what would be the compasrison of a OS eng ine verse the RCV 58. Either 2 stroke or 4 stroke. I am tring to select a good engine for a Kyosho AT-6 texan. WHat engine has the same or close to same power output.
Thanks

Hello!
I have flown many of the Kyosho warbirds and many of them has been powered with the Saito .56 fourstroke and a 12x6 APC prop.
This I think is a good engine fot these airplanes.
If you choose a twostroke .... any .40-50 engine would be good using APC props between 11x6 and 12x6.
I have flown the Kyosho spitfire witha MVVS.40 engine with the super quiet MVVS silencer and a 11x6 APC prop and it was a very plesant aircraft to fly much quieter than any fourstoke with very low idle rpm ( 1900-2000 rpm).

Regards!

AV, your question is a little vague, I've never owned an OS so I can't comment but I do own an RCV .58 CD, simply said it turns a 13x6 at 9,000 rpm and does so smoothly and fairly quietly. It was $189.00.
