The only thing that keeps me away from SPA is you can't run tuned pipes or retracts. the guys with the .91 4 strokes are running away with it. Let me fly my piped UFO and I'll fly it =)

What's that? Sounds like a controversy about engine size in the SPA. I thought the SPA was a brotherhood of like minded old timers that were tired of the changes and controversy's surrounding pattern flying.
