yeah, i gotta admit it seems a little dicky to me.

I guess any mount is only as good as the nuts and bolts holding the motor down.

I began using bakelite mounts on the motor, which would then bolt to hardwood bearers in the plane. The idea is that in a crash, the plate would break allowing the motor to escape with less chance of breakage, and potentially less damage to the fuselage. (kind like breakaway engine mounts in the crumple zone of a modern car)

I recently used to use nylon engine mounts, screwing the motor directly to the plastic mount. Cheaper, easier and again the bearers would break in the event of a crash.

the Mounts that require a metal plate to "clamp" the motor down, from what I have observed so far, are all made of alloy. Am i right? Looks a little inflexible to me and i prefer the idea of the bolts going through the actual lugs. If a nut came loose, you still have a chance to realise a "wobbly" motor. (use lock nuts of course, so vibration wont let them fall off).

Again, i repeat that any solution is only any good if the bolts are tight and inspected regularly (as the previous posts would attest). However, I believe that bolting directly to a mount (using locknuts) gives you a wider window of opportunity to find any possible problems.

While I am here, does anyone know of a special mount for a magnum 4stroke rear induction motor?? this is my first 4 stroke!!
