I used this handle and others like it at The Nats and many other contests.  I have NEVER had an issue until this Wednesday. 
In order to utilize existing models and control lines, I shop-fabricated handle extensions using .047" music wire, copper wrapping, solder, and heat shrink tubing.  These handles have survived the burtal 75-100 pound pull tests in carrier.
On Wednesday, the carrier Event Director, who was also a serious contender of the Ely Awards (all Rule Book events combined), charged that I had more than two clips per line.  When I showed him that that extentions are not clips, he wouldn't give.  He went into a two-day vendetta trying to dredge-up a case or somebody to support him, with no success.
The role of an official is to prevent cheating to gain advantage and to exclude unsafe equipment and not use power to ward off competition.

I originally got the idea of handle extensions while flying Perky speed at the AMA Nats.  My lines came up a little short and the EVENT DIRECTOR suggested that I should get some wire and exend the handle.  As long as it's not a clip and it exceeds the strength limits, it's legal.

Did he file a protest?   I have done extensions, but the conection was inside the wing where you could not see it.   Did you get to fly with the connection?   I too have had people doing oull tests complain about some of my connections especially since I have started swadging my tubing.   Big difference between sadging and crimping.  I do not like crimping as I have had a wire or two cut.

I, Paul Smith am the owner of the handle.

Pete Mazur, who was Event Director and also the prime competitor in all Rule Book events, initially disallowed my handle, but "generously" conceded to "let" me use it this time only.  There was no need for a protest.  Two days of intense digging did not produce any grounds for Pete's complaint.  I plan to continue to use these handles, taking the failed attempt to disallow them as proof of their legality.

The role of the competitor is to be sure to have legal length lines ahead of time and avoid controversy.

YES.  VERY TRUE.

I did exactly that.  Upon measurement at home I found that some leadouts and handles came up short, so I shop-modified a handle to GET LEGAL. The extentions are made of .047" solid music wire which massively exceeds all safety standards. My extenstions are strongest part of the system.

Nobody has ever complained, except one Event Director who was also a serious competitor in the event he was directing.  Despite exhaustive efforts by him, nobody backed his position.

Why not just use longer handle leads with the normal clips rather than the extentions?Seems pretty easy to change the handle wire rather than have anyone have an excuse to question it. Just my thoughts.

If I were the CD I would have probably declared them illegal without seeing how they were made but would have allowed them if all of the other competitors agreed.  What is an extension anyway other than a very long connector unless it was directly soldered to the handle wire.  I read the carrier rules, and they don't appear to override the general as do the stunt in part. The problem as I see it is the lack of clarity in our rules. For example a connector is "a thing which links two or more things together".  An extension requires that the two parts be physically linked.  That would make your "extension" by definition a connector.

I am with Bill.  It is your responsibility to make sure your plane is legal before you enter.  The place to debate a rule is here, not at a contest.

Paul, why couldn't you just put a new longer cable on the handle? No question that would be OK. The legality of what you did may still be in question, but regardless, most people would agree it's not best practice.

Some people get too hung up on 'rules'! They must take them to the 'N th' degree and where there is scope for interpretation they will argue their interpretation is the right one! If the rule on line length is, 'X' from fuse c/line to hold position of handle, how that is achieved is immaterial providing it meets / exceeds the ACTUAL safety test! People often make up for damaged lines with re-crimped / re-made ends and use over length connectors to re-establish overall length but no one worries about that! Life is too short particularly at (for a lot of us) our time of life to let pettiness cloud judgements and enjoyment of just doing stuff!

In this particular situation, I'd say having a 'rule enforcer' also being a competitor is a direct conflict of interest and would inevitably lead to some sort of confrontation or bias call. To be impartial, you can't have ANY 'skin in the game' !

Isn't there a 6" rule for the handle?  I assume that the cables are considered part of the handle.  The only real solution is to make up a proper set of lines.

I think the 2 clips per line rule was made long ago when the slide lock clips would get sideways and yank apart if there were too many stacked together. The days before heat shrink tubing.

Your extention construction is sound with the heat shrink tubing keeping everything straight and proven by pull tests.  .047" wire is massive, might have used .032". I would be more worried about the cross bar bending and pulling out of the wood. That would probably hold until 250-300 Lbs. (I have tested many things to destruction).

The 6" rule applies to the RIGID  part of the handle which could be used for whipping.  Beyond the "point of flexibilty" there is NO LIMIT on the amount of flex.

When the predatory ED who was out to get me shopped around for supporters, he found out the the "six-inch rule" wjuld disqualify the majority of all CL handles.  That shut him up right quick.

Where in the rules does it say that it only applies up to "the point of flexibility"?  The term doesn't appear in either the general or carrier rules.

