got the replacement brass control horns from esprit models today and fitted them in place of the ones that I originally installed and cut too short. The new ones still only give me 1/2 inch length from the control surface to the center of the hole where the clevis is inserted. Is that going to be long enough for a 3 meter sailplane? Looking through some of the photos of similar sized birds it appears that many have controls horns installed that are greater than 1/2 inch.

Also, the Hitec servos I have (HS5125MG), even when powered up have a tiny amount of play/backlash in the gears...never seen that before. Does anyone else here have those servos? Do you see the same thing? Could I have gotten 4 bad, brand new servos or is this normal? The cheaper sevos I have on the v tail are locked in with no backlash at all.
