My kit built 4*60 took 10.5 oz of lead in the nose to balance it. The plane weighs 9 lbs dry.

It flies great.

Responses here on RCU seem to indicate that 4*60s are tail heavy.

The guy I talked too at SIG about this said its OK; "got big wings" he said.

Just do what you have to to balance it & go fly!
