Hey guys, I'm looking to try out one of those Kroma 50cc engines and would like to begin breaking it in while I'm deciding on which plane to buy. Does anyone here have some mount plans or a place where I can buy a good one for this? Thanks for the help.

You won't need a motor mount if that's what you mean....you may need standoffs of either hardwood or aluminum to match the firewall to thrust washer distance of the plane you install it on.

If you are talking about a break in stand (mount) then all you need is something sturdy and safe to literally bolt it to. I've seen guys mount em up to large saw horses, old picnic tables, metal stands, black and decker workmate....etc. Whatever it is, just be sure it stays put while you start and run your engine. Think SAFE
