I am building an LT-40 kit. I have joined the wings and the torque rods are glued on, next step is to install the ailerons.

As the wing sits, it tends to lay with the left wing flat on the table and the right wing up in the air (dihedral). If I push the right wing down flat, it returns back. Obviously the left wing is heavier. I am unsure whether I used more glue on the left, or perhaps some of the wood is a bit bigger. I am installing dedicated aileron servos, so I can trim out any roll effect caused by this. But I just wanted to know if it is better to glue a piece of balsa to the inside of a wing rib to add some weight to that side or just leave it. (Don't want extra weight, its already gonna be close to a lb overweight, with extra servo, epoxy, .46 motor, sturdier landing gear and taildragger hardware, metal pushrods)

Thanks.

Best thing to do is to balance the aircraft laterally.......with the wing attached to the fuslage with the tail plane installed. Just have a helper balance the tail with one finger, you grasp the prop shaft.........then see which wing is heavy. The muffler hanging on the side of the engine can make the airplane heavy to one side also.

Don't forget to have the engine installed with the muffler on when you balance.

Don't worry about individual components, it's the end product you'll need to balance. (The muffler will definitely outweigh the little imbalance of the wing.) And for a trainer, lateral balance isn't usually a very big deal anyway.
