Really what you want to do is set the Endpoint adjustment at 140 and then set the throw limit mechanically, you shouldnt need multiple rates on a trainer. But you always want you maximum throw (highes rate) set at the maximum resolution so that you take full advantage of the sensitvity of the Tx. Really well setup planes are almost always setup like this.





To affirm what has already been said, and this is a little advanced so dont let it confuse you. Save this information for after you are ready to move on to a more aerobatic plane.

IF you do use dual or triple rates, set the enpoint adjustment for that surface or pair of surfaces(ie ailerons should be the same EP for each aileron) at 140 or whatever max EP is on your Tx. Then set the highest rate in the DR/Expo screen at 140 and zero expo to start. Then make adjustments mechanically to put the high rate throw where you want it by 1st moving in on the control horn, and then out on the servo arm. Also try to make your adjustments to balance the throw mechanically if possible and only use subtrims once you cant get any closer mechanically. Mechanically imbalanced throws that are corrected electronically result in poor performance most of the time. You end up fighting weird coupling issues and all sorts of nuisance problems.

Once you get the highest rate done pick a dual or triple rate switch and assign the various rates to the same switch, and dial down your DR setting in the DR/Expo screen to get the desired throw on the lower rates. .

If possible it is desirable to move the pushrod out on the servo arm as little as possible to get the desired throw and no more. I would move in on the control horn as much as possible and still maintain good geometry before I started moving out on the servo arm. The closer the pushrod is to the centerline of the spline the greater the leverage the servo has and the less strain on the servo gear train. BUT sometimes on 3D planes where you need > 45degrees of throw it is necessary to get a really powerful servo and then use a real long servo horn. Sometimes as long as 2" to be able to get the throw you need.
