What would be a better engine to run a ringed OS .32 or and ABC version and why?
Thanks!

The ringed engine will produce less power than the ABC, while the ABC will also run in faster. The benefit of the ringed design is that it is more tolerant of lean runs than the ABC, witness that all the OS engines from the 50 up and the YS heli engines are all ringed >> reliability is paramount on a heli. I would sacrifice the power of the ABC for the additional tolerance of the ringed engines

Ringed engines also have a different power band than ABC. The torque tends to be more even from a ringed engine. The torque for an ABC definatly peaks out near the top of the RPM range...

Or so I have read...
