Not picking on you specifically, but as long as fliers employ a system that allows them to acheive a similiar level of safety with similiar convenience of an arming plug (so they'ed actually use their system) then let them use what they want.

It's when you see fliers messing about with their planes with batteries plugged in and the ESC just waiting for the right signal to fire things up is when I start to cringe. The good 'ol "TX is off so it can't start up" way of thinking scares me. Yep, it's probably true 99.99% of the time but is it a necessary risk worth taking? I'd be surprised if sombody ever would leave an IC plane unattended and running in the pits, even if the TX was off and the failsafe set to "idle" but some haven't a 2nd thought about leaving an electric unattended with the batteries plugged in.

Oh,, no external arming plug = no international F3A competition for you
