RE: WillHobby Yak 54 ARF Question
Mine was the same. I had the SPE 40cc gasser up front and two huge "C" size 4.8 batteries and it was still tail heavy according to the manual. The manual is wrong. When I first took off it flew dead straight and I was no were near the correct CG. I don’t have the correct CG setting but if you put everything up front, you’re real close. Hope this helps.
