servo torque needed for Flaps
I am building a 66" span P40 with split flaps - Will standard servos one each for eaxch flap be ok , and has anone used mini or smaller ? I know standard are 43oz of torque or better but the micro are 15 oz of torque . Any suggestions on saving weight would be apprecaited if I can maintain safe control .

RE: servo torque needed for Flaps
I'm definitely getting old. When I started flying in 1972, a standard servo was 11 in/oz, and a heavy bruiser of a servo was 14 in/oz. Nowadays, a micro servo is 15 in/oz. (SIGH!) BTW - I would think that a medium sized servo would serve your purposes unless your talking about hanging a barn-door out into the slipstream.

Hi LDM had the same question a year or so ago with a 1/7 P-47-I decieded on 2 Hi Tech HS 81 "metal geared servos," one on each flap using a 'Y' connector of course,they have been flawless in operation and more than once I poured the coal to the O.S. 120 pumped for a 'go around with flaps still deployed.
