[NSRCA-dist7] Rules proposals

[Bill's Email]

  I don't fly all that much pattern, but in all my planes I use the 
arming switch made by Emcotec. It does not provide a physical break as 
required by the proposed rule, but it does provide protection. When the 
magnetic plug is out, the system is ready to be armed. If the radio is 
off it will not arm until the ESC gets a signal from the RX. Put the 
plug in and the circuit is broken between the battery and motor/ESC.

I confirmed with Emcotec that the system fails in a safe mode. If the 
motor is armed and running and the Emcotec Saftey Power Switch fails, it 
shuts off power. If it fails when the plug is in, it does not turn on 
when the plug is removed. In my mind this is as safe, if not safer, than 
a plug that must be plugged in to arm the system.

My 1 cents worth (since I have not been flying pattern for 25 years)  ;~}
