RE: What would a gas engine be compared to a glow
I just assembled a Great Planes Giant Big Stick, it calls for an OS 180 2 stroke, I installed a DLE 30, it seems to be about right. Based on that I'd say that an OS 120 2 stroke was about equivalent to a DLE 20 and an OS 180 2 stroke equivalent to a DLE 30. Hope this helps.
