I used 6/32 bolts to mount an OS .72 Surpass 4 Stroke. The bolts fit the mounting holes well, and held the engine firmly in place. I used the Dubro drill/tap set. It worked like a charm.

I have used this tool on three planes for the engine mounts and servos. It is one of the most indispensable tools I have!
