Rotor heads Please price this part.thanx

So you know he's shady enough to cancel an auction and sell you something out from under another bidder, but you trust that he's not lying to you on condition of the part?


Please don't fly this near anyone I care about.

Sorry, P4L has it exactly right.

Why the hell would this guy take a lesser offer from you if he has an eBay bidder in the $12k range???

Wow dude, switch to decaf or something.

Riddle solved.
Hughes made a Gyro in the late 1960-1970s ( J 2 rare )
They used the exact same rotor head as in their helicopter ..But, its not marked with a 269 part number, relegating it to part that looks correct, is correct, but not usable at any price.

Just to further some transfer of knowledge here:

Although is has in the past been a practice generally accepted in the industry, tags mean "f**k all" to the FAA. Many parts to this day are advertised as "yellow tagged" and this is understood to mean that the part has at least been inspected and verified as good to be reinstalled - HOWEVER the tag alone is not an FAA legal document for that purpose.

Each Part 145 shop will have an "accepted forms" manual, that is forms used by their shop and that the FAA has found acceptable. However they mean NOTHING once they leave that shop. They are for identification in the shop. In my shop, yellow tags identify military parts, green tags identify civilian parts, and red tags identify FUBAR parts. In my shop, they do not indicate if the part is good or bad, only what the nature is of the parts usage. And that is the FAA Acceptable usage of tags and tag colors for my shop. For "return to service" for an item coming from a shop, you should have an FAA Form 8130 or at the very least a shop work order with an FAA acceptable release and return to service statement on the work order.

For a used helicopter rotor head, you should have a Component History Card for each and every life-limited component. On a Bell 412 rotor head, I have a card for each of the 8 blade retention bolts, a card for each of the two yoke plates, a card for each of the 4 spindles, a card for the upper cone, a card for the lower, a card for the cap, etc, etc. Every single card should have entries on it showing the life history of the component, including hours in service, inspections, etc, and a final entry that shows when and why it was removed.

For a used Hughes 269 rotor head, you should expect similar documentation.

Thank you.
If you run across the 3 or 5 blade head, bused, timed out what ever, i would love to rent part of it for a six or seven days.
This part for the Hughes has been a rough road to figure out.
AFAIK its worth its wait in scrap, or perhaps a few bucks to J2 guy.
Thanx for the help!

Unfortunately for you (or fortunately for me) I do not work on Schweizer or MD helicopters.
3 blade heads are Hughes 269, 300 / Schweizer 269, 300 / Sikorsky 300C, 300CBi.
The 4 blade rotor was Hughes 369 and 500.
The 5 blade rotor was Hughes 500D and later MD 500D, et al
I think the MD 600 series uses 6 blades.

Well........if you stumble upon one or part of one, please let me know.
We have prints and drawings here...still I would like a hands on examination to make a scaled dwn version.
Thanx

Have you thought about this?
Much, much simpler.


Are you not worried about patent infringement lawsuits when you rip off somebody's design and stick it on an experimental?

Here is a thread you may have already seen:

There is no patent problems if someone copies a product for personal use and not resale. ( at least thats what a couple attorneys told me years ago )
I have not thought of the above rotor head at all, I have seen a couple pix, but I thought is was RC stuff.
I do like the lead lag simple design and dampeners .
Found it.
