JF F4U-1 Corsair 'Birdcage' released!

My observations on the prop effects...with FSXA

The first thing I noticed was the transparency. In daylight there seems to be some reflection whereby the prop seems to be whitish from the VC or back while the front is darker. As the plane flies relative to the sun, the reflectivity changes. It's not a major issue until you do some night flying. It was challenging to see the runway lights through the prop.

The second thing I noticed was the rotation. It does rotate, but much slower than expected. I would think there should be noticeable rotation at slower rpms with increased rotation and more transparent at higher rpms. Just my opinion.

This are taken with P3D v 3. Doesn't look right. And I entirely agree with the remarks about rotation, little or no speed variations, however don´t know if this looks authentic...

I would still refer folks to the best prop discs in the business, and that's the Warbirds' P51 series of aircraft. I also like the A2A P51 work.

Here are 4 shots which I hope will highlight this very odd prop.

In this one and shot 2, the arrowed area (the darker, inner blur) moves very slowly.. almost like an FS8 to FSX portover. You see the grainy area and you can follow the individual texture left to right. You also see artefacts of what I presume is the volumetric effect.

In the outside (rear to front) view.. the volumetric effect is much easier to see.. ghostly outlines of 3 blades in each of the 3 shaded areas of the blurs..

I mentioned the prop and it's apparent lack of speed change regardless of throttle and/or rpm setting very early in the thread and having since watched a fair bit of Corsair video to confirm my thoughts.. on the real thing (especially on startup and taxi out vids) you can see it changing speed. Granted.. the vids I've watched have all been for the 4-blader but I can't see this making a great deal of difference.

I don't have this model but may offer just my 2c opinion on this. Prop blur in videos is nothing like how it looks in real life because of the strobe effect, dependent on the FPS of the video camera. At least when behind a Cessna prop all one sees is a slight blurred disk, almost transparent. IMHO, effects showing blade shadows in a sim plane only make for photo-like screenshots and cine-type videos.

Taken as read mate. If half the sim models looked like some of the vids online (particularly digital).. I'd have very little on my HD:biggrin-new: However.. if you discount the poor vids, there are still enough out there to give a realistic representation of the real thing;) The point of searching for vids was to confirm (or otherwise) what I've seen in real life many times (eg, Corsairs flying) though not, unfortunately, from the pilots seat;)

I can't find the block on the starboard wing that modified the stall characteristics

Early model F4U-1 Corsairs as the one modelled were not yet fitted with the wedge spoiler. They were instituted on the F4U-1A along with several other modifications.

That is quite possible and I know I've seen information on British fixes (besides the clipped wings, canopy, cowl flaps and a few other things) but haven't been able to track down proof positive regarding the spoiler in all my reference material. If I come across it I will be quick to post it.
 
The whole 'early era' is a bit of a minefield me thinks. I've good shots of later Corsairs that don't have the wedge spoiler but that said.. finding a decent shot of a Corsair I Birdcage with clipped wings has been fruitless. There are plenty of drawings/plates of the Corsair I with Birdcage and clipped wings but few (if any) actual phots. All the shots showing (clearly) clipped wings have the later Malcolm type hood with 2 frames over the top making them Corsair II's or full bubble canopies making them later versions.

My research indicated no stall strip with the F4U-1 which was still undergoing testing through March 1943. According to test pilot Boone Guyton in his book "Whistling Death" there were a series of tests on various length stall strips though that time period as a prelude to the next variation the F4U-1A. This was confirmed by my second resource which states that the deployment of the F4U-1A included "Directional stability for landing was improved by increasing the height of the tailwheel leg, changing its tyre from a solid to a pneumatic type, and adding a small spoiler on the starboard wing leading edge."

Keep in mind that once the solution to the technical problem was found, many earlier models were retrofitted in the field. I didn't find any reference to the stall strip being used by the Royal Navy with the Corsair I's. Just a guess but because of their shorter wing spans, they may not have experienced similar problems with the left wing stall.

Least that is one book I can pull off the shelf and the photo is colour .. I better do that very thing and check to see if there is a wedgie .

There we go , a later Royal Navy Corsair , it has the Malcolm type hood and the Wedgie making it the later MkII aircraft.
 
The early Birdcage F4U-1 , of which this model is an example did not have the wing modifications. Forget anything with a bubble canopy or smaller intake mouths, or any other of the numerous field and development modifications. This example intentionally portrays the earlier aeroplanes. BTW, The tailwheel was optionally pneumatic OR solid, depending on the deployment of the aircraft as it altered the angle of attack when on the ground/deck. We do do our research.
