Mine is ALMOST ready. I found my balance point, just a little more than 4" back, with the battery pack right in front of the radio, which is under the wing, just in front of the servos. Now I'm going to mix some epoxy, thin it with alcohol, and seal the covering seams in an attempt to keep the covering from peeling off. Then it's break-in time for the Magnum .52 XLS. What fuel is everyone using for break-in? They are calling for 10%, with caster oil (not synthetic), but as rich as I break them in, I'm wondering if that is neccesary????
