Installing/removing pinion gears
Trying my first electric, an Eflite Mini Funtana with a Park 400 brushless. What is the best way to install a gear on the motor shaft. Heat comes to mind, but if you don't get it in the right position the first time what do you do. Is there a gear puller available for these small motors? Thanks in advance.

RE: Installing/removing pinion gears
I found the answers elswwhere. Press fit the pinions using a vise or clamp. Be sure the back end of the shaft is supported. GWS sels two versions of a gear puller. One for shaft diameters equal to or larger than 2 mm, the other for smaller diameter shafts. Best advice is if you have to pull a pinion gear DO NOT reuse it.

I use the drill press. Close the chuck up, press on the gear. If the gear needs to be further on the shaft, open the chuck till it's a bit bigger than the shaft, then press away
The face of the jaws is ground very flat so it will align the gear with the shaft very well.

RE: Installing/removing pinion gears
Works great. I have to have a little less than 1/16" of the shaft protruding beyond the pinion, and your suggestion to use a drill press is just what I needed. THANKS!
