The planes a matrix and its my first 2m F3A airframe... Firstly, thanks for the info guys. The full story is I am getting 3 "brand new" but second-hand super servos off an ex JR sponsored pilot for quite a bit cheaper than new. I havn't received the servos yet (in the next few days) but am assuming that they are similar to the 7005. They are low profile super servos 2 which I have been told run at full power all of the time (ailerons) and the other which is newer, that I was going to run on the elevator and only runs at full power when in use, I was told what servos they are but cant remember !!!, I've been 100% a futaba user until now. I do know that these super servos have nylon gears so really what Ed says scares me. Has anyone else had problems with the gears stripping. I'm sure that they will handle the elevator but stripping the gears would not be a good start to my first 2m plane. thanks
