KH 1/48 D/H Huey rotor head issues

Recommended Posts

Well it turns out they may not have gotten the scissors and push pull tube configuration wrong at all. I still think the stabilizer bar is too low. These 2 pics show them in a similar position to how the kit builds up. Must have something to do with collective or cyclic position.

Don't quite get what else you may be referring to but that head is a 540. That control  positioning is correct for that install, not for a D or H. Kitty Hawk kit as intended is wrong but I found the mast locator pin was a part of the o'clock issue and the drive links/scissors were backwards. If you had the opportunity to revue the maintenance books for this series of helicopters you would be surprised at the difference that exist between models. The 540 on UH series was a blend of the UH-1 and AH-1 controls.

Yeah, that's pretty exaggerated for the tubes. Look at pictures of B,C and M and that angle isn't as prominent. Must be something peculiar to the E with a 540 head.

So the Kitty hawk is still wrong?

Yes, the Kitty Hawk kit is wrong. There are incorrect presentations of both hardware and relative location of hardware.

I would give my eye teeth to see the maintenance manuals!

I have a set from 1989. If you want to see something specific I could go through the books and find it. Descriptive illustrations of each model contain multiple pages of parts breakdown.

Just interested in reading them in general lol. How can one get a copy? I still don't get how kh can get it wrong with knowledgeable people involved.

I believe they are available on disc, you might find them on ebay.

I think kitty Hawk got it wrong largely because the CAD designers did not understand what it was they were looking at. And I do not think the CAD designers are as fully capable as they could be. They designed the scissors and drive links and while parts are right, they are mirrored and no one caught that. The locator pin at the top of the mast and it's dimple in the head are placed improperly. While what they did would have worked it simply was not aligned with everything below it in the proper way. Some of the other things, like the overhead detail that was missing and the failure to put a locator for the transmission is just plain sloppy work. That seems to be a theme with practically all their kits. They also designed their mold poorly as we see the mold separation lines running down the lower fuselage halves. Just sloppy.

Yeah the overhead console is a bummer, and no stencils. I'm not in a position to purchase the Werners Wings stuff. Just had a 4th heart surgery in 2 years so got that to pay off, plus we just had to spend a grand on appliances that went south this month.

What really surprises me is these mistakes happened under Floyds watch. Are there any easy fixes for the rotor head?

I built one recently and I deleted the little pin on the top of the mast and turned the whole mast clockwise. Couple of little fiddly things to adjust and even though the scissors and drive links are incorrect the control tubes line up without that exaggerated tilt. Looks ok, someone who did not know about it would not realize it.

all has gone silent from KH on the 1/35 release also...

Typical of these guys.    If their past is any indication, the 35th Huey, if it ever arrives, will be nothing more than an upscaled version of the 48th kit, warts and all.   This despite the “new-tool” hype.

Reskit has announced what looks to be some really nice correction sets for the KH Huey on their FB page. Rotor system, complete interior redo and doors etc

Would you be able to post pics of how you have corrected that? Sounds like something I need to try on mine.

I'll try soon. My wife passed away suddenly September 18th and I am in deep work dealing with legal stuff.

What Chris said. How many degrees did you turn it? Getting anything aftermarket won't be happening lol.

I rotated it to a better position using the alignment of the control tubes as a guide. The damper arm links needed modification as well as the PC links. I also discovered that the stabilizer bar does not have proper mounts and the oil reservoirs for the blade grips are not there.
