I am at the stage where I need to mount servos in my plane. Where did you guys install the elevator servo on the stab? Center of stab OR towards the inner side? I plan on using JR8611 per elevator half. I also plan to use single 8611 per ailerons installed in the center of the wing. Is a single 8611 good enough for the ailerons? The other option would be to install two 8411's per wing, and use the matchbox etc to match centers etc...too complicated basically...
