for sure, a top notch EDF setup is gonna cost more than a used turbine. you can get used, air start turbines for $500 and up. you see them all the time. you can barely get a fan an motor for that much if you go to an e-Dynamax. the batteries are expensive if you go with TP packs, but I've got buddies with between 200 and 300 charges on TP packs and they show no signs of letting up. you just can't beat the sound of a turbine, but I love my EDF's. arguably, you have to be a better pilot to run EDF, or much more conscious of your energy state would be a more correct way of saying it.
