That's pretty good, I must say.

The mess factor is, well, with glow engines, is part of the hobby and, of course, cannot be avoided to have good, smooth, and long lasting engines. The cost difference, is, of course, a significant factor. Glow engines are much less expensive than gasoline powered engines. Added plus is that the glow engines are easier to learn with. Tuning is fairly simple.

Setup for glow is pretty straight forward but with gasoline, it can be a tad bit more difficult.

With gasoline, you need a separate battery to provide for ignition and have to consider the inteference caused by gasoline powerd ignition systems.

For a beginner, glow is more beneficial - easier - to set up than a gasoline engine.
