RE: First time hobbyist.
I learned to fly with an electric. As Nathan says, it did take me a few additional sessions with my instructor because of battery charging time, but I don't think it took an extreme amount of extra time. I'm kind of glad I did start with electric. I have a better understanding of battery packs and the best way to maintain them.
When I moved to glow, I found I had a whole new set of challanges to cope with. My least favorite is cleaning everything up at the end of the day. Man, glow fuel makes a mess! It was nice to take my electric from the runway to the truck without having to spend all the time cleaning up. I could get an extra few flights in before packing up with my electric versus glow.
I fly both now. I admit, I fly the glow more than the electric, but only because I like the smell and sound. You'll find it can be rather addicting. What you fly can also depend on where you fly. Either way, hook up with a club and have an instructor available before you choose. You don't want to make a decision to purchase a plane and find that it really isn't what you need to begin with. The wealth of knowledge that an instructor will provide will do nothing more than increase the return of your investment, as well as increase the fun.
Oh, by the way, either way you go it isn't cheap! Don't expect it to be. You would be misleading yourself if you intended on doing it correctly, and for any length of time.
Welcome to this hobby and most of all..........have fun with it.
