Preferred Code License for FRC?

[What?ItWorked?]

Hi, everyone
The programmers at Team 53 hit a bit of a wall when someone submitted a code licensing issue to our GitHub organization. We don't actually have any licenses with our code, meaning it's just under the github TOS. We like GPL v3, especially the clause about only using code on hardware with modifiable software, and the no patent claim clause, but it doesn't have a "no commercial use" clause, which we would like. Does anyone else have suggestions for a software license with a no commercial use clause?
