Is this too big?
I ordered this motor:
http://cgi.ebay.com/ws/eBayISAPI.dll...m=290666938196

which I think it is the same motor as above.

I received them and they weigh about 2 grams.
They are about 2/3 the size of the 929 motors.
With a 4 1/2" prop at 3 volts I get 2 grams thrust at 2200 RPM.
With a 4 1/2" prop at 4 volts I get 3 grams of thrust at 2500 RPM.
With a 4 1/2" prop at 7 volts I get 5 grams of thrust at 3200 RPM.

With a 929 prop at 4 volts I get 2 grams of thrust at 1800 RPM.
With a 929 prop at 7 volts I get 4 grams of thrust at 2200 RPM.

It takes approximately 3600 to 4000 RPM for the WL929 to lift off
so this motor has a KV that is too low for our use.
