I need to find out how big of a servo I need. I am getting back into flying after a 12 year leave of the hobby. I am going to buy a 70" Cermark SU-26. Will have a 28cc. gas engine. When I left the hobby I had a Goldberg 72" SU-26 and I went withlarger sevros than normal but not 160 0r 180 oz. in. of torque. I am going to go with the metal gears. Any input would be helpful.
