RE: Be extremely careful!!!!!
 

And I thought I was all alone up here in the tundra country. I find daybow from Sioux Falls where we lived when the population was 40,000. kickflipkid687 from Saint Cloud where I live now 100 miles west and Grafton ND where I have visited. I live in Morris, Mn. and started building in 1945 when testers was the big glue. Didnt realize I was getting high on that stuff. Stuck to your fingers some what and youd suck it off. Did'nt know any better I guess. Will try that ca for minor wounds. Hand propping was the only way to go back then and I have many scars.[8D]

RE: Be extremely careful!!!!!
 

CA has been used for internal stitches (i.e. during surgeries) as well as surface wounds. The military experiemented with it for use with blisters, decapping the blister and "reskinning" it with a drop of CA.

Some data indicates that it was the medical community that pushed CA's development, though I've never found any information to substantiate that claim.

RE: Be extremely careful!!!!!
 

Was reading the earlier posts with interest - and just so happens that I feed my RC habit with my dayjob as a physician.

Actually - cyanoacrylate "wound glue" has been in use in emergency departments for years. We mainly use it in the pediatric population, but I am not certain why its use has not been expanded more. We have lots of options for closing a laceration if we can get a look at it quickly, and it is only closed after a thorough irrigation - frequently washing with a half liter or more of sterile saline under pressure (after any planned anesthesia with lidocaine, of course). We use special super-glue with a pretty blue coloring in it (I think that is the only real difference, except that I am sure it costs $50 or more).

So the answer is - yes, super glue is used by physicians for lacerations and works well for this application with a little training in its proper use and after evaluating the wound and ensuring it is as clean as possible.

But the warning that goes with it is - No, this is not recommended for routine home use because of all the other hundreds of things that can go wrong with a wound like that that. We can make the experience much less painful then (with local anesthetic) and later (with a pain medication prescription for home). If indicated, we can start antibiotics, a nd most importantly, we can catch problems early before they are anything serious. We suffer through weeks and years in dark classrooms fighting sleep listening to lectures and studying minor trauma and bacteria and pharmacology and histology, etc.. followed by examinations to make sure we remembered everything, and lastly years of residency to make sure we know how to close things correctly - and just as importantly know when NOT to close them.

I know most prop cuts are "nothing" - but is it really worth a lifetime of disability resulting from the inability to feel a finger with a damaged nerve? Or worth the risk of the loss of a finger (or multiple fingers, or a hand or an arm if it spreads) from infection? Its a pain in the rear but when accidents happen, let a local physician apply the super glue and you will get a free bonus lollipop and perhaps a SpongeBob band-aid. Bring your electric helicopter with you and fly it in the lobby while waiting.

They do use it in emergency rooms. The disolve the stuff using solvents that are less harmful than CA but the polymer is the same stuff.

RE: Be extremely careful!!!!!
 

Thanks for the data. I am (was) an ER nurse and saw the use of the stuff under those circumstances. Also witness several surgeries where it was used while in school (special circumstances, as you might imagine). My wife is an oncology nurse (current) and my brother is also a GP.

It helps keep me a bit more current than the general public (G).

RE: Be extremely careful!!!!!
 

In this entire thread, I find one thing missing.

A warning that these aircraft are dangerous, and should be treated as such.

I see the same thing at the flying fields, a total lack of respect for the danger inherent in these TOYS. And Electric is somewhat more dangerous. With a Glow Engine once it hits you hard enough, it most likely will stop running. With Electric, after the motor gets released, it comes back and gets you again.

I've had my share of Prop hacks over the years, but am more cautious now because of them. And its been awhile since I've turned on a plane without first checking that the throttle was in the lowest position. I also make sure to stay in a position where if the plane should come alive, it can't get me.

Be it CA, Epoxy, or stitches in Emergency, they are all avoidable by developing some respect for the dangers involved in this hobby.

Technology has given us very dependable equipment, but as always, it's the loose nut behind the wheel (Transmitter) that causes the major problems.

RE: Be extremely careful!!!!!
 

I've been hit in the fingers by props on 60 engines, I've been cut by props on engines from 020 to 45, but the messiest and bloodiest came from an 8-4 wood prop on an old Parma Cyclone II on a Goldberg Mirage. Fueled enigines tend to want to stop when the prop hits something. Torque goes to 0. Electric motors, on the other hand, slow down, draw more current, and try to overcome the obstacle. Torque climbs.

I knew a guy who cut the tendons real bad on 2 fingers on his right hand. He was a barber and what 2 fingers do you think were cut? Yup, the 2 he held his scissors with. He's not a barber anymore.....

