Another worn out pinion...

[popokatepetl]

Here's the 3rd party steel pinion if you don't want to wait.

When is official steel one coming? This is a big problem, mine is waiting.... so are many others...

[s0laris]

I have 40 flights on my goblin and as far as I can tell it looks good still. But I did not do the wd40 breakin.

I've heard that before and rest assured your pinion is being eaten up. There has to be backlash when you move main gear via main blades and it will only increase the more flights you throw on it. And that's with wd 40 or none.

[Tohtori R]

my first pinion lasted 34 flight before it was completely worn out!


i have pinions but it's not right to have to replace that in every 35 flight or so...

lets hope that they make planty of those steel pinions and that they last.

i dont understand this problem at all, testpilots have tested this heli hundreds of hard flights before it has published and still this kind of faults. not a big deal and they make alternative parts fast but still...

yes i have read this thread from beginning and i know there is an steel version of that pinion coming soon.

what i dont understand is how this aluminium pinion design has ended to stores anyway becose there is test pilots like Bert and Tareq that test these helis hard and long before releasing...

dont get me wrong. i really like my goblin and this is not a big deal. i just dont get it...

[s0laris]

You see how hard they fly. My guess is they test for stress and high rpms.

I don't think they logged enough flights before they needed to be rekitted long before a pinion could wear out

[Bert Kammerer]

Guys, the original pinion that Tareq and I flew and tested was made of a slightly different aluminum alloy. The first batch of Goblin helicopters that was released had this "good aluminum", then for some unknown reason, our vendor changed the compound without letting us know Now, we've decided to make a stainless steel pinion that will simply last forever by-passing any possibility of vendor error

Hope this clarifies the doubts.

Wow, I really think this amount of feedback from a company is unparallel in the heli community, and most other community as well. I really appriciate you taking time to keep is informed on all the topics we are discussing here Bert, and I'm just so very happy I decided to trust SAB and buy the first batch of Goblin's. If the weather permits, it's gonna be flight #200 anniversary today

[luckyflyer]

When will they be available?

[Bert Kammerer]

I was told last week in June, allow a few more days of course as it has to be routed through the proper distribution channels.

[s0laris]

what size comes with the base kit ?

Team pilots will log an insane number of flights before any kit goes public.

Unfortunatly this seems to be happening more and more. A company does all the necessary R & D to develop as close to a bullet proof product as they can. Then the designed parts go out to mass manufacturing. Then after a while one of the mass manufacturing facilities decides to change material or design without the original engineering companies approval for reasons unknown. And the end user assumes it is a design flaw on the product companies end.

Thank you for the honest post Bert.

Unfortunately this happens all the time

[windwizard]

Thank you for the "official" feedback Bert!


I just had a quick question, what proceedure should be used for seating/breaking in a new steel pinion with a new main gear?

Same as before, (WD-40) or ...?


Thanks ,

This supplier wouldnt happen to be in asia would they (assuming you know and can say)? Its pretty common there. I hope its not spreading to other parts of the world too.

[Bert Kammerer]

It is spreading everywhere

No break-in required with steel pinion, no grease or oil needed either

I've got a spare main gear just waiting for some steel great job Bert and team sab
