I used to feel the same way when I flew gas but it was just how I perceived electric. I am now flying all electric and just sold off the last of my gas stuff. I can fly non stop all day with planes that are every bit as powerful as any glow plane I ever owned. I was at the field today and there was a guy with a glow plane troubleshooting his engine I pulled out my 50" brushless electric plane and rolled it on the ground for 3 or so feet and launched vertical till it was tiny then pulled back the throttle to 1/2 and proceeded to fly some aerobatics. The guy took a break from his engine and came over to probe for info on my electrics. I wouldn't be suprised if the next time I saw him he had an electric.

I think that there may be advantages to glow but power and flight time are not two of them. I would say that electrics can be more expensive to get into and there is a steeper learning curve figuring out the best batteries/motor/gearbox for a given plane.

The other misconception about electrics is that they are all small lightweight things that can't be flown in the wind. This is because most of the major manufactuers have not yet built larger electric specific planes so for your larger planes you have to either know who makes them, convert a glow plane or scratch build. Here are some good sources for larger electric kits/ARF's

Don't get me wrong I am a gas engine fanatic when it comes to other things, my garage is full of old riding lawnmowers, trimmers, snowblowers, go karts, quads, scooters, and so on, but when it comes to flying RC planes I just feel more satisfied after a day of flying electrics in fact so much so that I have become an electric evangelist(as you have probably noticed).
