fit the splines tightly though � you might check this if using these arms. Lots of folks use the 173 on bipe ailerons (which tend to be smaller). Some time ago I measured servo current draw on each surface and ailerons were by far the highest � as Peter
notes, big surface. At 7.5v they might be OK, I use the BLS171 which has 60 or so more oz-in torque. I�ve also found that servos slow a fair bit whenever current draw exceeds 60% of stall current � another reason to err on the high side.</span><o:p></o:p></p>
