Hi,

In reply to your concern about the engine mounting ("The engine mounting procedure concerns me a little.... The engine is basically clamped in. "), I can tell you they work fine. My first student used one of those mounts, and I cautioned him against it. When he used it anyway, I cautioned him to constantly check the screws. When he put it in the second plane, with no problems, I asked him if it ever worked loose. (Not detectably, he sez.) On the third plane I shut up. Looks like they've got a winner.

I would still check them every few flights....

The 10 X 6 prop on that engine might be a little noisy, the 11X6 worked good (on another student's plane.) I cautioned him against the LA, said it wouldn't have any power, he'd be disappointed, etc. Turns out it has plenty of power, handles an 11X6 or 11X7 just fine. If you're a student, you'll find the 11X7 makes the plane a little fast. (did I say THAT????)

Good choices. Enjoy.
