Park fliers are, as individuals, just one of the big fads, although a fair amount will stay for many years.
I just love when an ol timer thinks things are going to go back to the way it used to be, "back in my day".
Parkflyers going away? HA! Electrics going away? HA! Yeah people want to go back to paying $15 a gallon of fuel when the quality of the batteries goes up and the price goes down.
Parkflyers are going NOWHERE Hoss. Right now it's the dominant market and it will only grow. Like I said, I'll personally make sure of that little known fact.
