Okay, don't (please) as why I need to know this, and think I am already headed for the inevitable, but anyone know what material the clutch shoe is made of? Please don't just answer "steel", I'm interested in a bit more detailed info so I can look up material properties.

Like I said, don't ask.

Related question- i've read about clutch shoes of this type being "sprung"- the slot gaps too large. Why not just press them back to spec? Hmmm, I've perhaps divulged too much already...

Thanks all-

Never, ever, ever, ever give up.

Why do you want to know?

I had a slip of paper with the last clutch I had saying to press the shoes back together to maintain a gap of 5mm every 20 or so flights, so I assume you can reset them.

Goodluck with whatever it is you are doing!

Thank you for the reply, Ben. Interesting info- was it a Kyosho clutch? Maybe resetting the clutch is normal practice, I am new to nitro helis, but from my reading nobody else mentioned resetting the shoes.

Why do I want to know? Basically because:
1. I am a cheap assed bastard and didn't by the proper crankshaft locking tool before attempting to remove the clutch shoe from the engine

2. I am a cheap assed bastard leading to my wanting to repair said clutch after may lame attempt to remove it from the engine without the proper tool (see number 1 above).

3. I am also interested in these things, like maybe we could use a better material for the clutch and they would last longer....

There, I've spilled the beans. I bent one shoe out accidentally, and it was easy enough to straighten back to position, but then I began to wonder about what grade steel we have here and if that first plastic deformation (yielding) did it in for good and I'm gonna destroy the clutch and housing on the first fire-up.

Either way, I ordered the new clutch shoe. Ho, hum.

Never, ever, ever, ever give up.

what material the clutch shoe is made of?
Dollar bills. Less than 4 of them.

CA3016-01 or CA3016-01A.

Reset the shoes every 20 flights? First time I've ever heard that tune and I've been through a bunch of helis in the past 30 years. In that time, I've had ONE clutch problem, that was an EVO 50 where one of the shoes just broke off, that was this past summer. My 6 year old Caliber 30s are still on their original shoes and linings. Never a problem.

If you've "sprung" them (bent them way out), it's time for a new clutch shoe. You've not only weakened the small part that connects the shoes to the rest of the clutch material, but the two halves will no longer have approximately the same amount of "springiness" to pull the damaged shoe back in. Eventually the shoe will probably break off, and in the meantime you'll most likely end up with a grabby clutch that drags.

Clutch shoes price at over $20 plus shipping wherever I look and I have to wait. I was thinking of flying that bugger today, but I'll wait for the parts.

Liner is less than $4 if thats what you meant. I suspect you are right about having changed the spring rate of the one shoe side- probably not good.

However I could put the thing through a heat cycle and likely get material properties back to original. I was surprised at how easily it bent.

Thanks all.

Hi Matt

I remember to change 3 clutch shoes and lining from my first Caliber 30, the problem was not the shoes, there was the plastic clutch bell, problem gone when I found on a Japan store the metal replacement.

I read later on posts that it appears to be two kinds of clutch bells for the Cal 30, one made in Japan with an copper ring inside plastic, and the newest ones made in China w/o the ring, pure plastic.

Recently I buy some spares for my Cal 5 and compares between the japan and china made, in my opinion china spares are lesser quality and are made from a different (cheap look alike) material.

Why don´t you try one C5 clutch bell?

I might but at this time the clutch bell (newly balanced by me) and the liner are just fine. I damaged a shoe during my lame attempt at removing it from the engine, hence my unnatural interest in what material it's made from

Thanks for the info- the Cal 5 bell might be a nice upgrade at some time.

Never, ever, ever, ever give up.

Some how I read that as what material is the clutch LINER made of, not SHOE. What a goofball I am! Well, the answer was still fun!
