Thank you for all the input! I found in my shop some towerhobbies TS-35 55oz/torque same torque as the Hitec 225 (I think they are the same?) They just don't have the metal gears I have heavy duty arms for them. What are your thoughts on using them. Also do I need a rudder. Can I just run one standard HT servo for an elevator? I flew my scat cat with no rudder?
