Default RE: Building the original Byron P-51 Mustang

The original byron wing called for torque tubes for the ailerons leading to 1 servo controlling both ailerons in the middle of the wing. Even though this plane only flys about 85 mph, that little servo really had to labor for this job and all of the slop lead to flutter. So it called for a counter weight to help that laboring servo. BAD IDEA! I have heard of some guys loosing their planes due to this system failing. Most guys now are intalling servos for ailerons in the wings. That is what I did here. I chose a spot and built boxes for them and the servo tray is also the cover.
I am using hitech 5496mg for the ailerons - way overkill but I wont have to worry too much about flutter and I will not have to install those counterweights in the ailerons.
