I fly nitro however I did try gas but I didn't like the smell of gasoline. With that said I would learn on electric and then go gas or nitro. Electrics are easy to use and are less stressful because they make little noise. Don't be fooled by size since that is relative. I flew both; 30, 60 and 90 size helicopters and the bigger they got the further I could fly from myself. Get yourself an electric 4 channel semi trainer from Park Zone and you will do just fine.
