BTW, very often we shoot ourselves down.
We had a case of that recently.
A newbie walked onto the field with his "anyone can fly it RTF/ARF" and threw it into the air. Flew around a bit and WHAM, straight in. Turned out somebody had turned on in the pits.
Even though at our field, it is posted that you may NOT fly there unless you've been certified, we frequently have newbies show up...
More often than not kids with their fathers arrive, who bring in a Parkflyer plane newly purchased from the local LHS.
They switch them on w/o regard to frequencies.
Since they fly these off the flight lines, they seem to assume that those posted rules and regulations do not apply to them.
Aargh!
