I am at a point in my build of a different plane that I need to consider mounting the servo and stuff. Looking at your video it looks like you installed the servo in a way where once the plane is finish there is no way of replacing the servo if need be.

Is this how you do it normaly or because of the nature of this model.

If you mount the servo on a 1/16th thick piece of plywood that you screw onto the bottom of the wing, you can gain access to the servo by removing the plywood plate.

The pictures at http://www.rcgroups.com/forums/showp...&postcount=171 do not show the plate but do show another example of the same type of installation that uses magnets at the spointer's tips to keep them down flat

That's exactly how this spoiler servo is mounted, just glued to 1/16" ply mounting plate which is screwed flush to a custom made "frame" on the lower surface of the wing. Good access to the servo as you suggest.

I like that setup. I am building a Windlord flying wing (build log at www.rcgroups.com/forums/showthread.php?t=1680750). I am going to use your installation method for the spoilers. If the Hitec-55 is sufficient for Hobby Hawk spoiler, it should be enough torque for the Windlord spoilers.

The blue Hitec HS-55 looks cool. But, due to the brown laser cut edges in my partial kit, I am going with opaque covering. So, I may use Futaba S3114 servos since they are about the same weight with a higher torque rating, albeit $5 more per servo.

Futaba S3114 - .21 torque, .28 oz weight
Hitec HS-5 - .1527 torque, .27 oz weight
