Well, I went out and bought an Alpha ARF. The assembly of the plane was easy and straightforward, everything went together as it was supposed to. I put the plane on the CG machine, at 3 inches from the leading edge, and the tail dropped like a rock. It took 11! ounces of weight right behind the engine to balance it correctly. This setup was with the reciever and battery pack between the fuel tank and servo tray. I have since moved the battery up under the front of the fuel tank. What else can I do to get this thing to balance, short of adding a lot of lead?
Thanks,
