I don't see electrics as a replacement for glow or gas(unless you have to), but an additional option that allows you to fly R/C more. I have almost totally giant scale gas, but I also have a Zagi and a Bleriot park flyer.....also, I just did a review for RCU(check it out in this month's issue of RCU Magazine) of the twin engine Aventura III seaplane. What a gas. :-) It gets off the water with ease and really has tons of power with 8 minute flight times. For noise sensitive areas electrics are a great alternative. At our field recently we had an electric fun fly and some of the electrics that showed up were pretty amazing. Including some German high-performance sailplanes that were virtually rockets and fully aerobatic.
