Default cg 1/5 Sig Cub

A couple years ago I built a Sig 1/5 scale cub and I am now re-powering it. I need to know where the CG is. Any help will be appreciated.

All the Cubs I've had liked a fairly nose heavy settings. A good place to start is at 25% of chord and then move it back slowly until it flys like you like it too.

From SIG Manual:

RECOMMENDED BALANCE POINT
3-1/2” back from the leading edge of the wing
IMPORTANT NOTE: Balanced means the airplane sets level
when supported at the desired balance point, not slightly nose
down or nose up.
