I've also learned that when anything is larger than a 1.50 cu four stroke equivalent, a gas engine is the best choice.
But I'm still perplexed by net power ... for example power-wise speaking, is a 26 cc gas engines as powerful as a 1.50 cu alcohol fuel engine?
I guess the other way to do a conversion is weight. A 9-12 pound model is a 26cc gas? A 12-16 a 30cc gas? etc. Still learning that.
Great tips, ggraham500.
In order to make it easier for some of us to compare apples and pears, I have put together the attached comparison chart.
Please note that this is not a comparison of power, but only one of engine displacement volumes.
Having the same displacement volume, a two-stroke nitromethane engine will produce more power than a two-stroke gasoline engine....and weighting less.
