Hinomary are easy, it is important to have unit markings

Well, the hinomaru project worked out pretty well for a first attempt. I doubt I'll use decals any more! Just a few bits to install and this one goes in the display case.

I also got the landing gear installed a bit ago. It took quite a lot of work to add all the plumbing and linkage to the gear. The N1K1-J had a very long gear and it double-telescoped to fit into the wheelwells. Unlike the P-47 design the Japanese engineers used hydraulics only to shorten the gear for retraction. That led to a lot of hydraulic lines and sequence valves on the gear legs. The N1K2 lowered the wing to the bottom of the fuselage and so dispensed with the stalky, complicated legs.

True, no matter that mid wing configuration gives less drag, more penalty come from the difficulties with landing gear. If you put it in wing, you need long strut and this mean weight and in other hand there is also problem where to put it in wing (this make another problem with structure stress and weight penalty). Other solution is to put landing gear in fuselage (like in Wildcat) but this give narrow track and this mean taxi problems. Options are inverted gull wing (like Stuka and Corsair), where on lover point is mounted landing gear or smaller length. As you guess- gull wing have this braking point which have to be secured by additional bolts and hinge and this mean weight penalty.

It was a real nightmare to make good fighter!

Thanks for technical details, Scott, and nice theory explanation, No.1 :-obey
Yep, BTW, nice hinomarus as well :-ok

The designers and engineers were certainly ingenious in being able to turn a floatplane fighter into a land-based machine with relatively small modifications. Certainly the gear ended up being a problem, but under the wartime pressures to produce the -J it's a pretty neat solution to the design.

Here are two photos of the gear on the prototype airplane. The first shows the strut in the fully extended configuration and the second shows just how much it telescoped to shorten it for retraction. You can see in the first photo that there are two strut cylinders, one telescoping into the other and the pair then sliding up into the upper gear leg.

The production gear is a little bit less complicated looking but still has quite a lot of plumbing on it.

Here is the N1K1-J. I picked this particular airframe even though I don't exactly know its pedigree. I had access to both left, right, and forward 1/4 view pictures of this bird and I liked the NMF lower surfaces combined with the standard top camouflage. The lower inlet scoop of the normal George is missing on this machine and there is no armament, leading me to believe it was a test ship for engine modifications. The main inlet is also larger diameter than the standard N1K1-J.
