Air Whistles? Anybody?
Not wanting to spend 16.99 on a whistle I went down to the toy store and bought a couple for $3. One is a plain old tin whistle and the other one is kinda funny (can't really describe it). I zip tied them on to a piece of plastic and have the on the lower front of the Knife. I'll let you know if they whistle!
I'm kind of excited to check it out. I'm not going to tell the boys at the field. If it actually whistles it will be fun to fly and speculate on it.
