This is my first post. I recently got in to rc and have had tons of fun, recently got a simple scout. I have been flying it now for over a month no problem. On one of my earlier planes I had brownouts and since have always flown with a receiver battery for redundancy. A couple days ago I decided to paint my scout and had to take some of the electronics out. My first flight after paint I noticed delayed response and sometimes none at all. On the second flight thinking maybe it was just wind I lost all control and crashed. Nothing terrible but I was stumped until I got home and realized the reciver antenna was in the plane wedged between the esc and battery, certainly that was the problem so after fixing it I went out again today did two range tests, one with the antenna in the wedged position and one taped on the underside where I had it before I painted and had no issues. The test with wedged I. The esc has it loss signal and outside it was fine. I decided to fly thinking the problem was solved only for it to loss signal and crash again. I have no idea what could be wrong, any help would be greatly appreciated.
