I was thinking some of the Micro types would work fine seeing as how a lot of torque probably wasn't necessary. I wasn't "so much" concerned about saving an ounce of weight as I was thinking more options for installation with a much smaller servo. Smaller servo would fit in a smaller space than a standard one would. I already have several extra Hitec's (like cheap-o 322's and 325's) Ive bought as throttle servos in planes that never got started and were sold, still have the servo's.
