I wish I had a throttle kill on my transmitter.
My Pulse 60 has an E Flite 60 with a 15x10 APC and a six cell pack. Very scary.
I have a separate receiver/ servo battery pack and when I switch that off the motor should not come to life, I still disconnect the battery.
I've seen a lot of guys walk with the battery still connected, I hope this will be a wake up for them too.
Tall grass would be a better stop than the fence, I'll bring that up with the other members.
