I would have to think about your question on getting my 6DA to do the 7 channel crow etc (and get my manual out).

I know my 6DA wont do everything the computer radios do. The problem some people who are new to computer radios is that they think they are a snap to setup and configure. Most hobby store sales people stress that point. Even Futaba and the rest of the manufacturers stress easy programming. For most people they will not be easy to program the first time or two.

Most people will spend 2plus hours just to get the basics down.

Then like I mentioned a month later you add a plane.......Im pretty good with hightech stuff but most people including me are going to have to get that manual out again........and you better take it to the field with you too.

Most of us Sailplaners mix the rudder and eilerons mechanically. And even the elevator/flaps, though I sometimes mix those functions with the 6DA I prefer to mix mechanically most of the time because it takes less servos.
We glider guys dont have the spacious living quarters of the motorized planes.

I realize the motorized guys need separte control of these fucntions so hard mixing might not work for them.

I think the new computer radios are amazing.......I spend many hours building........so I prefer the charge and run radio.

I just added another penny's worth.
