Good luck with the gas setup. There are just a few things to keep in mind. first, with gas, there is alot less stuff to haul around. Field equipment is as simple as fueling system, plug wrench, spare plug and thats it.
One thing to keep in mind is that gasoline fumes are much worse than glow fuel so a good sealed fuel container is important for me. Otherwise your car will smell like gas. I'm running a 46cc and I use a one gallon container and is plenty adequate. I usually have 5 flights each day and fill the container every fith or sixth time heading out to the field. I use one like this and with it's o-ringed fittings it keeps fumes to a minimum.
Another concern is securing the plane during startup. There are all kinds of contraptions for this but I use a tiedown strap around the tail.
All in all you will find gas is much easier and less of an hastle than glow. Have fun and be safe!
