Pitts S-1 weight and balance
I have an older Pitts S-1 project I an trying to finish. It has
Sparcraft 4 aileron wings. The old plans I have do not show the CG range. Does anyone flying a Pitts like this know what the CG range should be? Thanks!

From the "Pitts S-1S Airplane Flight Manual"
Datum is 65.06 inches forward of the lower wing leading edge. Most forward limit: FS 64.00 (17.9% MAC) at 1115 lbs or less. Most forward at max gross weight: FS 65.00 (20.8% MAC) at 1150 lbs. Most rearward at gross weight: FS 66.00 (23.7% MAC) at 1150 lbs. Most rearward limit: FS 67.00 (26.6% MAC) at 970 lbs. BJC "wallyairplanefan" wrote in message om...

Hey thanks Byron! I think I can use this!
I will try to calculate where the MAC is on mine since I think the fuselage is a little longer on the S-1S than my S-1C Wally "Byron J.
