Hiya,

I'm about to install and OS50SX Hyper into my Rappy 30 after burning out the TT39. heh Yer its overkill, but the 50 upgrade is next innit. Why buy another 30 size if i'm gonna upgrade later anyway. Back to the point...

However The QUK heavy duty clutch does not seem to come with the clutch shim part BK0170. Mind you there seems to be a hole in the bag... it may have fallen out

Is this an important part or is it not needed for the assembly when upgrading the clutch? I guess I can always pull it off the old clutch, but it seems a bit fragile...

Cheers

If you were to use the quick uk metal fan then you wouldn't need the shim as is already machined in the top of the fan, Use the old tt one it can be removed from the old clutch using a knife.

I make the QUK clutch a routine upgrade, and have never had one fail on me. If you had the original fan, and "lost" the fragile shim, you can always file away the top of the fan hub that sits under the clutch shoes. Needs very little metal removed.

I wouldn't worry about the shim or filing a relief. IMO, it's a fix for a problem that does not exist.

I have to disagree, Al. Before the shims appeared (remember the old V1 fan hubs), the TT clutch arms would fracture, starting on the side away from the hub. You could actually see the arms distorted off horizontal, and the distinct scrape marks on the aluminium.

Anyway, QUK clutch and fan seem to last forever.

your correct, the TT clutch arms....QUK clutches do not experience this issue

Ask your Doctor if getting off your ass is right for you.

You are correct. The problem , however, was due to the very low quality of the material, not that the clutch shoes were touching the fan hub. A hundred different model helicopter designs used the same set-up, without clutch shoe fracture, and never had a shim. As rotorpsyco said, with the QUK clutch, you won't need a shim.
