Just now recalled one of the first ARF fliers I ever saw, many years ago. Never had seen the guy before or since. He could take off & land (barely) and repeatedly would climb up high, nose over & gun it. Swooping straight down at full bore and YANKING full up elevator at the last second. Somebody told him he had better ease off on that, but he would not take heed.
I mentioned to my buddy to keep watching because something funny was going to happen. Well, I'll leave it to your imagination as to what happened on the fifth or sixth time he performed his only "stunt." The kid got all ballistic yelling about how "something was wrong with that airplane." How he was going straight to the hobby shop & get his money back!
I looked over at my buddy and said " I told you something funny was going happen."
