E-flite Byp Yak 3D ARF - Manual (Page 35)

The recommended Center of Gravity (CG) location for
the Byp Yak is 3
1 /
4
" (82mm) behind the leading edge
of the top wing.
The battery is located as shown in the photo. Secure the
battery using hook and loop material. It may be necessary to
move either the ESC or receiver to achieve the correct Center
of Gravity.
Weights can be used if necessary, but will add to the overall
flying weight of your model. This would be a last resort to
achieve the correct CG.
