I'm building a Goldberg 10-300 Ultimate Biplane that I bought new in 1998 and sat on a shelf. The build is moving along well but I'm thinking of making a change in the aileron servo setup. Rather than mount a single servo in the center of the bottom wing. I'm thinking of using two servos in the bottom wing just to the inside of the interplane strut. My question is what kind of torque rating do I need? Because there are two servos, can I get away with some 35 to 40 oz-in each times two with metal gears? Any suggestions on specific servos? I appreciate any suggestions! Ray
