RE: Add a Channel to 2-Channel X 4' Sailplane?
It's fairly easy to add ailerons to a plane like this. I've done it to several you would want to add them to the outboard portion of the wing. If your using flex cables you will need to use a pull/pull type of setup simply notch the wing to run your cables and epoxy or even tape the guides in place. I have found that it's a lot easier for a beginner to start with a four channel radio rather than learn on a three and switch to a four. On several foam planes I just add a servo in each wing for the ailerons... I would stay away from flaperons they cause tip stalls.
