.......I also bought some foam rubber and a prop balancer. The props I got are WAY out of balance.
The hobby shop also didn't have kind of rubber engine mounts. I was thinking of putting in some foam rubber strips or something like that in between the metal mounting plates.
Since this is a trainer I wouldn't really worry about balancing the props. They are going to start getting banged up pretty much from the start. Especially when you start practicing landings, they'll take a beating. Just put them on the plane and fly it.
You don't need to put any rubber on the engine mount. If you do the engine will actually slip out of the mount. Just make sure the mount is tight on the engine mounting tabs and you'll be good to go.
Hope this helps
