Just amazing![sm=what_smile.gif]

Those stands are safe; however, the one in my picture above forces the pilot who uses the stand for the radio to stand within the dangerous zone.[sm=thumbs_down.gif]

We all become to complacent after a while. We all need to remind one another when we see a unsafe condition. I have seen guys firing up these "flying circular saws" with thier kids standing right in line with the prop. If you take the time to look around at your club and tell the members when there is a unsafe condition, YOU WILL BE A BUSY MAN!

I had a reminder of this last weekend. I was starting up my GP Cherokee with an OS 55 on it. Had the stock plastic spinner that comes with the plane on it. Luckily I was standing behind the plane running it up when I heard POW. The backplate on the spinner let go and the spinner was thrown about 20 feet out in front the plane!!

ahh, Norwegians... well what can you expect?

Hi FrankHawks
I never have used a neck strap for that same reason. Could be very dangerous. Now that I'm getting old I have more difficulty holding the transmitter because some of my fingers have deformed or curled up. I may eventually be forced to use a neck strap. I have promised myself that I will keep the neck strap in my pants pocket, with no part sticking out. Once I have the plane started and have moved it off the Engine Starting Safety Stand and placed it on the ground, I will take the strap out of my pocket, place it around my neck, pick up the transmitter, and attach the strap clip to the transmitter. Upon landing I will reverse the procedure. That is my current plan. Any comments on this?

I leave the strap attached to the transmitter and the transmitter away from the plane and prop

That is a great procedure if you must use one of those, Villa.
Since I learned from an instructor that always used a neck strap, I also used mine all the time.
After a couple of close calls, I completely discontinued that practice.
Now, I am happy just holding the Tx with my hands.

Reminds me to update my first aid kit under the passenger seat in my truck. The plane of rotation rules.

I can't stop the backfire, but this is a good example of why I do a pre-flight before every flight. Check the prop for tightness, cracks, anything unusual, which most of the time will prevent it from coming off, except a backfire, or to high of RPMs. Pre-Flights are good anyways.

In the airforce we called that the shell out line....  always stay clear of the shell out line

WOW!!!!!! Just last week end as I was getting ready to take my 50CC Pitts Python swinging a 23X8 prop to power...a newer guy walked up and stood in line with the prop.....I asked him to please move and told him if the prop were to let go it would fly off in line with the prop.....then I felt kinda silly as I have never thrown a prop....After seeing that I am glad I did...
Thanx for the reminder....Oh and by the way it was 3 years ago Thanksgiving that I rearranged my fingers on the OS 1.60 and an APC prop......prop went long wise through the bone on my social and ring finger at the tip.....and 21 stitches total to those two fingers and my pinky......So please please be careful...
good flyin to all

The problem with this reply is that it's the instructor's responsibility to see that this sort of thing does not happen in the first place. Dropping a student for making a mistake will wein the hobby down to two experts.. and I'm not one of them.

I was taught not to stand in front or to the side of a running engine. The only time I'm in front is during the start-up and run process, with any "close-in" spectators behind at all times.

I also teach the same thing to students. It's like muscle memory.. imbed those processes early on in training (like from day one, hour one, minute one, second one) and right or wrong, they stay there for a long long time. So, try to make those initial instructions worthy of the hobby and of the quality of the instruction.

I make darn sure that when I start the engine, no one is in front of the engine but me (it's awful difficult to start it from the rear). Then I move to behind the engine to do whatever I have to do to get ready to fly, all the time making sure that no one is around in front or directly on the side of that plane with the engine running.

That goes for electric, too, by the way. I'm sure they will throw a prop just as quickly as a glow or gas engine will if not treated correctly or if, asd Mike said, the prop meets it's expiration date. Just consider the RPM range of some of the electrics.. centrifugal force is an awsome power and always a potential prop thrower!!
