Default Does any radio handle split elevators?

I am ready to replace one of my old radios and I would like to know if any computer radio allows split elevator controls. I would like to control each elevator motion so that they are "perfectly" synchronized. The available elevator reversers do a good job of reversing and aligning the elevator sides at neutral, however, the two servo deflections are not matched resulting in misalignment.

Maybe I just need to buy more expensive sevos?

I can't speak for all the radios, but the better models in all makes will control split elevators. Some of the cheaper computer radios will do it too, but not as well as the more expensive ones. I do this in the 9C in almost all my planes. It works well and you can dial it in all the way across the throw of the surface instead of just the endpoints. I think the cheaper futaba computer radios can only do it at the endpoints and maybe one or two in the middle. Stay with the better radios and you will have a lot easier time with it. You can't beat the 9C if you ask me!

I downloaded a copy of the Airtronics RD8000 manual from their website (airtronics.net)... acording to that, the RD8000 will do split elevators.

If you want to avoid channel seperation issuses (one elevator responding a few ms before the other) you'll want to look into something like a matchbox of futaba's mixer to control the split elevators. Sport fliers will have less of a problem with it than people that like to do pattern or high precision flying.

I have a Futaba 9CAP and it handles split elevators very well. You can set individual center positions, throws in either direction, etc.. It is very easy to use.

the 8U, 9C and 9Z do dual elevators. 6X does not do it well...it doesnt have a built in mix, and ifyou use the mixer to do it, you will find yourself unable to trim your elevators in flight.

I agree, the futaba synchronizer or JR matchbox are great choices to resolve this question without having to buy a new radio.
