Byron Waco UPF7
 

I haave recently acquired a Byron Originals Waco UPF7 that has very few if any flights on it . It is G62 powered...Before I fly it, I want to double check the C og G ..Instructions say to balance at 7/8 inch ahead of LE of bottom wing...I ttransposed the leading edge to the underside of the top wing (with aircraft perfectly level) and then went fforward the 7/8....It balances slightly nose down with no weight (except for battery) needed. Does anyone have this aircraft or know of anyone with one so I can confirm the balance and weight issue? I think its right, but want to make very sure before I fly it, as its a very nice bird. Many thanks...
