There is nothing wrong with using Dual servos and there actually is one benefit when compared to strip ailerons used with a single servo and torque rods. You will get a more slop free System by nature of the short pushrods and virtually zero torsional flexing of the rod and aileron itself which often there is with a poorly assembled/built airplane using torque rods.

This torsional flexing and aileron bending (because it is being moved on the inboard bitter end can an many times is a conributor to aileron flutter. Now granted we are talking about trainers where flutter is rare but when we get to many sport aerobatic types using torque rods then this is an issue such as some older pattern types.


Its great that you want to experiment, Thats a good thing and what this hobby/sport is all about. For wing mounting servos in a trainer wing or any built up wing its not really neccessary to to use the buried servo mount system with a plate. If one cares to do just a little covering film work its very, very easy just to do a surface mount and all thats neccessary is a few sticks glued in to form a box and have someplace to stick the covering to. These have the tremendous advantage of allowing adjustments done literally in seconds rather than requiring disassembling a servo plate. The first two are full surface mounts with the servo lugs directly on the wing surface and the third yellow wing had the top of the servo lugs flush with the wing surface.

The one thing I would not do is use two servos in the center as you remove none of the torque rod/aileron flexing that way.
