Do you people not think? Weight is not his problem, balance is. Adding a pound of lead at the CG won't do a damn thing for him.
A quick recap - There are two separate discussions going on, so reading comprehension is required.
1.) On the issue of an airplane being "two light", add weight and get back to us.
2.) Moving the wing back on the fuselage will balance the plane. Easy to do when it has a wing tube and simple mounting.
