Would this motor be comaparable in power to a 46FX. I am looking at it for my CMPro Lancair which reportedly will come in around 6 to 6.5 lbs???
No. It would be equal to a good .32 to .36 two-stroke.
Every few years, a bunch of newbies come through that insist on believing fairty tales, such as parity in power between equal displacement two and four-stroke glow engines. Ain't possible, folks. Not if both two and four-stroke examples are not supercharged and both are running the same amount of nitro @ 15% or less.
This is not to say that you or other people would not be happy with how their models flew when powered by a four-stroke glow engine with a displacement equal to the highest recommended two-stroke displacement. Power is a subjective topic and can vary from one individual to another. But let's get real and not try to say that both types of engines produce the same amount of power when at the same displacement. No. No one said they were, but that is what is being implied under the text we are seeing.
