New 1/32 F-4K/M (FG.1/FGR.2) Phantom kit announced by HKM

A derelict US Navy / Marines bird, which shows angle of MLG legs - unfortunately too low res to help with a NLG comparison.

The lower portion of the NLG is angled back, but the leg appears perpendicular on other variants (pics drawn from the web for illustrative purposes only)...

Needs further investigation

Last thing I heard was of May this year, there were 2 Phantoms hangered at RAF Leuchars they were Black Mike and a grey camo FGR2. Now the Army has the base so I don't know what will happen to them but I think they are still there.

There are others a little more accessible than Leuchars. I took some shots of the Yeovilton FG.1 a few years ago, as have a few others here. Hendon and Duxford also are on view, but there was talk of a gaggle of LSP'ers crawling all over another Spey Phantom with camera, tape measure etc.

This could get very interesting, since ZM has announced a Phantom and speculation has it that the kit will be a B. :hmmm:

1/32?

1/32?

 

Doubtful. They are still in the process of recreating the Focke Wulf 190 family tree in 1/32, last time I heard. The Phantom series is all quarter inch to the foot sized.

The F-4 nose gear is hydraulically steered, not castoring though...  I'd think the hydraulic pressure would be adequate to prevent unwanted castoring.  I love figuring out new stuff about this amazing girl all these years later!

Correct....the caster is accounted for in the lower piece that the axles are located on it angles aft with respect to the strut C/L and can be seen by referencing the axle C/L to that of the strut. Also when the gear is fully extended it is mechanically centered to ensure that the wheels are positioned straight ahead for touchdown. Once there is weight on wheels the mechanical center disengages allowing the Nose Wheel Steering collar to hold wheels centered. The last thing you would want would be for the wheels to be even slightly left or right of C/L on touchdown. If both tires did not blow immediately the ride would be most exciting!

Actually Barry aircraft land quite frequently with nose gear out of Center.

Friction quickly centres them with a fairly hard thud on touchdown.

There are frequent issues with nose gear systems keeping gear aligned. Frequent!

Occasionally a more substantial alignment issue can occur leading to loss of rubber and a fair bit of smoke.

Aviation tyres are pretty tough.

All of our aircraft "Gulfstream" have a mechanical centering lock internal to the strut. When the aircraft is weight off nose wheels it is not possible to move the nose wheels out of centered position. It is true that often the NWS will not track true without pilot input and we have had many occasions when NWS was engaged when the centering lock disengaged that the aircraft has veered hard left or right . We had an aircraft in Spain a few weeks ago that was taxing slowly in extreme rain and the pilot lost his bearing on the taxiway and jammed on the brakes and blew all 4 main tires. The tires are multi ply but not impervious to abuse!

Excellent news! I have been planning on hacking the Tamiya F4J into something similar to an FG1 for many a year now, so will now cancel that. I can spend the wait on the Echelon Lightning, or the Revell/Fisher Hunter T8. Happy days!!

Clarkeeboy do the Echelon lightning and start a thread. I've built a load of these kits and I'd like to see your take on it.

You'll enjoy it.

Nice idea Dave (what I wouldn't give for an Echelon Lightning (or Hunter) kit :) ).

Thank those Gulfstream tyres need some work.

Our Airbus and 787 tyres take quite a pounding particularly nose wheels.

The A-320's frequently land with nose wheels out of Center which causes a lot of wear and decentering.

All our aircraft have anti skid so lock ups are not an issue.

The Jumbo has a reputation for Nosewheel steering alignment issues.

Our tyres are double layered steel belts so made to rake a pounding!
