FSX: The 1940 Fokker T.5 bomber released

Hi all,

Beta testing is well underway. There's roughly 15 items to be addressed. Some are details, but the major thing is the sytems modelling.

I've modelled most T.5 systems from what I knew (from the handbook) with the means that I have. So the systems modelling might be accurate when following the written route, but is not robust and difficult to understand and perform correctly.

I will improve this, by making it less complex. This will probably go at the expense of systems depth, but better a more robust system.

So far, it also works fine in 64-bit P3D, with the only change being the sound gauge of Dawson.

If things run well, it might be released this year.

Cheers, Daan
 
Haven't been commenting on the thread much, but I love seeing these updates. Dutcheeseblend, fantastic work on this plane. I love how much detail you put into the interior and look forward to flying her. Truly stellar and inspiring work, you really motivate me to work on my own models, knowing that aircraft of this quality are possible in FSX. :encouragement:

Well done, mate!

Thanks Maty! I love to read that!

Meanwhile...writing the manual...

No problem Huub!

Now during flying this plane, we remarked that the airspeed indicator is only used for the first half of the range (0-650 km/h), and that the stall speed is one third below the first major tick (150 km/h while landing speed is 105 km/h). During writing of the manual, I found out that the installed airspeed indicator should have had a range of 0-550 km/h, which is confirmed by photographs. Also, the first major tick is at 100 km/h, making it more convenient to read in the critical regime.
By the way, I just finished reading this book: https://geromybv.nl/home/silent-key-cornelis-a-hoefnagel/
It's about a former T.5 radio-operator, who stated that T.5s reached 500 km/h (indicated) during dive bombing in the war. He also described that these dives were ended at rooftop level. In his own words, the T.5 was 'een trouwe machine' and that's one of the few positive words I've ever read about the T.5. The only other positive words are that it performed better (in airspeeds) than predicited during design phase.

So I found out that I still used the D.21 airspeed indicator. Therefore I converted it to the T.5's range.
Probably I need to redo the RPM-indicator as well, since it ranges from 0-4000 where it should 0-3000 (according to images since the manual says it's reading 600-3500).

For the release, I probably will make an introduction video. Although I've written down everything in the manual, it's just sooooo much. I needed twenty images to describe the interior's functionality.
One thing that comforts me yet, is that everything works as it did on the real deal.

Cheers, Daan
 
Although I had a quick look and noticed there was no interior in the bomb bay, I did not mention this. There were two reasons. How many virtual pilot will actually look in this bomb bay? And the other reason was that it is actually quite authentic. As there were severe problems with them and I understood that not all had been delivered and/or installed in May 1940.... :biggrin-new:

But as usual, the racks look pretty good. :encouragement:

Cheers,
Huub
 
Indeed, to me it's still unknown which T.5s flew with which type of rack: the Dutch or German one.
And neither did I draw a solid conclusion on the bomb load.
I eventually came up with three load cases:

A: two bombs of 500 kg
B: four bombs of 200 kg
C: sixteen bombs of 50 kg.

So that's what I modeled. Testing the visibility logic right now.
 
Also added a bombsight using the functionality of FS9VIEW. Unfortunately, I could not render this view on a 3D poly (as I wished to plot it at the model of the instrument), but well, guess this is enough.


You could adjust its angle as well, with the knurled knob at the right hand side of the model.

Here's the first instructional video: how to start the engines.
For the beta testers: this is after the changes suggested by you. Some things might not correspond to the beta you have.

 
Just published the second video: taking off with the bird.


I expect a lot of comments about the take-off. Yes, original handbooks show a take-off run of merely 220 m with MTOW (some 7500 kg).
