Balancing

Balance the 

Yak 54 

6-7/8 to 7-1/4  back from the leading edge next to the fuselage.

For extreme 3D flying you may want to move the CG back even farther after you are

familiar with the way the 

Yak 54 

flies. Just remember that the further back you go the

more sensitive it will become. With extreme throws the model can get beyond the abil-

ity of novice pilots very quickly.

Good Luck and I hope you enjoy flying the 

87” Yak 54 ARF

.
