But just as dangerous too. The guy who started this thread was ''bitten'' by an electric. Permanent hand damage.
P.S. How is medical school? I was originally pre-med but changed my mind. 29 now and would need to take a couple classes before applying to med school.

Been flying for 19 years on an off..Im 27 an unfortunatly have given up on nitro/gas planes. As a 4th year medical student i really cant afford gamble with my hands. There for I have switched over to electrics an helis. Still just as fun

RE: Prop Bitten
Though this is a heli rotor bite, I suppose it belongs here to remind people to be careful with helis.

RE: Prop Bitten
Just getting into helis from planes myself, those things make me nervous. When bigger ones spool up, it is easy to see how they could cause an injury that would make that video look like a paper cut.

Agreed. Starting a plane this way is foolish at best. You're basically putting your entire body at risk.
I set my 50cc props so TDC is about 12 o'clock. That way your hand is out of the way with time to spare.
The only time I was ever ''bitten'' was a lapse in judgment on my part.

I wouldn't say it's safer to start a plane while stradling it from behind. Possibly if your knees are on the ground. But standing and leaning over you are more likely to lose your balance, I would think. And the possibility of tripping over the plane after it starts also.

I have seen stabs break while a second person is stradling the tail, as the operator is in front doing a full run up, no thanks.
Witnessed props and spinners and locknuts come apart from others over the years, being in front is not the best place to be.

RE: Prop Bitten
These pictures and videos sure make my little incident ( half a dozen slices on the ends of the right index and thumb ) seem very minor. The culprit was a o.s. 10 with a "a precision cut" prop that i was bench testing, though as it turned out the bench was not very good and wobbled to the side at a very inconvenient time. It was still kind of bad but nowhere near as bad as some on this thread as I do play piano at a fairly high level. Also from this thread I learned that electric is not safer then glow engines. Hope all the people who were bitten here get better fast.

RE: Prop Bitten
well, i supposed i was pretty lucky compared to alot of you guys, but heres my story any way. a couple moons back, when i was just getting my thumbs into shape, i bought my first glow powered airplane. mind you, i only had less than a summer worth of self taught experience. i basicly had none. but i had to have a " gas plane". so i showed up at the local flying field, that i now belong to, and asked around. In about four minutes i had bought a SIG Astro Hog with a K&B 61. I couldnt wait to get home and start it up. not like i can fly it at home, but you remember how it was. Any way, I fired it up, reved it a few times, and came to the conclusion that it needed to be tuned. Mind you, it was probably running like a clock, i had no clue. So i reached up there , about an inch behind that 12 x6 prop spinning around 12000, the whole time straddeling the tail to hold the thing, lost my balance, and the closest hand to the ground, was right behind the prop. WHACK. Well, that old K&B never quit. The plane lurched foward, and my first reaction, not knowing what i was doing, was to shut off the reciever. Now i cant throttle it down, so i picked up on the tail and let the prop hit the ground, which wasnt very smart either. needless to say, i took the top of my pinkey knuckle clean off, bone and all, along with a grteat deal of flesh. 6 months of physical therapy, and alot of time lolst from work. I learned alot that day. Pffff, i sure hope so. the biggest thing, i shouldnt be messin with something i know nothing about. after a whole season off, and alot of thinking, i decided, i will still get into rc airplanes, but i will join a club, and actually LEARN how to fly. The best descision i ever made when it comes to this hobby. I now fly 1/4 and 1/3 scale planes, with a lot more potential for injury or even death. Thankfully i can say that i never since had even the smallest incident. Ive learned sooo much from the guys at the club, and consider myself a good, safe pilot. I hope even one person reads this and decides not to go out and but that big ol dengerous plane or helli, untill you actually know how to fly it. In the end, I was lucky, but it doesnt mean it cant happen again. Steve.

wow, that was a big wake up call, ouch. Glad you are doing fine all around now. Enjoy.

Call it luck or whatever, but one thing I can state is that I am very cautious around anything spinning with power to do damage. I don't care about those that laugh at taking safety precautions or the way I start my planes. They can laugh on as I still have my fingers.
I hope others at least take some time to consider the danger and use a little extra caution. There may be a young person watching you and you may be saving him from getting hurt one day when he decides to take up the hobby. Happy and safe flying!

RE: Prop Bitten
I have a healthy FEAR of a spinning prop so I have started installing remote glow plug connections on all my aircraft. IN a J3 Cub I have it inside and I open the side window to connect it. If I have an opening canopy it goes in there. I try to place it at or behind the leading edge of the airplane. Most my engines are such if I keep my paws off the needle I don't need to readjust them so I have no reason to get too close. I start the airplane from the front and I prefer having someone holding it even when using a tail trap. Now don't go thinking I'm any smarter than anyone else, I still have scars on my fingers from a Cox .049 from when I was a kid. My lessons were learned the hard way!

Never knew props can be so nasty!

A prop can be unforgiving but there are a lot of sports that can cause serious injury and even death. The trick is to make safety precautions a habit and never deviate from performing them. Accidents occur when we get sloppy! Every propeller strike I got from an .049 when I was a kid was my own fault period. Remember the old saying: There are old pilots and there bold pilots, but there are no old bold pilots!

RE: Prop Bitten
I got an email today from Aero Perfect they had a Behind the prop Starter set up they had discontinued but they are considering offering a kit including the plans and the hardware you build yourself. You might take a look at it on their website www.AeroPerfect.com . I think it would be a great idea to use particularly when and extra pair of hands aren't available at the flying field. I have already contacted them an requested they let me know when it's available. If it looks good to you and you think you might like one drop them a line.

RE: Prop Bitten
I thought I would add to this thread,
I was running my 3W-157 engine up at a festival for some spectators that wanted to hear the engine run. I had everyone standing back behind the propeller arc except for myself as it was pretty crowded. I knew better but I thought well it will be fine. As soon as I went to full throttle the prop bolts broke and the prop immediately departed the engine and hit me in the arm shearing 6" off the tip of a 32" prop on my arm and the prop flew another 75yds before landing.
I was very lucky that the prop did not hurt anyone else. That was my biggest concern as I looked down at the gash in my arm. The impact on my arm was so strong I thought for sure my arm was broke. After a quick trip to the E/R I found that no bones were broken and the laceration was superficial as it did not go thru all the layers of the skin. I was extremely lucky.
You will never see me standing anywhere near the front of a prop as it is being run up and I will never start an engine for a crowd of spectators to see. Just not worth the risk.
Later!!

I was lucky when I learned to respect the prop back when I was young and stupid and was using an old .049 Baby Bee. The most danagerous thing you can do is get too comfortable with a spinning prop, and it is so easy to do. I have been lucky the few times I have slipped but....

RE: Prop Bitten
It was a wooden prop,
I shy away from carbon props and glass filled nylon props for this reason. They will all hurt you but wood will at least break and splinter easier reducing the impact force. I was dumb enough to stick my hand right thru a 11" Master Airscrew prop years ago reaching for the high speed needle. Almost lost a finger to that mistake.
Here is a pic of the prop that tried to eat me alive.

The original post at the beginning reminds me of my stupid mistake...years ago, I had a Dumas Big Swamp Buggy that I was about to "run-in" the nitro engine on. I got the engine started and without thinking at all, I'd reached for the needle to adjust idle but instead of reaching around the back of the engine to mess with the idle needle, I stuck my fingers right into the prop and WHAMMO, hard lesson learned. Same thing, tore up tendons and veins, loads of physical therapy and worse of all, lost wages. Hobbies like this along with many others, you really need to pay attention.
