Here's a few more things to avoid saying:

"I sure hope you got a really, really good deal on that radio system!"

"You picked a good week to crash that, Tower Hobbies has them on sale right now."

"That's what happens when you fly with one of those [insert brand of radio here] radios... pieces of junk if you ask me."

"Don't feel alone or anything, four other guys crashed in that same spot earlier today due to radio interference."

"Hey, hold that up for me and I'll take a picture for the web site!"
