Return of the Beaver


Some news after the SU11 release.

The designed model will be based on the first Beaver models : those with the “air intake” under the engine cover.

This addon will integrate :

  • a regular wheels version (finished),
  • a tundra version (finished),
  • a pure float version ( 50% finished and perhaps also an amphibian)
  • a version with skis (15% finished)

This afternoon, I have finish to add all ribbons and fasteners.
The STOL kit is also added tio the model.

One of last screenshot of this afternoon:


it should have a round cargo window instead of 2 "kenmore"windows

I have search a lot of Beaver’s pictures and I have find that Stolairus (DHC-2 Beaver Products) or Sealand Aviation (The ALASKA DOOR - for the DHC-2 deHavilland Beaver | Sealand Aviation Ltd., Campbell River aircraft manufacturing, maintenance, repairs, modifications) make cargo door modifications on several models of Beaver, non only for the round cargo window. Theses cargo door can have two rectangular windows no equal in size: the first one is smaller to permit to create a solid border betwwen this door and the basic rear door.

Sometimes the images found focus on the cargo hold and you can’t see the whole plane.

you are talking about the modifications. What I meant was a fuselage round window just like the first beavers have. Two square windows at the beginning were modifications as well, as all factory-produced beavers have round ones.

OK, now I understand better.
The biggest work of the project will be in writing and managing the Reality Expension Pack:

  • Engine Wear Management,
  • the management of the weight of the plane (via the onboard elements),
    Moreover, working alone I could not offer several models with several panels. So I will focus on a single plane but with several options for the wheels and floats.
    According to what I exchanged with friends in Quebec, there are Beavers that use floats and then at the change of season change these floats for wheels.


A developer who doesn’t put his work forward is a bad salesman for the team he works for.
So I tried to “roll up my sleeves” (sorry if this french expression) and do what is not in my “comfort zone”: a presentation with video.

I don’t know if you’ll like it, but I had a lot of fun doing it and it allowed me to discover a lot of things, especially in “free” music.
Here is a small composition, to highlight the engine which is the soul of this plane and on which I worked a lot for the Canso (14 cylinders - twin-row engine) but also in this 9 cylinders version for the Beaver. This allows everyone to see all the details, the elements that must be assembled to achieve a “flyable” aircraft but also aesthetic and as faithful as possible to the real aircraft.

Not everything is representable but the devil is in the details …


What engine 3D model you have used? It’s looks more like a DHC-3 Otter engine. :sunglasses:

Engine that I have modelized for my Canso are Pratt & Whitney R-1830 Twin Wasp equiped with 14 cylinders (twin-row design) which displaced 1,830 in3 .

On Beaver, De Havilland has used Pratt & Whitney Wasp Junior R-985 with 9 cylinders. These engines have a displacement of 985 in3.

DC3 Otter has used two kind of engine, if I remember:

  • Pratt & Whitney R-1340 Wasp with 9 cylinders (1,344 in3)
  • ASZ-621R produced by PZL-Kalisz for Polish Otter (9 cylinders - 746 Kw)

For this last engine, read this: De Havilland Canada DHC-3 Otter - utility aircraft

PS: The Shvetsov M-25 was an radial engine produced in the Russia, it was a licensed production variant of the Wright R-1820-F3 Cyclone and ASZ-621R is a variant always produced by Polish enterprise PZL-Kalisz.

I am not interested in the turbo versions, for more informations, you can also read Wikipedia :sunglasses:

I know WASP Junior - I have textured one in the past for X-Plane for Soulmade Simulation DHC-2 Beaver



for what it’s worth - the Wasp Jr was maybe the most widely used radial engine in the US from the time it was first produced. I would happily purchase ANY aircraft built for MSFS that had this engine as it’s factory or retrofitted powerplant…especially if it were as well executed as the one pictured above this comment…I would happily fork over whatever it takes to get a Stearman Ag Duster with exactly that engine hanging off the front end.

Back on topic - Nice Work Mr Lagaffe on your DH2-C

Hello Franck,

I was intrigued by your images and I looked in detail that you have sent. You can notice on these pictures that the ring that distributes the ignition to the spark plugs is behind the rocker arm rods plane. But on the engine I modeled, it’s the opposite !

While looking in my bank of modeled elements (in 2015 after a big intervention on my heart, I decided to learn Blender and I had to model 4 or 5 star engines) I realized that I had made a big mistake, I inserted in the project the Hornet R-1690 model instead of the Wasp R-985.
They look very similar and it’s only this detail on the distribution ramp that allows to differentiate them.
My apologies to Franck who was right.

The advantage of the Hornet is that it offers more than 525 cv instead of the 450 of the Wasp if I am not mistaken :innocent:


For historical reference, the Hornet engine was used in the Lockheed Vega Air Express - Gilmore Special - as flown by Roscoe Turner.

I’m always happy to help in terms of DHC-2 Beaver in any kind :smiley:

Well, after one hour under Blender I have changed the two engines in the Beaver.
The longest operation was to look for an identification plate of the engine but not finding what I was looking for, I finally opted for “a little shot of Gimp” and hop, “the engine is now nickel” !


For textures, I’m used to work with ArmorPaint but I recently bought a new plugin for Blender, we’ll see what it gives: it’s PBR Painter for Blender.

After dinner, the correct R-985 engine was positioned to replace the old one that was not compliant.

You can notice the front part smaller and the ignition ramp which is behind the rocker rods.
The identification plate has also been replaced by the correct :sunglasses:

All is correct / engine, now :wink: Just PBR texturing is needed to complete this part.


That looks SO good

now we’re talking :smiley:

Some news and screens for this week:

Decals and aviation handle for the cargo doors are positionned

As it is an aircraft for bush (hunting/fishing parties), I have include a winchester and some goodies like theses:

A hunting trophy and plastic boxes are provided to keep the interior clean :sunglasses:

All theses elements will be managed as PAX to impact the aircraft total weight .
