I have been getting the itch to get back into old school pattern flying, I joined the CPA and can't find much on their rules. I assume that a .61 is still the max engine size that can be run but O.S. Max does not make a .61 engine anymore, what are you guys running for engines? I see Rossi is still in business and making a .61 but I am a big O.S. Max fan.

Many years ago I built a Trouble Maker, does the Kraft hat give away the age of this photo?

After building big scale stuff it's time to take a break and build a pattern plane!