The 6" handle rule as written is incomplete, because it doesn't define just what constitutes "the handle". Since it goes on to talk about monoline handles,  my impression is that they mean the rigid part of the handle, and the purpose would be to deter whipping as Paul says. Furthermore, the "industry standard" 3-line handle used in carrier and scale definitely exceeds 6" if measured from the grip to the end of the cables. I don't believe there was ever a reason or desire to render these handles illegal. Looking in the 1964 rule book, the 6" rule is only found in CL Speed, reinforcing the notion that it is meant to deter whipping. If you choose to ignore everything except what the specific rule says, then I would say that the cables are part of the handle. They are not part of the lines, and they are not part of the line connectors. Following this interpretation would have lots of undesired consequences. All that being said, Paul seems to be relying on rules that are not in book.

I will take it upon myself to submit a CL General rule change to correct this problem.

The root of the issue was the fact that another contestant falsely claimed that my PERMANENT leadout extensions were CLIPS.  Rather than admit his error, he proceeded to try to build a bogus case agaisnt me.  He ended up opening a can of worms that, if taken to the extreme, would have disallowed the majority of the handles in use.

The concept of the rigid handle and flexible leadouts is not mentioned in the rule books.
In the absence of a rule to the contrary, everything is legal.
We need to just get along and not try to win by the Tanya Harding approach.

The rule book uses the term connector.  Your extensions are clearly connectors.  What they wanted to describe were clips which implies temporary or removable. Connectors imply permanent. They were limiting removable but used a word that covered both.  They should have uses the term "Clips" and actually (OMG) defined it. What you have done is fine from a safety standpoint and most likely in the spirit of the rules.  But NOT in the letter of the rules.  There is a reason for not allowing multiple connectors/clips.  They can easily snag.  Your "extensions" do not have that problem because of the heat shrink covering them. Let Bill sort this one out.  He will get it right.

Careful about analogies. Tonya had nothing to do with the attack on Nancy.  It was her trying to defend her ex-husband that cooked her goose.

I have reached the conclusion that we actually need two different rule proposals to solve this problem. First, all evidence suggests that the 6" measurement for the handle should be to the point of flexibility as Paul stated. While the AMA rule book does not specify this anywhere (so it's not a rule), the term "point of flexibility" is found in the F2C Team Racing rules. Again, the point of a maximum length restriction on the rigid part of the handle  seems to be to deter whipping.

The other proposal will deal with the permanently installed extensions on the handle cables. As this would be a safety issue, the legal eagles at AMA may want to get involved. At any rate, it will be a decision about what is or isn't acceptable in the future, where the 6" handle proposal is more of just an interpretation of existing rules.

I just measured the Brodak stunt handles as well as several other commericial stunt handles and the J.Roberts 3-line handle. 
They are ALL illegal if the flexible leadouts need to be within the 6" limit.
They are all legal if only the rigid part of the handle is measured.
This issue only surfaced when a Tanya Harding-style contestant tried to get my equipment disallowed.  The end result that if accepted, the majority of handles in use would be disallowed.
I intend to submit a rules change to put  lid on this.
In combat, stunt, and scale, whipping is OK and there is no need for such a rule.
In speed, the pylon prevents whipping.
In racing and carrier the judges can penalize whipping, regardless of the handle size.
We do not need senseless rules that can be used as the basis for crank protests.

Oh my dear Paul, what have you started.....again?  Pete and I were the designated ED's for Carrier and both of us are CD's.  He was responsible for the nitro events and I was responsible for the Electric classes. This was so as he didn't fly nitro classes and I didn't fly electric classes.  I noticed Paul's rube-goldberg line clip/extensions and brought it to the attention of my co-host ED.  I also consulted with other well respected CD's on-site to gain further insight.  Fine, now you have two fellow entrants to hate on. It would help explain why we were so against Paul's "extensions" if you would look closely at his pictures.  A picture is worth...well, you know. With the complete covering of the extensions with shrink tubing, there was no way we could inspect what was hidden.  As for the "extensions", they connect the handle to the lines, therefore they are "connectors".  AMA limits them to two per line.  We tried to make you understand our concerns but, as usual, you knew better and let EVERYONE know how you were mistreated. Be that as it may, come back to the NATS next year with properly constructed lines and all will be fine.

Rule reading for folks still interested.  In the Control Line General section, one will find the following:
"3. Size and type of control line handle
The handle shall not exceed more than six (6) inches beyond the hand of the operator..."
Note that it does not refer to the cable, just the handle.  A three-line handle measures 5 3/4" from the center-line of the grip to the front edge.  It measures 3" from my fingers to the same edge.  No problem with existing three-line handles.

