OK guys, I got hit with a master airscrew 6X4 prop today at about 1/4 throttle. It was my own fault for not paying attention and thinking of somthing else. I was breaking in my new engine (AP hornet .09) on my schoolyard scale space walker and I was attempting to check the temp on the engine with my temp gun and then.....WHACK!!!! Right into the tip of my right thumb, all the way down to the bone!!! No lost skin, just a semi deep cut strait into the tip of my thumb and it didn't even stop the engine. Obviously I had a few choice words, stopped the engine and went inside to acces the damage to my thumb. No hospital trips but it did hurt pretty bad. Needless to say I was back out there about an hour and a half later to find out I left all my electrics on and now have semi dead batteries.

Theres a moral to this story and the moral is........don't stick yer hand in the way of a fast spinning prop!!!

BTW.... I never did get that temperature I was looking for.


Joe

There's another moral... Any time that engine is running, make that prop your #1 concern! (Hot Muffler and Exhaust #2)

And Joe, Thanks for not posting pictures [:'(]

Master Airscrew props are SHARP! I use wood for the safety factor, they break instead of cutting, at least in my considerable experience with props/fingers/knuckles! I cut two fingers to the bone starting a .61 Super Tiger once. (Yes I learned my lesson.) The tips of APC props can be a bit sharp too. Always sand off the flash before you balance Master Airscrew props. Yes, I still use them on the "Company Trainer", 'cause they are less expensive!

I kidda no how it feels. i used to have an APC prop, VERY, VERY sharp, and i got one huge cut across my palm while tighting it. i still have the scab! and it hurt, like a papercut
get flying and you will forget about it!

We had a fellow at our field last week get cut with a wooden prop mounted on a OS 160 Took forty stitches to close it another dumb accident. So wooden props will bite ya to.

Better to learn that lesson on an .09 instead of a G62.
A safety lesson before it's too late -- NEVER remove the glow starter from the front. Take the time to walk around and remove from behind the wing. Not following my warnings, two of my students got their jacket sleeves caught in the prop by reaching over the prop. Next time it might an artery in the wrist or a finger.

Yeah you guys are prolly right. It just might be alot worse net time. But with ALOT more awareness on my mind when I am anywhere near the prop, Hopefully there won't be a next time.

Oh. and MinnFlyer, I kinda wish there were pictures so it will remind me to be more cautious around a spinning propeller!!!

Later!!!

Joe

See, those Temp Guns are useless

a G62 is quite a bit safer in one aspect, no glow to reach over! I think probably the majority of prop accidents are caused by this little thing, making gas a little safer in one regard.

anyway, I've managed to cut myself on a prop before it was even on an airplane! taking a large APC out of the package, I slide it up through the top, right past my hand. It looked and felt like a very large, deep papercut, hurt like @#)(*@!!!

One second of lack of focus cost me 19 stitches. It is difficult, but stay focused around a running engine. And if that is hard, imagine that it is a table saw blade spinning on the front. Not many of us would want to stick our hands near something like that, but the results can be the same with a prop. I saw a guy hand a radio over the prop to another at the back of the plane yesterday. I just cringed waiting for him to get hit somewhere between hand and elbow. Luckily it didn't happen, but he never even thought about what he was doing. focus, focus, focus

consider yourself lucky! I have seen far worse, including my own injury....[:@]

kokamo... you want pics? go do it again with a cammera in the other hand!
i havent had a prop accident YET and i hope i will never have to know how it feels

HA HA HA!!!!! Thats funny.......If I did have anything in my other hand, it would prolly end up huruling through the air like my plane is SUPPOSED to be!!!!! There's nothing like throwing or kicking nearby random objects just to get frustration out. [:@]

I'm sure some of you know where I am coming from.

This is starting to be humerous now.......I kinda get a kick out of it, although this in the end will teach me a very valuable lesson.

Joe

YUP!

I messed up on #1 and #2. I had just built a Kaos 40, the first time I started it I didn't have the throttle linkage quite right. I usaully set it up so the engine will idle with the throttle trim set at half or above, and I just move the trim all the way down to kill the engine. Well, with the trim at the lowest setting, the plane just idled. So, to kill the engine, I just put my finger over the carb. I was being very careful of the prop, but my hand happened to touch the top of the head. So, of course, I jerked my hand and stuck the tip of my finger right in the prop. Luckily, the engine had almost died by this time, but it still hurt. I did learn my lesson, the next time I just pinched the fuel line until the engine quit. This does lead to a question, what is the best way to shut off a glow engine?

My radio has a feature called Throttle Cut, which is accessed by pushing a button on the radio. You set it up so that when you push the button, the carb closes completely. That way you don't have to mess with throttle trim.

You can either pinch the fuel line that is going to the carburetor, or with a rag (or something to keep you from getting burned) you can plug the exhaust on the muffler. Always be careful to stay away from the prop.

I saw a mates finger after it getting "chopped" into by an Sc 120 F/S, i think, judging by the size and shape of the cut, the bone stopped it.[sm=surprised.gif]

After a hospital visit, its now on the mend.



ow[X(]

1. Throw a rag into the prop. (not recommended for wood props)
2. Pinch the fuel line to the carb, from BEHIND the prop. (not the best way)
3. The BEST way is to set up the radio, before you ever get the plane to test flying stage, so the carb will close COMPLETELY when the throttle/throttle trim levers are all the way back.

An OS .25 FX bit me good one day. No stitiches were requierd but it bled like a stuck pig. I had the glo starter in my pocket but forgot and left the chicken stick in the pits. The engine died while taxiing so I figured I'd just flip it over by hand. I didn't even feel it hit. My brother noticed it before I did and pointed it out. I looked down and blood was dripping from my finger. I was pretty lucky I guess. From then on I use a starter or chicken stick.

When I was 14, I had one of those airboat things with an OS15 in it. A mate and I were running in the motor on the bench, I was sitting in front of the prop holding on to the tiny fuel tank beind the engine with my left hand, as my mate went to squirt more fuel into the tank from a large syringe, some spilt on my fingers. I already had some small cuts from starting the motor so the spilt fuel stung, so I pulled my hand away, straight through the prop. Holding my left hand against my chest in even more pain, I reached over with my right hand to plug the exhaust to shut it down and burnt my right hand on the exhaust. Result = 5 stitches to my left middle finger and a sizeable burn to my right hand. I employed a chicken stick from that day on. Now getting back into glow 16 yrs later, Ive invested in an electric starter.

21 yrs of rc and I still have all my fingers KNOCK ON WOOD and I plan on keeping them.

See attachment.

This is the result of being aggravated with a motor that won't transition, and getting in a hurry. [sm=confused.gif]

This happened last Wed 4/21/2004...... It was a GMS .47 spinning a plastic 11x7 master airscrew at full throttle.

The prop broke, and the stupid engine that I can't get to run .... well it kept running It's a lot of fun trying to shut down a runaway engine with one hand pouring blood!

P.S.... The @#$%^ was shipped back on Thursday 4/22/2004 [:@]

Cool. We have another winner. Keep em coming.

They should sew up guys with pink thread. That would do more to stop us from getting hurt than anything else.

when i get dressings off in two weeks will post pic. warning you though 5 and half hours surgery.

Mattyd,

Hope everything turns out OK..... what's the story? What was the damage?
