Sorry for you loss bro. I lost radio contact on my yellow F16 a few months ago and it flew to almost out of site. I ended up using my sons big nasty trainer plane and cut a hole in the fuse and installed a small video camera. Took off from the airfeild and got into the back of a truck and flew it while my freind drove my truck back into the woods where I saw it and I did this 3 times covering alot of ground and found it this way! I was shocked it really worked but it did. Before I used a full scale piper cub and couldnt find it but my sons ugly little plane got it!
