It seems to YOU (gearhead) that every incident that ever happened was documented on the web, so now if i search and don't find anything it means that nothing ever happened?

The nature of this issue is such that the heli self destructs in mid flight. If you don't have experienced people there to know what exactly happened it can be mis-diagnosed as something else. It has happened before! I guarantee it.

Gearhead, where is your common sense?

You can see the century GOONS all coming out of the cracks now trying to uplift their god father BILL MEATOR. Is it meador or meator...lol pls correct me if im wrong.

you broke a grip in flight, it has happen with all brands, I have had a Raptor thow a blade, so I have seen it,
you said yourself you were turning a HS as much as 1950 with 720 blades, you were pushing your luck, where is your common sense?, as Bill said you should have been using metal grips not plastic grips

you push your luck anytime you go out to fly. OK? I would really like to see you guys in person just for laughs. No common sense at all coming from gearhead or Bill Meador.

Even if its the logo XXtreme. Okay? So please come up with something new.

Well you are acting like a goon, so I will label you from now on as a goon.

common sense
common sense tells me that if you broke a plastic grip with 720s at 1950 you should have been using Metal Grips

I think that is a lot of common sense

WHOA WHOA WHOA!

what the hell does any of this have to do with MY clutch issue?

Please guys...if you want to argue about HS, blade grips, and brand quality, please open another post and do it there.

BTW, I welded the weak portion of the clutch shoe (Not the flex point), and welded layers to make it thicker and therefore stronger

the two pictures below show two clutches...
the one on the left was a quick and dirty test. it was welded with thicker arms, and balanced (but not really cleaned up )

the one on the right was also welded, thickened up just a bit and cleaned up, balanced. This one is the broken one in an earlier post BTW.

they both work well and show no signs of cracks, each has a gallon thru it at high RPM...think my problem is solved.

thx guys,
so far so very good, flew it again today (not in ideal weather) with a HS of 1950 and 13T pinion....

the clutch is holding very well...my guess is that the extra small hole inline with the flex oval was creating a weak point overall.

the weather here has been wet, cold, windy and misserable (it cleared up just two hours ago rain wise)...so guess I will spend the afternoon with the dremel and clean up the clutch on the left side of the pic, and spend another evening balancing it.

the Mig welder I have just makes a mess (slag and splatter) especially on small parts...

plan on picking up a TIG ive wanted in about a month or so, then I can weld up everything metal that breaks without the mess...

I really doubt it will break again, as the arms are much stronger now.

Your MIG will collect dust if you get a TIG! Mine does. I originally cheaped out and got a air cooled torch for the TIG. I finally built a water cooler and it transformed the weld quality and capability.

Did you reline the clutch and decrease the gap? The gap can cause too much flex.

yes...and that was some what of a pain.
after tacking, welding, cleaning, turing on the lathe, adjusting, rebalancing and recutting a new clutch bell....

talk about a LONG way around fixing a broken clutch...but hey I had the welder...it was raining all dang week, and I didnt have to buy another freakin clutch.

can't wait for the TIG, Haven't seen it yet but it belonged to an uncle that passed away, he had money and bought good high quality stuff...Miller or Hobart hopefully...

Thx fastflyer for the heads up on the water cooled torch, I hope its also water cooled...

Welding
Not sure I'd like to weld a broken clutch back together. Isn't it better to just get a replacement from the manufacturer?

How do you balance it? Did you drill holes in the sides to get some weight off the weld?

yes...if you have the $$$ and patience...and don't have a means to weld or skill....i didn't want to spend anymore on yet another clutch/shipping + time wasted waiting...(I had three broken ones)...besides buying another was not solving the weak arm issue these clutches have.

once welded (with the proper filler weld) the joint is usually stronger than the parent metal...especially after making the arms thicker.
How do you balance it? Did you drill holes in the sides to get some weight off the weld?
its balanced just the same as any other cylindrical onject on a high point balancer...but do not drill holes in it...its best to use a dremel with a grinding bit to remove metal in tiny increments from the shoes inside facing rim.

Now the only part I do not weld is the flex area between the clutch shoe and the Arm....weld metal is stronger but also harder and therefore stiffer...so it will not allow for flex to allow the shoe to engage the bell.

Dont worry RM3, not all of us are questioning you skills :-) .

If I was him... I would not weld up a broken clutch.... But if I was you I would without a doubt.

As I said.... Damn fine weld job. your skills are apparent to those that understand what they are looking at.

I have to agree, you did a fine job there, and I also agree that it is sometimes just plain fun to fix some things just because you can instead of throwing money at it,

to add, it's nice to know your fuel tank wont leak

BTW (RM3) sorry about the Hijacking there !!
