Aluminum 8mm Motor Mount Third Bearing Support?
Curious if there is an aftermarket Aluminum 8mm Motor Mount Third Bearing Support available for the Goblin 770? I have searched numerous forums and websites including the SAB to see if they make one and have come up empty. I have read that some have switched out the 6mm bearing but I'd prefer to not do that. I realize that the 8mm shaft it robust but I'm concerned about premature wear of the motor's bearings. Given this application is for a scale fuselage with a lot of time and money spent on it I'm trying to eliminate as many potential issues as possible. Given my projected weight of nearly 40 pounds I need to step up to a Pyro 800 or 850 on 14S.

Thanks.

Thanks for the reply. I have also heard of quite a few motor bearings going as well! That's a mighty long shaft for that much torque and to put all that on internal bearings seems risky to me.

I've flown my 700 with a Scorpion 4525-520 Ultimate Mikado edition with 8mm shaft for over 2 years now without any bearings going bad, and I have never oiled them or done any maintenance whatsoever on the motor. Out of curiosity I pulled the motor apart when I was doing a basic tear down for maintenance about a month ago and the bearings are still fine. You're not going to have an issue with your Pyro.Nick Crego
