That muffler would be the big hang up in my opinion.  Sounds more like a speed engine.  DOC Holliday

What class or event does a 29 fit into?

 HMMM   That sure looks like the same AC .29 in the Speed section. The forward lugs give it away.

Is the same base of the AC.29 B speed case .
 But I can remove the front lugs,  move the  exhaust 45 degrees, the crackshaft is also short ..
can be use in any combat class with different prop and in R/C combat  B open too.

  According to that print, as I read it, there is no way to move that muffler 45 degrees. The exhaust port is in a fixed position on the rear of the crankcase. Or did I miss something? Interesting engine though.

Alberto - I don't quite understand. For instance, you couldn't use it in 15 or 21 combat? I suppose my question should be What is the 29 limit combat class or event? Regards I.R. (I'm talking C/L of course).
