ah ha...thanks for setting me straight. The 20 is 20cc's. I stand corrected, or better educated
That sounds like it might be decent, although once you've had the power of a strong glow it's tough to find a gasser to compare in this size range. It seems you'd almost have to go the 40-50cc range to come close the Moki glow's. How does that 20 compare with the glows?
I admire the original poster for scratching out a Goldberg Sukhoi. I bet that's going to be one awesome plane. Thanks again Johnny. Take care.

For MorePower, ..how about a ZDZ40, they are a bit less pricey then the BME's, and from what I've read, very powerful for a 40cc engine.
