Question
Motor for Herr Cessna 180

I just got a used Herr Engineering Cessna 180 Skywagon. The plane spans about 42 Inches and the finished airframe weighs 12 oz. I read somewhere that a 370 class motor would be about as big as I would want to go. It has to turn a smaller prop around 7 -8 inch. What motor would you guys recommend for it. I read, i think that around 100 -150 watts per lb. So I am thinking a 200 -250 wat power set up.

thanks

That plane is designed for an .049 nitro. A quote from Sig: "And when powered by a nitro burning performance .061, you'll be able to fly this bird in ways the real Cessna people would never even have considered trying."

200 - 250 watts is more like a 480 to .10 equivalent. A motor like this is all you need:

I am not sure how much power the .061 produced but that will give you much more power than the .049.

Here is another thread with a good discussion on a similar plane:

reading that will save a lot of duplicate effort.
