Ok. I let the daughter play with my summit and some how the trany servo stopped working. So I figured it was time to do a cleansing while I was waiting for the new servo. Well today the servo came and I installed it and got it up and running. Everything works great except that when I get about 60 feet away it just stops. I put new batteries in the remote and fresh charged batts in the summit and still no change. I also found out that when I put the remote behind my back that I have no movement in my summit. When I bring it back front of me I have full control. what when bad?