RE: Be extremely careful!!!!!
 

Actually guys super glue is very common for minor cuts that need stitches in the E.R. and other places in the hospital.I've worked in ICU's and ER's for ten years. Some surgeons use them to close incisions in surgery...big ones!! Of course it has a nice medical name(Derma-bond) and is probably manufactured to some degree of sterility but it is essentially the same stuff.I also know from experience that regular superglue works awesome!!

RE: Be extremely careful!!!!!
 

Props can be very dangerous. In 1986 my left index finger was struck by a prop on an O.S. Max 30 at W.O.T while adjusting the needle valve. I received 21 stitches and had my hand in a cast for 5 weeks! The is a big difference between a slimmer and an electric motor. When a slimmer hits something it slows the engine, however, when an electric motor hits something it pulls more amps as it pulls harder, trying to maintain its rotation speed. And thous GWS props are very sharp. A word of caution just because it is electric does not mean it can't hurt you.

RE: Be extremely careful!!!!!
 

I couldn't agree more the ALTACOM. In the couple decades I've been in the hobby I have seen a slow but progressive lag of respect for both the models and fellow modelers. It seems that as prices fall and less work and skill is needed to build a model the more scary it gets from a spectators view. IMO.
Now little things happen often by accident sure, but its the overall attitude that keeps me from flight fields more and more.

Now I use a connector on the motor all the time, BTW

Sorry about the finger, I hate it when that happened;)

RE: Be extremely careful!!!!!
 

Just this last month I was at a local Flying field, and saw a perfect example of where we are in the Safety aspects of the hobby.

There were 2 incidents actually that got my attention..

First to the 3D flyer. He obviously was a good pilot or he couldnt have done the stunts he did. It was about a 60 sized 3D plane, and he was doing great at altitude. Then he swooped in over the runway, went into a hover about 15-20 ft out in front of my flight station and proceeded to lower the plane until the rudder almost touched the deck. At the field we have no protection on the flight stations, and had he lost it, I might have been badly damaged. As it was, I just backed out of the flight station and moved almost into the pits until he pulled out and went back up.

Second incident same day. A guy with one of the little Meat Tray Electrics was flying low and slow and just tooling at about 3-4 ft above the runway, and also within just a few feet of the unprotected flight stations. Once again I backed out of the station and moved back toward the pits

It's getting to where I only fly at our local soaring club where there are nothing but Electrics and Gliders, and the guys are very safety concious. The Safety officer has setup good riules, and is more than willing to let someone know when they are in violation.

you are a much better man than I. I would have been going ballistic on him. It seems people have no respect for the inherant danger or each other any more. I only fly park flyer electrics now, so I do not belong to a club. However, at the last club I belonged to we had a couple of hotdogs who hated me because I would get nasty when they flew in a dangerous manner.

I make no excusses for yelling at them for being idiots. I have a messed up finger because it was nipped by an OS 30. I would hate to see what a nitro powered 60 or 90 would do if it hit you in the face.

Sometimes there is no room for nice.

RE: Be extremely careful!!!!!
 

I flew most of the month of July last year at a field where there were some real hot dog flyers. Most planes they fly are Fueled, and in the range of 40-60 with a few of the big 1/4 Scale models. I flew there for most of the month of July last year, and never once felt uncomfortable.

This was at the Seattle RAMS field in Sumner Wa. I was flying as an out of town guest of my Son-inLaw.

They have a strict rule about safety. No more than 4 planes in the air at any given time, and usually there were only 2. You MUST fly standing in a 3 ft high safety cage, and if you arent in the cage, one of the members will come out and guide you into the cage. Engines cannot be reved up in the pits unless someone is holding it. They use the buddy system and help each other in every manner to fly for fun, and fly safely.

A new flyer is not allowed to fly without an experienced pilot in the cage with him. And they recognize a new flyer immediately and one of the members will immediately latch onto him and assist him to learn right.

I get the impression that they all are the safety officers for the club, and it works.

Granted most of the guys that are there the majority of the time are older, 50's and up to 80. So they have been there and done that, and dont want to get hurt, or even worse hurt anyone else.

If the AMA were to ever give awards for a club that was safety oriented, it should go to the Seattle RAMS

Sounds like a great place to fly!

Hi David,
I too, suffer fools, morons and social maladoits VERY poorly. As a competitive shooter, airplane junkie (motorcycle, sportscar and sailboat racer) SAFETY has long been one of my main issues.

