Initial Release: Grumman Goose G21A Redux II

For this Goose? No.

For another Goose :duck: :relaxed::sunglasses: yes.

Spent a fun weekend flying this aircraft all over. One thing it might need is more differential throttle turning when on water. You need a whole lake to be able to turn this Goose 180 degrees, and it’s pretty much impossible to do on any river.
Here’s a real one doing some pretty sharp turns on water

Discussed at length throughout this thread :relaxed::duck::small_airplane:

The window frame crossing the glass is gone on the exterior. Is that supposed to be? Looks like a more modern one from the outside this way.

Very Nice Plane,
but same for me,no way to turn on Water,one on high it go straight forward…
so i can`t use it,i am sorry…

I have played around with the water steering the last couple of hours. I first thought I could add water rudders to the floats, but that does not quite work. I also tried to increase the rudder scalar, but that makes it nearly unstearable on a runway.

The best solution IMHO is to add a non existent water rudder. Do the following:

  1. Open flight_model.cfg in an editor (Notepad is fine)
  2. Search for “[CONTACT_POINTS]”
  3. Remove “;” at the beginning of the 2nd (at the bottom) line starting with “point.9…” (this makes it active)
  4. Change the first parameter to 4, read like “point.9 = 4, …” (turns the point into a float)
  5. Set “max_number_of_points = 10” (adds the point to the contacts points list)

Alternatively, replace the whole contacts section with the code below. Make sure to replace only that one section.

I think this is only an interim solution until water handling, prop wash and the model itself gets its next update. I sincerly hope this does not anger the creators, its just I LOVE this plane and want to fly this beauty. :wink:

This way you can turn once you got some kts on, 2-3kts works best for me. You can not turn it on a standstill, but hey you can turn.

Thanks alot! Works great, a very clever idea. :slight_smile:

Thanks ! The “phantom rudder” does indeed work very nicely. :+1:

Which place?

Thanks for the tip! I also hope Wookiee and team are OK with it - I know the Goose is not open source per se, but with configs being so easy to tinker with I feel like it’s at the worst a grey area, so long as no one is redistributing the changed version anyway.

It’s probably something we’re going to have to add anyway until MSFS fix differential thrust.

Not gonna lie, a phantom rudder definitely crossed my mind! I think this is definitely a good step forward. :+1:t3::grimacing:

Is this ac free to download?

Yes it is and its fantastic

Hello, nice work nice pic.

but i cannot test it, gdrive link is always busy :frowning:

No. You must transfer $10,000 to my numbered Swiss account before the Google link will work :sunglasses:

Been working on a Checklist or kneeboard for this. I have gleaned most of the basics but there is a lot of detail such as when and in what order the electronics should be turned on, propeller RPM use and other details I can’t find. Is there a flight manual available anywhere for the Goose?

Great aircraft; thanks so much for your work on it. I landed this baby right on the Grand Canal in Venice with no problems – handles better than I expected!

I do have a problem with the engines stalling when at idle, though. For example, if I start active on a runway, the engines will stall out and quit within 20 seconds or so. If I throttle up quickly, no issues. I’m 99% sure this is due to me being an idiot in some way, but I thought I’d report it at least…
