Although i am increasingly using eye protection when playing around, I have a fairly powerful electric (by my standards) I've built now. Playing around on Sunday by testing it in the basement as I held its fuse, the prop was not attached properly to the shaft and flew off. Well, as luck would have it, my ear took the brunt and I have a 2 inch long cut starting on my cheek and going into the ear. It didn't bleed that badly, but it could have been an eye!

So my lessons are: eye protection is good, props can indeed cause real damage (and this is only a 200W plane), and be careful when testing indoors, keeping the naughty bits as far away as possible.

JW, Iam glad you're OK! That could have been a lot worse.

There is an old, corny army saying:

STAY ALERT -- STAY ALIVE!!

JW, well were glad you only got that.. I had a prop spun up at full speed and it (luckily) flew off away from me and stuck 2cm deep in my oak entertainment center.. Lesson Learned..

Hu-ah Max..

I've since had the prop fly off twice, but with the plane across the room, and I still cannot mount it properly. It broke on the third time so now i"m trying something different, but even a smallish electric motor can really put out some force.

I got hit by a propellor flying off. Hit me at the base of my thumb. Got a pretty good scar there now.:D

I can also add the warning to anyone hand launching a pusher flying wing, be very carefull.

The scars across the back of my hand have faded, but now she gets one hell of a push with the motor off and I just hope to get the power on before she hits the ground.

Once bitten .......

yes..once bitten. We (I) get complacent with these things. I have scars on my left hand from when I stuck it in a OS 60.....only 18 stitches - but I still have my fingers.

Wow. I did all my learning on OKCubs and other less-energetic engines. When I moved over to diesels, then I had to relearn some of it...

Props cut flesh just as easily and effectively as air!

My eye protection lesson does not involve a prop ...

While building a homemade brushless motor, I decided to spin it up to evenly distribute CA glue around the magnets. A drop of CA flew off the rotor and into my eye, where it instantly cured -- stuck to my eyeball.

Luckily, the CA landed on the white part of my eye, not on the optical surface. I soon learned that CA is water-soluble, and sure enough, it dissolved on its own after a few days with no permanent harm done.

This happened despite the fact that I had a pair of safety glasses sitting on the bench. I've been much more strict about eye protection since this incident.

I also had an OK Cub 0.64 with the tank made as part of the engine. It was a very mild mannered engine that lasted forever. Ahhh the old days !!
