Can someone help with aileron differential. I have a Tiger 60 powered with a Magnum 91 and it flies great except when I roll, where it has a tendency to dive. If I do more than one consecutive roll it it ends up in a vertical dive. Almost lost it (thank god for the "3 mistakes high" theory). I assume I need to program differential into the ailerons. But in what direction. Assumiming I roll right, do I want less left aileron (down) or less right aileron (up).
