Thanx for the suggestions... as for using shorter standoffs that would make things much better, but I'm not much of a handy woodworker so building the box out is a no go I also don't think the mounting lugs on the engine would break, they look small in the picture but there pretty thick, I think the box would break before they would. what kind of bolts would you use to replace the cast aluminum ones? They are a couple mm thicker than the ones that come with the engine but made of a different material... Why not Use Metal standoffs? I would think that would be better than wood, doesn't wood crack are warp? (Im kinda new to gas only been flyin them for about 2 months).
