Initially, I did the "put both wing panels onto the wing tube and streatch a string" trick from the wing tips. I had put a piece of maksing tape under the approximate positon so with the tape pull snug, I made a pen mark on both wing panels. Then when I put the fuselage on and suspended the wings from the balancer, I could move the batteries around to get it to balance at the correct point!!

What is the weight of the BME 110 + prop + spinner/backplate + mufflers (DA 100 about 6.5 lbs for these items)? With my setup, I have two 8411s in the tail, two 4800 Duraltie Plus Li-ion batteries on the rear of the servo tray with the 2800 Li-ion iginition battery on the front of the servo tray.
