Alasdair to help we would need more information. Have you followed the video that is on one of the forum posts from Quadrocopter? http://forum.freeflysystems.com/index.php?threads/remote-unbound-not-fixable.4169/#post-45408
Hi. I hadn't watched that but at first glance I think I see the problem. I don't have the little plug thing. I guess I'll call the store and see if I can get one. Thanks for the pointer.
