thought i read some place that the ringmaster was legal in that class  RAD

I'm not management, just a regular customer since flying for Marvin Denny in 2005.
The engines are the Fox 35 Stunt, Brodak 25 and OS LA 25.
Airplanes are the Shoestring, Buster, Cosmic Wind, Flite Streak, and Lightning Streak.
The fuel tank is a 2-ounce plastic tank filled with house 10% fuel. No shutoffs.
Laps have changed from time to time, 70 & 140 and sometimes 100 & 200.  Either length works OK with 2 ounces (for me anyway).

Personally, I favor the Brodak Lightning Streak because you can build it with common off-the-shelf wood, no special LE & TE shapes.  I was building a Cosmic Wind in April of 2006 when the rules change allowing Streaks was announced.  I instantly abandoned the Wind and built two Streaks which I still have today.

My Streaks were originally done in plain clear dope.  Then I bought an air brush and used them as my first two practice painting subjects.  Not masterpieces but apprentice work.

...Super Slow Rat should have been Goldberg/flight streak/ringmaster planes so we could unify all the Foxberg/slow rat events ...

I believe SSR allows all those plane designs and all the above listed engines.  It's meant to be very inclusive.

That's why there are different events. If you're not happy with a national event like SSR, then you or your club can change or create events to suit local wants and needs. If we unify all the events, are you willing to give up your event for the greater good? But we digress...
