[NSRCA-discussion] Plane thought to be off still alive WAS: Shorting plug with 2.4

Fri Nov 20 15:26:11 AKST 2009

On a note of safety I'd like to share an incident that occurred at our club
recently.

A sport flyer put his foamy down after flying it and took his glow plane out
to fly. He obviously failed to unplug the battery and it being a typical
foamy with a bec, when he throttled up to start his glow plane the foamy in
the pits took off. Luckily no one was injured.

When flying pattern I realize we don't normally have out more than 1 plane
BUT it's getting to the time of year when some of us play with other types
of RC and I just want to remind everyone to always be sure your system is
powered off , somehow. 

Whether you use an arming plug or not is a personal decision. But have a
routine(protocol) in place to be positive everything is unplugged.

We pattern guys are famous for our routines(protocols)  -and that's a good
thing.  I just don't think talking about safety can ever be too much of a
good thing !

Eddie

ANY RF link can fail..and any software can be corrupted.  How safe is safe
enough?  Up to the user for the most part.  I didn't use a shorting plug
with PCM, and don't use it now with 2.4.

Regards,

Dave

I have flown with the shorting plug 4 heck, 3 or 4 years now. My reason for
this discussion hopefully, was to see if with the new 2.4 technology and
binding a receiver to a radio, if it is thought to be necessary anymore. I
don't think it is. Someone would have to pull my hatch, and physically push
the button to bind to my receiver. Any thoughts? Guess I should have workded
it a lil different. 

I happen to use the idle up function on the 10G Anthony, with the throttle
trim all the way down

. And it is set to be adjustable on the slider if necessary. 

Thanks!!!

 Hi Dave,
   Like the throttle up idea. Wasn't sure how annoying the brake/deadstick
switch would be we is why I called it an experiment. One of those things I
will have to try. Might be best to have the brake on a seperate switch.

Jim,

2m stuff AXI 5330 F3A w/ CC HV 85

Chris,

 The only down side to the shorting plug is weight and an extra connection
point. It would be nice to be safely ready to fly without having to mess
with the canopy.

Pos 0 - brake

Pos 1 - slowest idle

Pos 2 - +300 RPM idle for better stall turns and spin entries

If you are considering toggling between low idle and brake on/off in the
air..I'd have it on a different switch than your "kill" switch..lest you
find yourself deadsticking because of an errant switch flip.

 Hi Chris,

     Never used one but like the idea. I use the throttle cut function on
the SD-10. It is set to a switch so when not flying my TX is always in the
throttle cut position. When my caller puts the plane down I flip the switch
and my motor starts at the lowest possible idle with the trim centered. If I
need to adjust my idle I can do it with the trim..
    Since all of the switches are 3 position my next experiment is to use
the idle up function to set the brake on the middle switch position. 
    Has the E-motion flown yet?

Anthony

What are your thoughts on using a shorting plug with the 2.4 systems. I
always used them before, but now with my new system, I'm not sure it's
necessary. 

Thanks!
