I'll mention this later, but in the small chance billberry isn't doing this, I found it useful to individually weigh each sheet of balsa, (on a digital postal scale), and put the heavier pieces on the left wing to counteract the off-center weight of the sidemounted engine. I also did this with the spars. Using this method, I didn't have any problem laterally balancing the Simla. In fact, I many have, (can't remember), put TOO MANY of the heavier pieces on that side, and had to add just a little to the right tip.
