Matching dual elevator

Post by heliperry » Sat Apr 20, 2019 2:37 pm

Ok, I'm stumped. I'm trying to match my dual elevator movement while setting up my throws. They match at 0, +100, -100% but when I reduce my throws per plane manual they won't track the same. I'm running open tx in a Horus X12S. I've got one left servo on channel 3 and right on channel 10. I'm running a sbus and with two receivers. Not sure what I need to do. This probably isn't enough information.

I think it would be easiest for someone to help if you posted your .otx.
If you do be sure to note which model you are working on.

I'm guessing it is a setup error, provided you have the same model servos and the location of pushrods are in the same control horn locations

My suggestion is to (temporarily) use the throttle stick to control the elevators. Now you may move the elevators through their complete throw and keep them in any position. Watch the elevators and check they track each other through their complete movement. If they don't track each other, apply a curve to one of them (9-point should be enough) and adjust the curve to get the elevator it is on to match the other one.

I just got back to this post, I think I'll try your suggestion.
Thanks Mike, sorry for not getting back so soon. I'm not able to get this site to bing me when I have a reply.
