STAUDACHER S260-2
Tom Sinnott with his wife Debbie returning from a contest in 1992 in Burlington Wisconsin.
I was flying a factory Pitts S1-T and looking for a 2 place to fly in Unlimited. I saw a few pix of Jon Staudacher's second aerobatic build after he created his own version of the S1-S Pitts. I bought it on the spot, it way outperformed my Pitts - uplines, rolls, corners Wow! Now I could take my family to contests!
