Feket663 The digital servos that Hobbyking recommends seem to be a decent choice however while i was building i realized the servo screws provided with the servos didn't work with the servo arm extensions provided with the kit... but i was able to use screws from other servos that were long enough to screw into the servo with the extensions.

Although, i have not yet flown with these servos because i am having issues with the Donkey motor that HK recommended for the plane.

Any ideas would help... the problem is when i throttle up the motor it runs fine until about half throttle any more throttle i start to get a loud squeal and then the motor stops spinning. Is this just because the motor is junk? i tried a much smaller prop and it seems to swing it to full throttle but the prop isn't big enough to fly the plane. My issue is with the 11*4.7 prop that is recommend for the set up.

if it's the motor does anyone have a good suggestion that hobbyking has in stock?

Again any ideas or thoughts would be helpful, Thanks.
