Hi everyone. Had a bad crash the other day and ruined my autorotation tail drive gear. Just received a new autorotation gear but need some information regarding removal of the one- way bearing shaft from the old hub or if it's easier just exchanging the old hub with the one-way bearing still in place with the new gear. I have the old hub/one-way bearing shaft combo out of the old gear ( no damage to these parts) and they are still together. Is there a way to remove the new gear's hub and install the old combo ( hub and one-way gearing shaft)? If not, how do I exchange the 0ne-way gearing shaft from the old hub to the mounted hub in the new gear? Any videos, articles or just a an explanation would be greatly appreciated. The heli is a trex 450Plus.
