I think with the new electric rigs on the market today one could go either way, Its just a matter of preferance. I would go to a field and observe gas, nito and electric and make a decision based on that. I prefer the nitro for smaller models and gas for the big birds however I would use electric only in one instance.. A Glider. Oh..may be another idea for electric would to hook up an robot mower to keep the flying field trimmed down
I am sure flying electrics inside would be fun for some but to me I just like to be outdoors!
