    Glad you were able to correct them this nicely.

    Nice work, Eric. It's always a tough decision to undo work but I find afterwards I'm glad I did..."sounds" like you are too. Looking good...keep 'er going!

    Nice job ! Looks very nice. Now you can finish up with your "H-100" like you originally planned. I also personally like how the Corsair looks with all of these cooling flaps opened up like how you have done here with yours.

    You can see it in the original photo you posted, and it's parked behind the H-100 Corsair that you are building. I like the "H-96" in the background too.
    Both are very cool planes.


    As far as these upper cowling flaps go, they were changed from a hydraulic system to a mechanical cable arrangement starting with Bureau Number 02578, which was the 426th Vought Corsair built. This was because the original hydraulic cylinders controlling the cowling flaps often leaked oil, and it blew backwards onto the pilot's windscreen impeding the forward vision. I'll have to check and see when the change happened with the Goodyear and Brewster versions.

    Then later on, they came out with a field modification that was supposed to be retro fitted to all aircraft in the field as well. This modification secured the top three cowling flaps in the lowered / closed position. This is why on most of the later pictures we see showing early "birdcage" Corsairs in service, they have these top three cowling flaps secured down. It was implemented as a standard change on the production line then too. On the field mod, it was a stamped piece of heavy gauge aluminum that was secured on top of the cooling flaps, holding them down.


    like this one shown here.

    I'm definitely looking forward to your next installment. That's an incredible photo of H-100 in several aspects. It's an early Corsair, the cooling flaps are all still open, and it has the red surround on the US National insignia. It doesn't get much better than that.

    Windscreen Prepped For Paint

    As I move towards the paint shop I masked off the birdcage canopy with the rear view mirror bulge and the windscreen using the Eduard set I had acquired years ago. I followed the kit instructions and attached the armored glass in front of the gunsight although I am not sure if the early F4U-1 actually installed these. Then I painted the windscreen frame that early interior green so that it looks painted on the inside of the cockpit. Using white glue and a couple of drops of foam safe cyan glue, I attached the windscreen to the fuselage and stuffed the cockpit with shredded Kleenex to keep the overspray out.

    Almost ready for the paint shop except that I noticed that almost all Corsairs have their wing flaps in the "up" position when parked. Tamiya's inner wing flaps are designed to be modeled only in the "dropped" position. Even if you cut the flap attachment points off, you cannot position them in the "up" position correctly. Ultracast resin to the rescue! Until these pieces arrive, I'm stalled. Guess I'll get back to fussing around with the rather difficult DoraWings' Curtis Jeep I've been working on until those Ultracast parts arrive.

    Looks great, Eric (@eb801). It is hard to go wrong with a Tamiya Corsair. Interior looks really nice. Interesting approach to prepaint the canopy.

    Nice progress. It's hard to beat the Tamiya 1/48 F4Us for ease of build and great result. Do remember to fill in the step in the right inner flap - that was a postwar phenomenon.

    The cowling turned out very well. It looks good ! Good call on the flaps too. I like how the Corsair looks better with the flaps dropped, but more often then not, they were parked with them raised.

    What about the canopy, Louis@lgardner? It looks to me like the canopies were left open when parked on the tarmac or elsewhere to speed up things up, but closed when the wings were folded. Any word on this?

    Thanks TC@tcinla: I had already filled that flap step on the Tamiya part but I will make sure I do again when the resin replacements arrive next week.

    TC: Do you know anything about these new Chinese tooled Magic Factory 1/48 dual F4F-1A/2 kit which I believe has just been released?

    I have seen pictures of the canopy closed when parked more often than open.


    This was more common in the SW Pacific. It helped to keep the rain and coral dust out...

    Either way will work though. I don't think it mattered if the wings were folded or not.

    The resin flaps will not need filling in. It's already done for you... at least on the sets I used in the past. Notice these Corsairs have the flaps raised too. They could have been left lowered, but it seems more often then not they were raised before the engine was shut down.

    Thanks for those two photos and comments Louis@lgardner and John@johnb. After all the yak yak about open vs closed canopies, it really doesn't matter which way it goes, does it?

    Flaps UP!
    Much to my surprise, the Utracast flaps arrive a few days after placing the order, so here they are installed. You're right, Louis, the step is filled in. These flaps installed easily and the fit was darn good. All I had to do was add a little cosmetic gap filler and bits of stretched sprue to simulate the actuator rods on the flap bottoms. Off to the paint shop now!

    This looks really nice ! I am a big fan of using Ultra Cast stuff. The Corsair flap set they offer is excellent.

    I just left a detailed response to John's Corsair about the flaps and the canopies about them being raised or lowered, open canopy or closed.

    You are spot on... it didn't really matter and the pictures show this. But we do see more Corsair's with the flaps raised during the War though.

    Build it to suit your personal taste and have fun.

    Excellent so far, my friend @eb801! Looking forward to the painting!
