Ask and ye shall receive. The only reason I mounted YSs and Hyde mounts with 6-32 screws was because the mounting holes were too big for 4-40. I don't ever use nylon in any shear application, and that's what you'll be getting with the torque of the motor.

I know I don't doubt the construction integrity of your motor mount, and it's doubtful that others on here do as well. The the professional appearance of the construction of the mount is a testament to your composites background. I just think the thing is too damn complicated. It's neat, appears to be built well, and is definitely outside of the box thinking. However, I think most would agree with me that you would have been better served to extend your motor box sides a couple more inches further forward and bolted the motor directly to the firewall using standard (4-40, 6-32) hardware.

My only other comment regarding the airplane is the batteries appearing to be mounted in the bottom of the airplane. From what I've seen, this is not the optimal arrangement. Primarily for a lazy person, like myself, I don't like flipping my airplanes over. To have to do that every flight stinks. Secondarily, and probably more relevant to the discussion, I've never been crazy about the way pattern planes fly with the batteries so far off of the fuse centerline by being bottom mounted. I've seen several Japanese pattern planes that were retrofitted to electric with batteries in the belly pan, and I did not like the way that any of them presented. The airplanes all appeared to fly with the nose down and did not track straight. My thoughts are that this is a function of vertical CG. The same aiframes that were either glow powered, like they were originally intended, or that were modified to have the batteries sit closer to the fuselage centerline appeared to track much better and the fuselages sat at a better angle in straight and level flight.

This commentary is worth what you paid for it. I am very impressed with your work, as you appear to be a heck of a craftsman. Kudos to you for taking the path less traveled, as well as utilizing a design that has fallen out of favor due solely to its lack of being flavor of the week, on top of adapting that to a 2M airframe.

Good luck with your project, and I for one look forward to seeing its progression.
