I currently fly both..

Started out in nitro then moved to gas for a short bit.. Then, got a wild hair and sold off most of my big nitro/gas stuff and went to solid parkflyers, basically.. While it was really fun at first, I was mainly flying in my backyard so parkies were great, then I started getting more time to go to the club field and found myself wishing I had the larger stuff again.. Sooo.. one day I came home and started one of my .46 fx's I had sitting around.. Now I fly both again and boy is it nice to have both..

I can toss up a parkie and go fly for a bit.. Or I can load up the grocery getter and fly the bigger stuff..

If cost were equal, I would be probably fly only electric.. Although, I would miss the sound, a little.
