How to Recycle that Motor Mount
Posted: Thu Mar 29, 2018 10:30 am
Over the years I have found that I generally have better luck running new motor mounts than running ones that have been crashed. The reason is that most times the mounts end up twisted and don't adequately hold the engine after the crash. This is sometimes evident by seeing black gunk coming from an unknown source.
Someone passed a tip on to me that if the twist is minor you can true up the mounting surface with minimal effort. The pictures show what can sometimes be done to true up the mounting surface.
1) Remove the mount from the model.
2) Identify a flat surface. This can be a piece of glass or other machined surface. I used the surface of my saw.
3) Slowly work the mount surface on a piece of wet-and-dry sandpaper. This was 400 grit paper used dry.
