I'm not positive but I would say at or about 20% up/down for AIL &ELE and 25% for RUD for normal flight.
40% for all for 3D.

OK, that sounds pretty good, Probably end up about 25 to 30 degrees, and a little more on rudder. Like it a little more active, and triple rates will help..
Another question is this, There are four aileron servos, 2 per aileron, they are presently Y'ed together, and run on seperate 2 channels at receiver.
I think that they should all be on seperate channels, Run as four ailerons on seperate channels. As the ailerons are now, they buzz like crazy, ailerons seem to be a little twisted.
I can fix that, but I think things would be simpler with each aileron servo on a different channel, stops twist in the ail, and the servos would not buzz..Does that sound CORRECT?

Depends on the servos and the TX/RX you are using, the twist might not be the only issue, there are several ways to pair the servos to eliminate buzzing, Match Boxs, Powerexpanders with matching, Programing the servos or seperate channel mixing. It depends on the equiptment you have and or are willing to buy.

I don't have a radio /RX that will do it so I use match boxes. I do know certain JR/Spektrum radio systems will do that.

I'm not a JR guy but I'm sure you can set up the two servo function and then use the extra channels to mix the extra servos to each of those Ail channels, just use prog. mix. You have the channels and a RX that can take the amps, got for it with what you have.

I'm sure some JR expert can talk you through the functions,, might try asking in the giant scale forums

good luck
