Wade, I have the Stinger 60 ARF and I installed all components for the most part as per instructions. The only difference was installing the battery about 3 inches behind the servo tray and adding about 6.5 ounces in the tail section behind the battery. That was my biggest problem. I have a Super Tiger 90 with a pitts muffler. CG is at 4 3/8" from the leading edge. She flys nice....real nice. Good luck in whatever you decide.
