Stock Motor Mount Thrust Angle?

[father&son]

Hi all,

I'm a brand-newbie with a new, all-stock, non-modified SuperCub LP that my son and I are learning to fly together. Emphasis on "learning"! We expect to have a few crashes along the way, and indeed, suffered a fairly bad one the other day: Nose-down lawn-dart type of crash that cracked the firewall. The prop shaft, amazingly, was not bent. Replacement parts (all stock) from Red Rocket Hobby in Oregon (Excellent service, by the way!) arrived yesterday.

As I was fit-testing the firewall I noticed that the motor mounts to it in such a way as it's angled to the right slightly. Dredging up some old college physics from the depths of my brain, I surmised that this is done on purpose to counteract the rotational effect of the prop which would tend to pull the nose to the left.

My question: The angle seems fairly severe. It this normal? The motor mount is clearly cast that way. I didn't notice the angle pre-crash, of course, so I have very little idea if it's normal, or more pronounced due to some foam crushing from the crash (though the fuse looks fine).

I want to be sure this is okay before attempting to fly the plane again.

I welcome your comments and sage advice.

PS: I'd also welcome suggestions for the right adhesive to use to re-mount the firewall on the Fuse. Silicone caulking or white silicone comes to mind. What would you use?

All have a down and right angle , that's normal if that is what your asking ?

I use foam safe glue, it can be bought at any hobby type store.



Edit: I see this was answered on another thread...Lol

Standard format for nearly all planes is 2 degrees down and 2 degrees right thrust, to offset the torque thrust from the motor, whether IC or EP. My Supercub had roughly 5 degrees downthrust, but that was due to the stupidly powerful motor I installed at the time...(1200KV with a 10x6 prop?) 3D motor with a trainer....looped with 50% throttle....
