CG Balancing
Balancing the Pitts is very important, you might need to use weight depending
on the servos and engine that you use. Start out with the balance point at 5”. This
balance point is a safe place for you to fly the Pitts.. As you get comfortable you can
move the CG back further. The 33% point is 6.22” The further back you move the CG
the more wild the aerobatics will become, BUT the more unstable the Pitts will become
The CG is measured on the top wing At the center of the wing measure back 5” and
place a mark. Measure back 6.2” and make another mark. Using two fingers under the
bottom side of the top wing, lift the plane. It should hang level or slightly nose down. At
the 5” in mark it will be nose heavy but will be really stable on the first flight. The Pitts
will probably need weight in the tail to get it back to 6.22”.
