Shane. I have several aircraft using the dual aileron configuration using two separate channels. It's easy to set up and easy to get to that program in your radio. Allan is right. Use the capabilities of your transmitter. I have one plane with Y connector for dual aileron config but it is just that. Dual ailerons with no capability to do anything at all with them. My other planes have flaps, and differential.

I also use a 6 volt battery on my Rx's that provide you with more servo speed and power. My batteries are all 1200 mah or greater, by the way, so I don't worry much about running them low in flight.. I check them before flights and recharge when necessary. I only mention that because if you are going with more than 4 servo's as on planes with a single servo on the ailerons, you may find it more comforting to have a slightly higher capacity battery with the higher voltatge.
