Guys
Come on :-)
That's not what is being described
A pull-pin or break-wire or mercury switch is A COMPONENT which (when used in
and of itself) is a shitty way to light a motor whether it's in the air or on
the ground. I wouldn't sign off on any project which used these ignition
methods anyhow (even before the rules)
And, how many times have we yelled at people out on the range when it was
closed? In fact, why would people be out on the range WITHOUT an HPR flier in
the first place?
We already practice these rules, and now we will enforce them
