I have had a brain fart or two. The most recent one I can recall is when I fired up my plane and had the Rx on, but forgot to turn on the Tx (I know, duh......I am sure I will hear it about this one). The plane fired up at about half throttle, and leaped forward. Of course, I could kill it easily with the external switch, but it certainly got my attention. I did, of course, have my plane properly restrained before I started it up, so it didn't go far, but here is another case of following safety protocol paid off, with both the external switch, and the tail restraint.
