Another thing to consider with this particular bird is the gas tank orientation. My first attempt was with a Moki 1.80. To make a long story short I was going to have to pump it and do the plumbing thing(funny I bocked at this since I'm a plumber). It's currently being retro'd to a gasser for convenience and reliability.
In no way am I saying glow is not reliable it's just that a gas engine seems to be a better fit for this plane given the logistics of the set up and, like Lou said it sure is a lot cleaner and cheaper in the long run.
If you have it just sitting there, I'd go gas in a heart beat. Just my .02.
Best of luck which ever you decide.
