Howdy! I have an aircraft which uses elevons. My Eclipse 7 drives the plane pretty well, but I've run across a problem I have difficulty sorting out. When I set the throws mechanically to give me the high roll rate I want, the elevator control is too sensitive to be a comfortable flyer. When I set the throws to the elevator response I want, of course, the roll rate isn't as high as I'd like it.

What I really want is for my elevons to be able to go full deflection on a roll, and only partial deflection in response to elevator controls. Basically, 100% aileron, and about 50% elevator. However, trying to set up endpoints only adjust the servo on a particular channel, not the intended control surface itself.

How do I set an endpoint so that it modifies the control surface deflection *after* the mix has occurred? On my Futaba 6exa, it was very intuitive; setting an EPA for elevator would adjust the throws of both control surfaces in the "elevator" direction, while retaining full aileron control. I like my Eclipse, but I'm so frustrated with trying to figure this bit out that I'm almost ready to go back to my Futaba!

Thanks in advance for your help.

I have a Eclipse 7 set up for elevons and it works very well, i use the dual rate fuction
so i can have high rates on elevator and low on ailerons as my plane has a very high
roll rate. i think my epa is set to about 90% for both ail and elv but i use the dual rate
to reduce the aileron throw, i think you find the setup almost the same if you use the
futaba radio.
