[NSRCA-discussion] Arming Device for electric airplanes

Wed Sep 26 09:11:39 AKDT 2018

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 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.

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.

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.

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.
