Does anyone use 1cc or 2cc motors for their planes? What kind of planes take these motors? I'm suspecting electric planes which have been converted. Do they work any good?

Wow your last thread titled Magnums was completely removed

Small but not micro 1.5cc is .09cubic inch some motors such as PAW are as small as ,033 and .06 cubic inch and yes they will fly
electric conversions usuallly the equiv of a 400 size electrics lots of ARFS out there also-- built up NOT FOAMIES--
.09 and down are considered 1/2 A size engines they have been around at least 50 years cox is most likely the best known
with the advent of electrics lots of modelers are doing this your best bet is check out the 1/2A site
I have a decathalon which was on electric with a norvel 074 in it flys great martin

09 is considered class A.

That's why you used a Cox 049 in 1/2A freeflight and then removed it and put on an 051 and flew the same plane in ClassA freeflight. Holland hornet made 049/051 and so did Atwood for this very reason. Also fly an 051 in 1/2A speed and if they find out you get disqulified.

What you say is true for the USA, and that is how most of us think of it. However the rest of the world considers 1.5 cc, 09, as 1/2 A. In any case you can talk about engines up to 15's on the 1/2A forum without raising eyebrows.
