I have just the thing to heat the gear, and I think a hemostat would be good to hold it while heating/installing the gear. Thanks for the idea. I will give it a try...as soon as someone sends me the darn motor. I had ordered with the 'copter from RaidenTech (forget that) and I have ordered another from HOBBY ESTORE along with the 'copter from China (and I have no clue as to when it will arrive and anyone want to put money on whether or not it is even included with the order with the helicopter?). MYRCSUPPLY does not stock the motor, unfortunately. They checked while they had me on the phone and were apologetic that they could not send me one or one that would work/substitute for the correct one. They get an A+ for effort.
