Were you flying electric or glow planes?

I fly both electric and glow heli and like flying both. So in my opinion if you want to stay electric then stay that way if you want to get into glow then go for it just decide what size you want and go for it. Since you are flying a small electric you could go into any size you want and with new heli's like the Trex 700on the market now you have almost no limitation as to what you can get for very nice and capable heli.

Of coarse the price is all relative yeah the batteries are more expensive up front but after some time the price of fuel you put through the heli will catch up with the price of the batteries.

Sorry if I wasn't much help but it is a very hard question to answer.
