Default GP 1/4 Giles 202 balance problems

I finished assembling my Giles. I used an O.S. FX 1.60 engine with the stock muffler, a Great Planes 1.20-1.80 engine mount (plastic), a Sullivan 16-oz. tank, a ProSpin 4" spinner, HiTec 605BB servos and Top Flight Powerpoint 18-6-10 wood prop. I have my receiver and 1400mah battery pack as far to the rear of the radio compartment as possible.

My first balancing attempts showed it nose heavy so I put it on the balance with the battery out so I could place the battery along the fuse to find the ideal spot for a battery hatch. It wouldn't balance with the battery sitting on the tail feathers.

To balance the plane at 7 1/8" from the LE (GP's recommended range is 3/8" to either side of a 7 3/8" starting point), it needs five ounces [X(] of lead beneath the tail. I use a Great Planes CG Machine for balancing and it has worked well with other aircraft.

Did any of you Giles owners experience this problem? Besides absolutely hating the thought of doing it, I don't even know HOW I'd attach a four-inch-long chunk of bar solder to the tail....

Anything anyone could say to make me feel better would be appreciated.

Good flying,
Bob Scott
