This is great information.

The plane flys wonderfully when doing maneuvers, I have the most problem when landing.
I never thought about weight. I think that could be part of the problem. I haven't weighed the plane, but I'm sure it is on the heavy side. What if I drilled some lightening hole in the stock aluminum gear? Would that weaken the gear too much? The battery is already moved back and I moved the firewall back an inch also, so the fuse is an inch shorter. I did that so not to have to add too much lead to the tail.

I do have the flaperons programmed in, I will try and set up a switch.

Tip plates? I don't know if I want to do that, they would take away from the scale appearance.

I was thinking on adding some wing tip caps and shaping them to the airfoil to smooth out the exit of the air, and in turn probably
add 1 3/4" to 2" on the span. Would this help?

Thanks all, Keep the ideas coming.
