[NSRCA-discussion] Arming Device for electric airplanes

Wed Sep 26 13:58:05 AKDT 2018

Scott A, Everything that needs to be said about electric has been said but
your noting the Loss of signal issue reminded me of a very hazardous
situation that happened to me many, many years ago when electric was just
becoming popular, some might learn from it as follows:  

Switched the Fail Safe program in the transmitter from one plane to another,
reset the "loss of signal" throws on all surfaces.and..forgot to "check" the
throttle which was reversed for plane #2.all other programming was perfect.

Landed the plane taxied to the pit area, plane stopped, throttle in "off"
position, electric motor was "off", reaching down to disconnect the battery
but.as I leaned down still holding the transmitter and not holding the
plane, reached over and..

"Turned the Transmitter OFF First"  the plane went into full throttle,
luckily no one was in front of it, left the ground and headed for the
parking lot.lot's of yelling and no one luckily was hurt and the plane
luckily crashed into a pole in the parking area destroying itself..

THIS HAPPENED WAY BACK IN THE EARLY DAYS OF ELECTRIC...I then devised my own
external arming plug and never had a problem again with uninitiated
activated power.  

"If it can happen, it will"...arming plugs are a help along with having a
great respect for the dangerous potential of electric goes a long way toward
safe electric flying.

Right from the AMA competition guide.

At no time will a model be left unrestrained or unattended while running or
with the electric motor power circuit(s) physically connected unless the
model is on the runway.

All models that have the capability of Fail Safe in the radio shall have the
throttle set to Fail Safe in a way that the motor/engine comes to a complete
stop or a minimum idle if it were to lose signal from the transmitter.

Okay how about the FAi pilot who accidentally advanced his throttle in the
pits at a June contest and destroyed the entire back end of an Oxai ?

Only by grace was no one injured

So you want to require an arming device based on a sport flyers stupidity.

This is real experience.  About 3-4 years ago I was getting ready to fly
with another friend.  Both of our planes were already in the pits and we
just were talking before starting the day.  A pilot came with an electric
plane and parked between us.  He left it there and decided that he needs to
go and get something.  About a minute later his plane came to live suddenly
and took us from the pits.  It starting to do an small loop and was coming
directly toward us.  It was so fast that my friend said "take cover". We
were lucky that the plane crashed in front of us and there were no more
pilots flying or around.  It was so fast that I didn't have time to move an
inch and could have hit us easily.  The plane didn't have an arming switch
outside so there was no way for us to know if was armed.  The owner came and
we never were able to figure out what really happened.   

I think makes sense to put together a formal request that will require
external disconnect outside the electric powered planes.  It is easy to
justify since is already a requirement of the National Electrical Code and
OSHA.  Anyone out there wants to put together a draft.  I will help to
signed since I am a CD.  

!Gone Flying!

Rule says you must disarm the plane before bringing into the pits, does not
say how.  That can mean take off canopy and unplug.  I've moved to using a
Jeti anti-spark bullet in-line on the red side of the battery-esc connection
with the bullet routed to the outside of the plane.  Quick, simple,
foolproof.  Anti-spark prevents carbon buildup on the bullets.

Guys, what is the current status of arming devices in NSRCA for you electric
airplanes?  Does anyone know what the AMA says about arming devices -- I
can't find my way around the new web site yet, and this is the easy way out!
