All,

Question:

I'm building an 0.90 size AKM SU-27 propjet with leading edge flaps. Space is at a premium right now so I was considering using micro servos to actuate the leading edge flaps. The servos' torque output is 75 oz and have metal gears with dual ball bearings.

My question is will they hold up?

The leading edge flaps will only have 15 degrees of travel from the straight to full down position. I've rigged it so that in the up position the control rod exerts no load on the servo itself. This locks it into the up position (figure 1). When down the leading edge flap sits flush on the wing locking it in the down position (figure 2). Photos courtesy of Dan Savage 2004.

Thank you for your time,
