I am about to help my son fly his Hobby King Yak 54 (the small one).
I tried a search, for the earlier HK Yak 54 thread but no luck.
Anyone have any ideas for a C of G before the maiden?
Control throws? I will check the current draw with my E-flite Wattmeter.

How big a LiPo do I need to fly this? I have a TP 3S-1350-25C all ready to go, or do I need a larger 3S Lipo?

I seem to remember the gear box shaft to prop is very flimsy, and bought a GWS replacement part (for the first crash, when. the shaft bends/breaks)

Thanks for any answers, or a link to the HK Yak 54 thread.