"5. Size, construction and measurement of control lines
Control lines shall be of uniform diameter from the leadout connection to the handle. No more than two (2) connectors may be used per line."
That would disallow the "extensions".

Interesting. I see both sides of this debate / confrontation. If I were CD I'd want to see what's under the cover. Short of that, I would 100% side with the decision of the CD's making the call. It's totally not clear without seeing the construction. The rule book has no real guidance on acceptable "splicing" and leaves the interpretation up to the CD to make the determination. I think the rule that says no more than one connector includes a splice as in the lowest level meaning of connector is a method of making a connection. A splice is another connection therefore falls under that definition. I don't think it is relevant in those terms whether the "splice / extension" held the pull test.

My question is after the first iteration, why wouldn't one simply A) make a new set of lines that fit the rules for that airplane or B) make a new cable to fix the handle. The latter would be as easy as the extension. This totally eliminates the debate. It's also what I personally would do. In reality though, I would have simply done A before ever showing up at an event. In cases such as flying where speed is part of the score, handle and airplane will be to the rulebook line length to + o.nexttonothing and -0.0.

When I quarried Grok on this there were zero iterations that didn't use connection and the first query of what is a connector used in structural load bearing applications, the quick disconnect connectors was not in the reply.

"A connector on a cable that carries a structural load is the end fitting (termination hardware) that attaches the cable to a structure, another cable, or a piece of equipment so the tensile force in the cable can be transferred safely."

"In structural language these parts are often called end fittings, terminations, or tension connectors. Their strength, ductility, and alignment are critical because a single connector failure can unload the whole member."

I followed up with :

"So both the fixed / permanent devices are both version of the noun connector?"

Grok Reply

Yes. In ordinary use, connector is the umbrella noun for both.

People call all of the end hardware "connectors" or "fittings": the permanent termination on the cable and the pin-type piece you can take apart. That is normal and not wrong.

The tighter language, when someone wants to be precise, splits them like this:
              -   Termination / terminal / terminator — the device that is fixed to the cable end (swaged socket, poured socket, swaged stud, and so on).
              -   Connector — sometimes reserved for the linking piece that joins that terminated end to something else (shackle, pin through a fork, link).

Even then the line is blurry. An open socket is both: it terminates the rope and connects with a pin. Product catalogs still list sockets, forks, studs, and shackles together as cable connectors.

So:
      -  Everyday speech: both are connectors.
      -  Spec writing: "termination" for the permanent end fitting, "pinned connector" or "detachable connector" for the one meant to come apart.

The devices are different in function; the word connector can cover both.


After this dialog my mind is made up. The handle splice falls under the definition of the noun, connector, therefore splices are not allowed under the AMA safety rules. Get over it and fix the handle.

I don't think it's appropriate to publicly ascribe evil intent to an ED who's also a competitor.  If you truly feel that the ED was making calls for personal reasons, or even if you think they're making wrong calls for honest reasons, then you should take it up with the CD first, and then if that fails the AMA.  Before you do that, however, you should consider that the ED is supposed to be there for every competitor, contest worker, and bystander -- not just you.

If you want a rule to interpret, here's one that I think trumps any argument you're making -- regardless of any minutia about handle length or number of connectors or flexible part or rigid part.  On page 6 of the AMA general competition regulations (not even CL -- just general competition), there's this:

QuoteIn order to effectively oversee conduct of an event, the CD is granted specific authority
relating to organization, rules, and safety. In addition, the CD at an AMA sanctioned
event has the authority to perform safety inspections of any equipment and to prevent any
participant from using equipment which, in the CD's opinion, is deemed unsafe
.
Furthermore, the CD shall have irrevocable authority to disqualify or prevent from flying
any participant whose ability is, in the CD's opinion, impaired by the use of alcohol or
drugs.

So whether or not the handle was the right size, or had the right number of connectors, or is made from all the right materials, or absolutely any other consideration, if the ED looked at it and said "that's hinky, I don't trust it to hold together" then it's not only within their authority (at least as reflected from the CD), it is their responsibility to bar the thing from competition.

Frankly, as a sometime stunt ED, I may have made the same call -- regardless of how you define things, that not only looks like an extra-long line connector that's covered with some heat-shrunk plausible deniability, it looks like a potential workmanship issue that can't be inspected.

The problem with electric is that once you get the smoke generator and sound system installed, the plane is too heavy.

But wouldn't you agree that the CD / ED / Judge should be truely impartial ie. not having skin in the game / being a current participating competitor in that particular event ? Otherwise its like having a racing driver (who was also a race steward) that finished 2nd judging who actually won ! Its human nature not to be impartial if inside the competition!
