Safety - RC Helis are not toys > 6 Stitiches in Hand

Safety for all, please Read

I promised myself that I would pass this on to all. If this prevents one person from having the same type of thing happening to them, then I will feel better. I had an accident yesterday, in which I as a newbie; caught my hand in the fly bar paddle shaft that extends past the lock nut. Ripped the hand open in two places with 6 stitches later to close.
Have I got your attention?
I had my 30 size heli on a work mate, clamped down with out the main blades (I read some place that you should do your first tests on a new heli this way and it’s a good thing too) on as I wanted to do my first test run on the engine and mechanics. I was on my second tank of fuel with all going good, trying to set the idle. Things were progressing well and was able to control the engine rpm both up and down and back down to idle.
During the second run at about 1/2 tank of fuel, I had the heli set to idle. All of a sudden, the engine went to FULL throttle. I looked at the radio, and the stick was at the low or idle setting. I picked up the radio, and tried some inputs, but had no control. I then went to the side of the heli where the throttle linkage is, and looked at that. I noticed that the control rod was missing. (Actually the vibration set the harmonics so that it appeared to not be there. I reached down to move the throttle back to idle and engine cut off, when WHAM I was hit in the right hand just below the little finger in the fleshy part of the side of the hand. Never felt it.
I pulled my hand away, and looked, saw two GASHES, DEEP, and tried to think of how to shut this darn thing off. I figured my only choice was to pull the fuel line off. I went to grab the line, and when I went to pull, I also squeezed the line, and the engine shut off almost instantly. Went into the house, got my wife and went to the Urgent Care office. Six stitches later and here I am.

Now in hind sight:
I should NEVER have tried to reach for the throttle linkage. Just squeezed the fuel line to stop the heli first, and then solve the problem.
Up till the point of going full throttle, I was aware of the fly bar paddles, and was very careful around them. Due to the change in the operation of the heli I reacted with out thinking things through.
The paddles are black; I did not see them when they were at full throttle. I will add some white tape or something so they will be more visible when the heli is running. Thank God I did not have the main rotor blades on.
I will not panic next time, but sit back and analyze the problem and how to remedy the situation before taking action.
Going full throttle could have been caused by exhausted TX battery or some interference on my channel. Mechanically all else looked sound. Always top off the receiver battery before flight or testing.
Above all, respect this machine as it is no different then a power tool in that sense. Have respect for it and follow all safety instructions.
I am now a true believer in safety really always have been (just got dumb for a second or two); this machine is NOT a toy. Keep that in mind at all times.

Remember, think before you reach. Be aware of your surroundings, etc. etc.

Looking forward to comments. I know that I did a REAL dumb thing and I'm lucky to get away with just 6 stitches. I just hope this helps someone else out there.

Spinning up without a load is a no no, either a head loader or blades are a must . Thanks for the post

Sorry to hear about your misfortune
Where did you read this information?
Just cause its in print or on the net doesn’t make it gospel

It still baffles me as to why people think strapping there heli to a fixed object is the best way to run-in a heli??? In fact a majority of heli accident related stories are down to the fact that the heli has been strapped down in one form or another......

Glad to hear your still in one piece, and that you have walked away alive, as the consequences could have been alot worse.

Actually Ruff, I'm more intrested in the blood end of it. I do have a buddy that has been flying for a number of years. He and I will be hooking up.

Sorry to hear about your accident,

I remember doing the same when I first started , tying the heli down
thinking that it would be safer but it was actually more dangerous.
I think it has something to do not knowing how to fly and the fear of the
heli flying off the ground and losing control of it.

Live and learn, getting together with another experienced pilot is your
best bet.

Good luck and be careful man, for yourself and others,

Head Loaders

SENECA
I don't quite grasp the idea behind the head loaders or their purpose, but if that is what I need, can you tell me where to get them. I will have to place an order right away.

Thanks,

I think that strapping down a heli and running its throttle up is very very dangerous , headloaders notwithstanding.

I agree, headloaders and pegs are unnatural, the worst thing that happened to me was in my hallway, I was setting up a concept 30 and realized the tail pitch was inverted, so I reversed it. Of course being the bright young lad that I am, I reversed channel 3, well you can pretty much guess what happened next, all I can say is, thank god for nylon gears that strip so eaisily. I got a big bruise, but my hand on the rotor head was able to hold it for the 3 seconds it took for me to realize my stupidty and have the main gear strip. That in my mind is the most dangerous thing, throttleservos reversing, more so on electrics where its hard to tell which is positive or negative throttle.

To all of you that took the time to read this post

Thanks for the all the advice. I have to admit that I thought that I had respect for the heli and what it could do. I now know different. I respect this machine 100 times more than before. I can only say that I'm glad that I was not injured worse than just six stitches, could have been a finger(s) etc. or worse.
I'm glad that this happened at the start of my learning process. When something like this happens, it makes you step back and REALLY REALLY think about what you did wrong, and what you did right. I can only say that this incidnet will make me a better, safer flyer. I will ALWAYS think safety first. For instance in the future I will try to think of the possible things that can go wrong, and develope some type of a plan to minimize the risk both to any bystanders, and myself.
As I stated in the first post, if by posting this on the BB will help just one person, I will have done what I set out to do. Prevent an injury.
Thanks again for taking the time to read the posts and happy flying.

Sorry to hear about the mis-hap. But, if your heli was shaking so bad, as to make the linkage appear as if it wasn't there, you have some serious out of balance problems. I know that locking one down will create harmonics, but I don't think they should be that bad. Check your fly bar for balance and centering. Just a suggestion.....

Glad your injury was relatively minor, hope it heals soon.

A better (faster) way of killing an engine is to block the exhaust. This will shut it down like a switch. If you have an exhaust diverter installed all you have to do is pinch it for a second. If not, keep a rag in your pocket.

FYI, the reason your heli shut down so fast when you pinched the fuel line is because it was already running lean. If the mixture had been correct it would have run for a few seconds (increasing its' rpm as it leaned out btw) after you pinched the fuel line.

I'm surprised no one has suggested staying away from a helicopter that is running, especially if it is at full throttle. Reaching under to shut off the engine is very tempting, but we've just seen what can happen.

I've seen crashes where the thing just wouldn't die, and sometimes you just have to stand there and watch helplessly or avoid your own injury.

Janek?

Hey everyone,
Janek I was wondering about your reply ( That guy should be sued, maybe he would then remove that piece of really stupid advice from his book. ). Maybe you could just explain why you think that is bad advice. I have Rays book and in his example the heli is actually above your head, I'm only 5'11"( he shows his idea of a run up stand using a 6 foot ladder ), with this type of set up you would actually be reaching under the heli from below it therefore staying away from the rotor blades. It seemed like a good idea to me. I have not done it yet. So if you could please let us newbies know why you think it's bad advice. By the way when I first started looking to get in to helis many people said his book was a good source of info so I bought it. I don't mean to start any flame wars but was just wondering. Thanks

Strapping the heli down at any height is a dangerous situation performing engine test runs. Moreover, beginners are likely to attempt this type of test stand and will definitely increase the risk of an accident.

Do it safe and perform engine test runs by flying the heli at the flying field 10ft - 20ft away from you and not inches from you.
