RE: Sebart Wind 110
Thank you Zebel. I also heard from a trusted friend in our club to leave the collar on, so that's enough for me.
I took the aluminum mount that came with the motor and cut the ears off, and mounted it on the front of the nose ring of the plane. I will use this as a guide for cutting the nose ring, and it looks like it should work out very well.
Also I made a mistake earlier on saying that the motor shaft was too large for the bearing - it is not. I thought the recommended Hacker came with a 6mm shaft, but it must in fact be an 8mm shaft also.
Going to try some patience and not cut the plane tonight, rather do it in the morning when I'm well rested, there is more light, and noise won't be an issue.
