RE: Prop Safety
I agree, I happen to like APC props and I would hate to have them made unavailabe to me just because some lawyer convinced a jury that they are too dangerous for us. What next? Glow engines?

I am sorry NS but there is a known risk when working with spinning props that a law suit for an injury would be as rediculous as that woman who burned herself on McD's coffee and sued. As I did and many others people in this country need to take responsability for their own stupid actions and quit trying to lay blame on anyone but themselves.

That happened here, then the show Seinfeld made a spoof of it. She did win some 400k lawsuit but later on it was reduced "considerably"

RE: Prop Safety
i just have to say the woman in McD was jsut stupid, next time they should give her a cold coffee or something... maybe i should sue the makers of my teasmade?
anyway, the advice for painting the tips sound good, even better if you are the prowd owner of scale cessna or a warbird (such as a corsair or mustang) in which case the tips would look more realistic. cut out a bit of hose pipe and cut it open so you can get your finger inside, that may help save a few cuts

RE: Prop Safety
Here ya go. This is what one prop seller prints.
Do not operate any propeller until you have thoroughly read and understood the following instructions and warnings!
A rotating propeller has the potential to be very dangerous and can cause personal injury. It is the responsibility of the user to be aware of this fact and to operate it with extreme care, common sense, and good practices. Inspect the prop before each use for any signs of damage or irregularity. Remove and replace any damaged or irregular prop. Do not attempt to repair it. Be sure that it is balanced and mounted properly. Check the prop bolts often for proper security. Do not allow a spinner to rub against the prop. Do not hand start your engine. Always remain clear of the rotating prop blades. Never reach toward a spinning prop or allow anything or anyone to come near it while in operation. Keep people behind the plane of the prop. Do not run the engine at high RPM in the proximity of personnel or property. Always operate over a firm surface. Never attempt to stop the engine by throwing any object into the propeller.
Here's your sign.

Yea, I read that statement too. It still doesn't make the arc of the prop any more visible, and sometimes the operator has to get close to it. I will concede that most modelers have enough common sense to respect it, and that they also understand the risk. To each his own I guess, and there are alternatives available to me, so I don't have to purchase the brand fortunately. Call me what you will, but I don't have to like that brand even if everybody else says I'm supposed to. Also, I really don't have to spend my money on this hobby if I no longer wish to be involved with it. I can just as easily, and probably more cheaply, rent a Cessna 150 and an instructor. Which is exactly what I plan to do when APC completely takes over the market (but not until then, as I can still purchase Master Airscrew, Zinger, and Top Flite wooden). I bet I can derive at least as much, if not more satisfaction out of full-scale than R/C.

RE: Prop Safety
Hopefully, this thread will stay on topic, prop safety, instead of straying any more into yet another APC vs Master Airscrew, etc discussion. Each camp has their reasons for choosing one over the other, and many of us use both. While the tips of APC props certainly are sharper than MAS, either of them will do lots of damage if they contact a body part.
The risk of injury from striking the prop is real for any prop. Painting the tips of props to the color of one's choice is certainly a good idea and anyone who is concerned about the visibility of the prop arc could do this. Personally, I just don't do anything that would expose one of my body parts to the prop arc. I really hope that some future law suit doesn't result in all props being shipped with day glow orange tips!

RE: Prop Safety
The best answer is be patient and have a set routine. Be extremely careful and don't let anyone around your table to distract you. Always have the plane in a restraint and before you apply the electric starter be sure the plane is pulled tight up against it. This way it can't move. Never have the radio directly in front of you as you could hit the throttle lever by accident. I used to reach from the rear of the plane to remove my glow igniter. But since seeing a bad incident I now use remote glow igniter's on all my planes. They are mounted next to the radio switch. I also put rear mounted needle valves on my engines so I am farther back from the prop. I also think the leather glove thing might be great for you until you get a routine. Good luck and be SAFE!!!

RE: Prop Safety
A lot of great suggestions. Thank you everyone. I went ahead and painted my props with white tips. When I was breaking-in my engine (O.S. 40 LA) to my Avistar, I could clearly see the tips. Not that this will be any reason to be careless, but the white tips certainly reminded me that there's something there.

RE: Prop Safety
I have seen several serious accidents from people sticking their hands or fingers into the arc of a prop. A couple of these required surgery, most required stitches. Always exagerate your movements around a prop. If you reach around a prop, If it's a 10" prop reach 20" around it, and remember to do the same thing coming back. Never try flipping the prop by hand. Always scrape the edges of a new prop to take off the sharp flashing on the edges. Again, never flip a prop by hand. Electric starters and 12V batteries are cheap, fingers aren't.

RE: Prop Safety
get yourself a cheap Starter off the fleabay, get a small 12v lead acid battery used in model boats and such and strap it to your belt, there you have a portable starting system! ^_^
just a thought... ya'no..

RE: Prop Safety
Here's something to think about, a 12 inch prop turning 12000 rpm has a tip speed of 628 ft per second. That's about half the velocity of a .22 long rifle bullet. It's about the same velocity generated by a 200 grain .38 special bullet shot out of a snub nose revolver. Do you really think that a rounded leading edge would make any difference should you be unlucky enough to get your finger in the prop's way? Bullets have round leading edges after all.
