RE: make some smoke
usually with a glow engine the smoke is not very dense or long lasting at all and the added weight and wing loading compromise greatly flying characteristics. smoke is best left for the gassers but you can use any pump setup and just tap the muffler as close to the engine exhaust port as possible and set the flow rate for best smoke performance. depending on the engine name brand there are different suggestions as to what is the best type setup.
