Matt is right on with the elevator throw dimension, but if I recall, the "as published" CG should be set at 8 1/2" as a starting point, measuring from the TE aft down the fuselage on the wing root. Make a mark or drill a #40 hole on the bottom of each wing fillet (fuselage) at that location to make it easier from then on. Drill the hole about 1/4" inboard of the edge of the root.

Balance it with zero fuel in the mains and header, making sure you have a full UAT, and the landing gear down. It should hang very slightly nose down at that measured point. When the nose gear retracts, the CG will move very slightly aft.

Weigh each wing panel, seperatly, of course. Note the difference in weight, and add 1/2 of that weight difference in the light wing's aileron servo pocket. That should take care of the lateral imbalance. No aileron trim should be needed if you accomplish this step.

As you become more familiar with the flight characteristics, you can start to sneak the CG aft an 1/8" at a time until you get freaked by the pitch sensativity.

As Matt suggested, you will certainly get a "Snake dance" takeoff without the up elevator input at the start of the take-off roll.

Hope your knee heals soon, Matt.
