A new respect for electric

       Remove this ad - become a site supporter!
I just started Fly electric about year 1/2 ago.
On nov 10 I found out the hard way how much damage thay can do and the result was three hr in the emergency room and got 4 stitches and two weeks off this not a way to take a holiday .
I was seting up a electric mini funtana . I was doing the final setup .
I was on the floor turn on the radio and set the radio down on the end reach in and plug in the battery
I moved back about 6" away from the devil and just about to grab the radio
when the radio fell forward pushing the throttle stick FuLL THROTTLE it wasn't a lucky day for my left hand .
I learned when setting up to remove the prop before doing any set up now.
here are some pics what electric can do .

Stitch's could have been neater but they hold it together. (Your lucky) I don't like getting near any prop as it does not matter what is powering it. They still slice.

I been flying glow and gas for 25 years.
And one thing we don't realize that with electrics that when you plug the
battery in the ESC that not only that it activates the radio and it activates
the motor too.
And with glow or gas motors it's not activated untill you add a glow driver or turn on the ignition system. and I have been doing some reading on electrics and what I hace been finding is there have been more accidents like this because power is instant.

One of the first things we were taught as young engine fitters (slang for aero-engine mechanics) was that a prop is ALWAYS live, does'nt matter if it is on a 65 horse Cub or a Pratt R-2000. The same applies to our models, the damage they can do is obvious. I hope no permanent damage was done to your lunch-hook.

I've cut myself from props at least a dozen times in the past year. It all started with the stupid little electric motors. Not always with the props turning either.

Never with a glow, I have had my fingers rapped when flipping an engine, but never cut.

Electric planes are deceptively quiet.

Hey Guys,

I had a similar incident, that fortunatley did no human damage, only plane damage. I now make sure the throttle is at about 1/2 before I hook up the battery to the esc. I use CCpheonix and they will not arm until the throttle is pulled all the way to idle for a couple of seconds. I haven't had any trouble since. It does put a little more faith in electronics than I'd like but it seems to work for me.

Hmm, Wonder what I can build from that shrapnel?

If you guys are using computer radios you should really look into using the throttle lock function, it's there for that very reason.

I won't even go near my powered on model unless the throttle lock is on in my transmitter. It's too easy to have accidents otherwise.

It's saved my model AND my hands on more than one ocassion!

This is one of the reasons I am not converting holus-bolus to electric. (The other is the high cost of entry). It scare the bejasus out of me that the prop is basically live the minute you plug in the battery. I suppose I could instal a great honking 3pst switch between the motor and the ESC, but one that handles the amps without putting resistance in line would be big, heavy and ugly.

I am leery as hell of something that turns without making significant noise.

Your hand

Sorry to see that you got injured, but prop is prop, as mentioned above it dosen't matter how its getting power from but its turning, and when they turn they reaaaaly turn!, i am slowly getting into electrics, i hope your hand heals up fast and you can get back to regular life style again. Well i'll take that as learning lesson towards electrics....

Best of luck on fast recovery bud...
