I'm all gas. (ask anyone) But thats because I've been in the hobby for nearly 30 years, and all of my tools, my equipment and so forth all all geared toward building and flying nitro models.
However, A good friend of mine likes electric models. I do most of his test flying for him. (he is a little older, 68, and his reactions are not that great, and he started late in life, so he never reached a very high skill level ) Anyway, I have really been very impressed with the new elcetric motors and the new lipo batteries.
But switching to electric would be very expensive for me. Buying batteries, chargers, micro servos , smaller airborne equipment and such would be needed. It would be like starting over.
But if you ARE just starting, then it really might be something to consider. They are quieter and can be flown in smaller fields. Someone mentioned that they require lighter winds. I suppose that is true. However, I have flown the Hobby Lobby Mig 15 , ( nearly 100 mph ), in some pretty stiff breezes. So, I think they handle the wind pretty good, at least the faster ones.
