But sometimes it’s not stupidity that causes bad things to happen; it’s <i>ignorance</i>. There IS a difference: stupidity is when you KNOW something is wrong and you do it anyway. Ignorance is when you simply don’t know what wrong (or right) is. <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Since I’m an AMA Instructor pilot, I see a lot of “new” people coming into our hobby. Many of them have a little electric airplane and they think it’s perfectly “safe” because it’s small and it’s powered by an electric motor. I tell them that in reality, this is not the case because of the fact that an electric motor can start spinning the prop VERY quickly and without any warning. Even a little one has a fair amount of power. I tell them to treat an electric power system the same way that you should treat a gun: It’s ALWAYS loaded (even when you think it isn’t). If you look at them this way, you will help to <i>prevent</i> accidents. At least that’s my hope.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I’ve seen people put their hands in the prop arc when they connect the battery in an electric plane. Does this mean they’re stupid? Maybe but maybe not. When I say: “did you ever think of what might happen if the motor suddenly started spinning when you connected the battery?” They usually flinch and stop what they’re doing. “Uh, no” is the typical answer. “Why, could that actually happen?” Of course we know that the speed controller needs to see a low throttle condition before it will arm itself so it’s extremely unlikely that this will happen but the reality is that it <i>could</i> and if you just develop good habits (restrain the model and keep your hands and fingers clear of the prop when you connect the battery) you won’t put yourself in harm’s way. Once I inform them of this they are now fully qualified to become stupid.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Here's something to think about: you’re setting up an electric model to fly with a buddy-box system. Assume that the airplane is trimmed out and flies safely with the Master/Instructor transmitter. In other words the throttle control works properly, the fail-safe is set up correctly, etc. When the buddy box is first connected and you’re making sure that it works properly (you need to do this before you fly with it) what might happen if you pull the trainer switch on the Master transmitter? Here’s a hint: is the throttle stick on the student transmitter in the low position AND is the throttle channel configured to operate in the correct direction? Remember, the model is “armed” because it was powered up with the master transmitter having its throttle set to the lowest position. Yeah, it could and DID happen to someone that I know. They had to put stitches into one of his arm muscles to patch him up and this was caused by a relatively small (30-inch wingspan) electric model. It took less than a second and it was a complete surprise. I wouldn’t call him stupid, he just didn’t realize what could (and did) happen.<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>An arming plug simply arms the motor. I don’t think it’s a bad idea to use/require one but I don’t think it’s going to make things a lot safer. If you still do something stupid or ignorant when the airplane is “armed” bad things can and probably will happen. The odds always favor Murphy. <span style='font-family:"Segoe UI Emoji",sans-serif'>😊</span><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>John Pavlick<o:p></o:p></p><p class=MsoNormal>Cell: 203-417-4971<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><img width=90 height=39 style='width:.9375in;height:.4062in' id="Picture_x0020_1" src="cid:image001.png@01D455F3.009362E0" alt=idslogo2><o:p></o:p></p><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Impact",sans-serif'>Integrated Development Services</span><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b>From:</b> NSRCA-discussion <nsrca-discussion-bounces@lists.nsrca.org> <b>On Behalf Of </b>Phil Spelt via NSRCA-discussion<br><b>Sent:</b> Wednesday, September 26, 2018 1:02 PM<br><b>To:</b> Joe Lachowski <jlachow@hotmail.com>; General pattern discussion <nsrca-discussion@lists.nsrca.org><br><b>Subject:</b> Re: [NSRCA-discussion] Arming Device for electric airplanes<o:p></o:p></p></div></div><p class=MsoNormal><o:p> </o:p></p><p><span style='font-size:12.0pt;font-family:"Helvetica",sans-serif;color:#333333'>No!!

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.
