First of all, you should determine how much lead you need to add to the tail. That has a long tail moment and you might not need to add much.

Then, if necessary, move the battery pack back. I would put a hatch on the side if you can. If the battery pack weight is on the hatch, putting it on the bottom will pull the screws out on a hard landing.

I don't have one of these planes, but one of the guys in the club does and he can't keep his motor running. I have passed along the comments you guys have made, and I'm sure it will take care of his problem.

This thread had been very interesting.
