[NSRCA-discussion] Arming Switch

[Scott Smith]

Agreed…caller is responsible for the safety/restraint of the plane and keeping others away from the prop until disarmed.  Procedures should be reviewed in pilot’s meeting.

 

Maybe in addition to a ready box, we designate a “shutdown box” ahead of the pit area where callers return to and wait for the owner to disarm.

My caller’s always maintain control of my airplane until I come over to disarm it. It goes with the gig. If I’m using a new caller, all of that’s covered before we start. Chris Moon and I called for each other all through the Nats and we never called for each other before that. As it turns out, we have identical routines and from what I’ve seen, most guys have routines similar to ours.

 

As soon as I land, my left thumb goes on top of the throttle stick at the base pinning it to low throttle which means brake on for me and stays there until I get to my plane to disarm it. When I’m initiating or disarming my plane, I don’t and won’t respond to anyone trying to engage me in conversation. My order for initializing is Tx, Rx, then batteries in that order. When I’m disarming, it’s batteries, Rx and Tx in that order. It’s all about safe practices and routine. I’ve had no mishaps in 8 years in electric and won’t have any mishaps. 

 

In short, I don’t want or need a disarming plug. Those that do will probably figure out some other way to hurt themselves or someone else.

Just how many airplanes have we seen fly out of caller's hands at contests?  Is this a widespread problem, or just isolated to a couple contests?   Why can't the caller maintain positive control of the airplane until the owner gets over to disconnect the battery?  If the caller and/or pilot are that distracted after a flight, what is to keep them from forgetting to removing the arming plug?  

I think this is a solution wandering around looking for a problem.  If you can't remember to disconnect your battery as soon as possible after a flight and to only connect it just prior to flight then you won't remember to use your arming plug to perform the same functions.

Ok, sounds like an EMI problem with the ESC. Some sort of stray electrical noise is coupling onto the ESC (possibly through the throttle input). 

 

Regardless, disconnecting the battery or arming plug would have prevented the situation. Point taken.

Myself, among others witnessed a speed control (rx off) turn on violently during an interesting test in which the pilot showed us what a ringing cell phone can do when placed next to an armed speed control.  No, I don't know the brand of ESC.
