China or US), which should arrive Monday.
