JMO, but whatever someone else decides to run is fine with me...it's a hobby...why should I give a crap about what somebody else wants to run? (there have been many "Great Debates" in all of our local clubs about this...)
I have room in my life for both "Nitro" and Electric power...got some of each...airplanes and ground pounders...but I tend to gravitate to the fuel burners...

The Electrics are great! BUT they just ain't got no "Soul" ya know?! Each Nitro engine / pipe combination has it's own Voice...it's own personality, if you will, (idiocynchrosies? sp? ) and the bark, or wail, or growl, whichever, is just not present with an electric powered anything...
FWIW flying an electric powered large airplane is cool and all, but the lack of noise feed-back takes some getting used to...same w/ cars too I suppose...when there are other vehicles around, it's more difficult to follow exactly where yours is. (especially if your plane gets lost in the fog...no noise to help locate it! so you fly by instinct )

I've been a Slot Racer too...not the plastic toys, but the scratch built "Pro Level" stuff on 8 lane routed wood tracks...and they are all (of course ) electric...
When I got back into the R/C hobby about 15 years ago, after a 10 year hiatus, it was w/ electric power...(mainly because of my slot car experience )
Most of the guys in the clubs looked at me funny because electric powered R/C aircraft, at that time (late 90's ) were so far below anything fuel burning....but it was the challenge to fly with heavy Ni-Cd's and brushed motors that made it even more interesting.

The brushless motors and Li-Po batteries have made the R/C world a very different place...but it's all good, aye?!
