Hi I'm going to use the round servo horns..Now the 3 holes on side of the horn, which one will give me more travel..

Thanks Dan

Out on the arm and in on the control surface gives more travel.

HS-81 Sevo horn set. The round horn does not, in this instance have a series of three holes radiating out from the center to provide for short or long throws, all holes are equidistant. However, those set at 90 degrees will give equal left & right movement whilst those forward and back of the center will give more one way throw than the other.

Hi Alan I was just trying to see what responses I got in this forum..Maybe next time I'll post my RX/TX questions here..Here is another question is IT possible to have more up then down in the ailerons just using one servo..The plane I'm building now calls for 3/8 up & 1/4 down for the ailerons..The wing servo control horn has the regular 4 arms..
Thanks Dan

Absolutely no problem to set up differential with a standard servo and a straight cross arm (or star with other arms cut off) or the round horn as supplied with the HS-81. If using holes of the servo disc or a straight servo arm at right angles to servo, simply rake the aileron arms backward if servo is under a high wing model or forwards if servo is mounted on top of a low wing model, as decribed:

In need email me via my web page link and I will send a few pictorial jpg's of examples.

With your low wing plane the servo would be above the wing and the arms should be closer to the trailing edge than the leading edge.
