| I would recommend the ringed version, IMHO the ringed engine is better than the ABC with regards to smoother running in the mid range ie hovering power setting. This of course assuming everything else is equal. I do think that the ABC has slightly better peak power, but that is not what heli engines need. Also at the end of each flying year, I change the piston ring which seems to freshen up the engine, a simple and cheap option.
