I'm currently building this plane and want to know if standard servos are adequate. I've been told by a local flyer that upgrading to some of the high speed / high torque servos that HiTech makes would be advisable if I plan to use the plane for some 3D maneuvers. I would also like to install a pull / pull rudder system and need guidance there too. Also, would like to upgrade the hardware, any advice?