However, I've found that, at least in the initial appoach, a GENTLE demeanor accomplishes more than the lite fuze approach. IF, the situation then develops in such manner, the heat can be ratcheted up as necessary.

As an example, a couple of years ago I was at a local (public) shooting range testing match (rifle) ammo. The man next to me had his young son and was attemtping to teach basic marksmanship. He (as is often the case with family) ran into some problems getting some concepts across to the kid and asked if I could help. I proceded to work the the man and his son for some time.

During a Cease Fire, one of the volunteer "Safety Officers" came over and MASSIVELY got in my face. I was only a couple of years younger, if at all, than the Range Nazi. The PROBLEM was that that man went off the edge without having his FACTs straight. He told me he could throw me off the range for "Drawing a pistol" - only problem was that neither I, the man or his son were shooting pistols, let alone having them on the range.

The fact that the man approached me at full throttle was simply the wrong thing to do. I have a VERY slow fuse, but once ignited, that sucker is HARD to put out.

I don't know of the SO was having a problem that day, medications, perception or what, but SOMETHING was wrong both with what he THOUGHT he saw and with his approach.

Needless to say, he pushed, and I pushed (figuratively) back harder. I also filed a formal complaint and (ultimately) had the man removed.

IF he had come to talk to me, to find out what was going on (if anything)... IF he had been civil, then MY reaction would have been VERY different.

I do agree that morons WILL act as morons, and it's likely that the gentle approach may be wasted.

BUT.....

The cost is so small, why not start out softy and adjust as needed?

You make some very good points. I am usually polite the first time but the second or third time nice is out the window. My four teenage kids fly and when it come to their safety I am like a cornered dog. Life is short enough.

No argument there! The sad fact is that we seem to see an across the board degeneration of both courtesy AND intelligence in our "public life."

I guess I was a late starter, our kids are 7 and 12, but I too, have the "momma bear" syndrome when something endangers them.

OTOH, if either of them behaved in public as I see the majority of kids doing, NEITHER one of them would survive to drivers license age!

RE: Be extremely careful!!!!!
 

I fly at a club here in Orlando- I have seen a "40" size plane fly right into the clubhouse. The plane flew right above a bystander not watching the planes, misssed his head by atleast 1 ft.

Safety is a must! Watch the planes flying even, be aware. I was chased by a 1/4 scale starting up and the pilot had it at full throttle upon start up.

<call me lefty, almost lost 3 fingers in a start up with a ".46" 2 stroke- I hate to imagine how much damage an electric can cause when the prop does not stop.


Take care

RE: Be extremely careful!!!!!
 

Learning by making your own mistakes is a very expensive and potentially deadly method of learning. A lot of the older fellows I met in this sport often got touchy on the subject of safety. They don't want the younger members to have the same scars and hospital stays they had because they thought they didn't need to pay attention to safety.
One club member, who just passed away a couple years ago had lost a portion of an index finger including all the fingernail because he let attention drift. He also spent several days in a hospital by slipping while standing up and grabbing the transmitter and trying to hold a 60 powered plane all at the same time. Hand slipped on the plane, he lost control of the transmitter, knocked the stick to full throttle, and had the plane crawl up his leg. Gashed the Femoral Artery. If he had been flying by himself, he would have bled to death in a few minutes. Luckily there were several First Aid trained members who were able to control the bleeding and get him to a hospital that was about 10 minutes away from our old field. Another member ran up to the front of an idling 6.5 K&B to make a last-minute needle valve adjustment. His finger stopped the engine and broke the MA prop, but he needed about 12 stitches on two fingers and 8 months of physical therapy so he could get back to his regular job-a professional industrial model builder.
Maybe the approach of somebody coming up to you this way might seem abusive or insulting, but check out the reason and listen to the messsage. He might have learned what he's trying to tell you the hard way. And if you think it can't happen to you, you're 100% wrong.
And if you're one of the people jumping on another flier trying to stop something bad from happening, stop and think before going after the alleged violator with an aggressive approach. You're at the very least going to be ignored, you might start an arguement with hard feelings spreading through the club, and some people approached like this might even start repeating the offense just to spite the intruding busy-body.
The thing is, most people will respond to courtesy with courtesy, respect with respect.
And don't forget, the trailing edges of most manufacturers' props are sharp enough to give a serious cut without even turning over.

RE: Be extremely careful!!!!!
 

And as an afterthought, if you go after somebody you feel is doing something wrong, jumping on him could distract a flyer long enough to loose control of the plane and cause a bad accident that might be avoidable with a more rational approach, in which case you would either be sharing blame or possibly even be causing the accident.
