Ok,
I'm getting a little neurotic at this point trying to get the best servo geometry on my Jet Legend F-15. I'm using JR 3421's The lowest I can go on the servo arm is about three holes up on the JR arm to get the required throw and that causes me to bring my end points down to about 70%. Any lower on the arm and the clevis binds on the servo hatch. The horn is the standard fiberglass with one hole. If the servo was a 100+oz/in servo, I wouldn't be so concerned but the 3421 is about 75 @ 6.0 volts which is what I plan to run. Just curious if others have ran into this problem particularly with the F-15. I realize the ailerons are pretty small and the F-15 ain't no speed demon but I'm just not sure if the setup is good enough for the mini servos. Thanks.

Marty
