Went out right after the first posting and broke ball off blade grip. Different batt though, I wonder if that matters. The second batt is one I accidentally charged at 2.5 amps the first time I charged it and it got real hot but that was months ago. Anyway, completely different flight.
CA the ball back on, then drill a hole through it and CA in some CF (#43 drill for 2mm CF rod, could probably go with 1/16 if you don't have number drills). I had to do that with one of mine and it works fine. Also popped off two of the ones on the BH head last weekend and put .039 wire in those. CF works better but the hole has to be bigger. I also have the DD tail and love it. IMO much better tail reaction and stability.
