Ah....it's for the big stuff only then!
So....when I see threads where folks are discussing what engine to put in, and one guys says "i'm putting in a Saito 1.80" and is followed up by the next guy "i'm going to put in a g23 or g26 instead", I have to wonder why? Is it like the difference between a 2 stroke and 4 stroke glow?
Or when you get to a certain size it becomes a personal choice? Or do aircraft models specify gas or glow at some point?
There is one fellow at the field I fly at that has a gas engine, it sounds like a chainsaw....seems to have lots of power though.
What about multi-cylinder engines...i've seen them online offering as many as 9 cylinders to a single engine!!!!!
There is a transition zone between 1.2 and 2.1 cu.in where it's more or less a personal choice which type of engine to use.
Some multi-cylinder four stroke glow engines go well above 2.1 cu.in. The Saito FA-450R3D 4.5 cu.in. radial engine is one example.
Some kits designed for 1.2-1.8 cu.in. engines are to lightly built to withstand the pounding of low revving gas engines. Apart from that the choice is yours.
Be warned, some people tend to get quite religious about the pros and cons of gas and glow engines :-)
