PAW 29 and PAW have very simple R/C carbs.  Given the right fuel, like Technics D1000 for running in and D2000 for general use, the carbs throttle well and hold settings even though they seem very simplistic compared with a Glow carb.   I also have a very old PAW19 which I converted to R/C with PAWs own carb  in 1980.  I also have just bought a PAW 55 R/C BR which is a honey of an engine, jiust run it in.   My PAW29 is awaiting a 35 liner and piston so I can put it in 60-65 " span  sports R/C planes.  
I find Irvine and Modern OS carbs on glows a little more precise but am well content to stay with PAW carbs.
