RCadvisor’s model airplane design contest ends in one week. $175 in R/C goodies or $75 in cash is not too shabby, so get busy and enter your best designs! More information is in the forums.

From what I’ve seen in other contests, I expect most entries to come in five minutes before midnight on the day of the deadline. I’m okay with that. The downside of that strategy is that you won’t have much time to receive feedback and make revisions.
