Conversion
 

Can someone tell me how a OS, Enya, or Saito 4 stroke would compare to one of the big Gas engines? I have a airplane that calls for a 40cc gas engine and was wandering what size Nitro 4 stroke would be compareable in power. Are they dirctly compareable? Say the OS 240 Gemini.

Thanks
Doug

They are pretty close in power but the gas engine is more cost effective unless you already have the Gemini.

Enjoy,

I am getting into gas as we speak so take this with a grain of salt... But doing the conversion isn't a 240 FS comparable 160 2-stroke powerwise?? 40cc = 2.44 ci Now you would need a 2.44 or so 2 cycle glow angine (if they make them) or like a 4 ci 4-stroke (if they make them)... If you can afford the engine/fuel go for it... I am personnaly switching to gas to turn my $2-3.00 methanol flights into $.30 unleaded flights... A 60-70$ Homelite chainsaw and some parts from wackerengines.com and you have a gas engine for $150.00 or less... I don't think you can beat it... Plus I know when I started R/C the guys with a big plane and a gas engine were "cool" :D Am I out to lunch with my conversions?
