Well,,, how many channels do you need to have for a stock wattage cessna and ailerons? I'm guessing around 4-5.... My other question is how to add ailerons onto my wattage cessna.??? I'm pretty sure it's possible.

Thanks!

4 is the bare minimum if you want to still have rudder control. The easiest way would be to cut a slot for a servo in the very center of the wing at the top. Then you could cut out the ailerons on the wing's trailing edge to whatever size you want (the bigger, the more stress on the airframe but the faster the roll rate) and add some dubro control horns or something similar along with hings and pushrods and you'll be good to go.

For one servo for ailerons wouldn't it just go either up (or down, depending on wich way you choose)? If not how would I set it up? Drawings would help.

Thanks!
