With those tail booms out the back and the servos mounted that far aft, I had a feeling I would need to add some weight. It ended up being about 10-12 oz., as it turns out. I am using one 6V battery, stowed under the forward fuel tank. The rest of the weight is sitting on top of the firewall/engine mount box up front.

If I had thought ahead more, I could have mounted the elevator and rudder servos toward the front of the booms and routed some pushrods inside the booms to help alleviate the balancing issue, but oh well... I should have enough power regardless.

This Sunday is the set date for the maiden flight. Wish me luck...
