I'll have to double check with a better scale, but I have approximately 5 lbs 5 oz with servos, receiver, and A123 rx pack. I've checked a few other threads as I think this plane is basically the same as the Cermark and Peak planes, and they are all putting their CG's any where from 105 to 120mm. Heck, the wing tube is at 100mm, so I doubt the CG is two inches further back.
