QQ 73" Yak Balancing problems

[jzcode49]

I attempted to balance my Yak and get a idea of where to position my 2 Lipo packs. The manual say the CG is 174MM from the trailing edge. Something don't seem right. 46oz of Lipos placed at the back of the canopy wouldn't balance it out. I have an AXI 5330 mounted on an aluminum mount. The manual show a battery pack placed above the glow motor which wieghs more than my AXI. So I don't know what is going on here. I took the measurements at the root of the wing. If you are suppose to take the CG measurement at the tip from the trailing edge, that would shift the CG ahead of my marks.

Does anyone have a QQ 73" Yak that can help me figure out what's going on here? The manual is not updated and I have found several things that did not match the instruction. So I'm wondering if the CG has change since this manual was printed? Thanks....

I think I figured it out! The wording in the manual didn't make things to clear. The measurement is taken at the wing tip, not the root. That moved the CG about 3 inches. Big difference. I balance it on a great planes balancer which isn't designed for that big of a plane. So I have a good idea now where to place the batteries. I'll close the thread.
