electrics have a weight disadvantage,try to hover for any length of time with an electric.out in out though there are a lot of things contributing to the choices of either gas or electric,size of field,noise limitations,and namely cost.as for me i have flown both and like most here love the smell of nitro in the morning............you either invest in electric equipment or nitro,about half of the equipment is interchangeable.for learning to fly just my opinion but i think a gas 40 size trainer would be the best choice as far as time in learning goes.
