[NSRCA-discussion] Arming Device for electric airplanes

Wed Sep 26 10:00:11 AKDT 2018

What are thoughts of the Castle  Safe lock.
My thoughts are:ProsAdds a layer of protection independant of the transmitter.
ConsPassive device in that the key must be inserted to prevent/stop the esc from being armed. It does not break the power circuit to the esc/motor. It only actives an electronic switch in the esc.
An active arming device pysically disconnects the power to the esc, such as an arm-safe brand type of device.
I have used both and still had unintended power bursts while a caller carried the plane to the flight line.
My latest strategy is the Castle Arm lock is to test it before relying on it. Only rely on it in preparing for immediate flight and carrying to pits after landing. Batteries disconnected/removed any other time.

Matt, I whole-heartedly concur.  I have too many scars on my hands and arms from doing unsafe things around model airplanes.  As someone else said in this thread, everyone will do something careless or "stupid" and risk injury.  External disarming is merely an additional, almost fool-proof, layer of safety.

I for one am a proponent for having the ability to disarm & arm the aircraft externally. I have personally witnessed too many close calls in and out of pattern, and to me it is not worth the risk. I also feel relying on a mix, or program on a tx is not a valid solution or option. It is more likely that a computer is going to fail, rather than a mechanical means. The miniscule amount of weight a simple arming switch carries is worth the safety aspect in my mind. 

My .02 cents.

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

 Subject: Re: [NSRCA-discussion] Arming Device for electric airplanes 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.

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.

 Subject: [NSRCA-discussion] Arming Device for electric airplanes 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!  lol
