In the rush to complete our shooter, our team made a mistake calculating gear ratios, and we discovered that we needed a 1:1 gearbox for our 775. We took one apart and ground off the teeth on the ring gear then carefully glued together the four gears on the gearbox. We left the teeth that would mesh with the gear on the motor's output shaft unglued. After running these motors we discovered that they heated up too much due to what we guessed was the shaft slipping in the bearing. Then, because we didn't use high temperature grease, the grease would slow down/stop the motor if it was cold. We have another one with different lubrication that doesn't slow down, but the gearbox gets really hot. Does anybody know a better way to do this or a solution to the 1:1 problem? Also, I recall seeing a post about doing this on CD before, but I haven't been able to find it by searching.
