Just got through flashing all four of my proton 30's from HobbyPartz, all went well and they all seem to work. Thanks everyone! BTW, still can't get Chatch's program to work... locks up now. I used eXteme burner AVR, just opened the hex file and clicked on "write". Even tried one of my RCTimer 10amp... worked great, looking forward to trying them in the air.
