Argileh,

Here's a mod I wished I had done when origially building my 4 *. When it comes time to hinge and mount the ailerons, add an extra hinge one bay in from the wingtips. The 4 * really floats and it's roll rate is a bit slow. If you add the extra hinges now, in the future, you can shorten the wings and have a hinge already in place to support the tips of the ailerons. Shortening the wings is a common mod to increase the performance. I shortened the wings on my 4 * for it's second season of flying.
