IMPORTANT NOTE: This gear has not been verified yet, and uses only rough measurements. I will check the measurements when my digital caliper arrives, and update this after I test the physical part. Download if you'd like, but it is at your own risk.
This is a replacement motor gear for the B blade motor on a Viefly V11 helicopter.
After stripping this gear on mine, I ordered another 'copter, thinking it was a blade and it would come with a spare. Nope. Just a spare tail-rotor. However, after I had that, I figured I might as well take the first one apart to figure it out. That's when I discovered that the issue was a stripped gear.
Yay! I finally got the model to pretend it's the right size! I don't know why everything was scaled up, or why part of the model was missing, but it seems to be ok now. A good price, too, now that it's not magnified.
I need to verify the measurements and such after I receive my caliper, but then I should be able to order the part I need to fix my helicopter. Then, I should be able to pop it back on the motor shaft, put the 'copter back together, and give it a try!
It sure would be nice to have both helicopters working!
