How do converted enginesin the like 31-54cc range work in the cold? I only have experience with my glow motors in the colder months(like 35-45 degrees). For example I would say 2 stroke glow motor work pretty well,and my 4-strokes dont like the cold unless they have onboard glow and even then,I dont fly them until it warms up a bit.

So basically what I'm asking is how do these converted gas engines work "compared" to my glow engines?

Thanks guys....
