Yes, no question about that one. And just because the big dawgs have move to other powerplants besides the OS140RX, does not make this engine any less viable. In the right hands and right airplane weight, it will win at any level of competition.

Good luck with whichever approach you take.

I personally still use 2 stroke powerplants (one of the few remaining diehards I suppose), except mine are gasoline burners.
