Gear fully down from the top as if looking into the engine nacelle. |

The landing gear is another engineering challenge. I was able to find an original drawing of the landing gear configuration, which was really helpful. I didn’t understand how the supporting struts worked until I found it. So I spend several evening trying to create the struts using brass and copper tubing, but realized I could 3D print them with enough detail and strength to work. I had already cut the gear doors out of one of the nacelles and was able to use that as a rig. After getting everything working, I created a test rig out of bamboo skewers for to build the other side. Here is the gear in fully down position. |

| The software does the shading. This is in model mode so the shading is default so you can see the 3D. The tool also allows you to set up cameras and lights so you can render an image however you want. It's pretty extensive. I'm using the defaults here. |

| That's real cool. Does the computer do its own shading? |

Have also worked on 3D modeling the wheels and tires for the Whirlwind. I think these would work for a Mosquito too. They look very similar. This was done in blender and I will use my SLA Printer to print them as two halves. |

Work is slow on the Whirlwind. I’ve been doing more 3D modeling to develop the ends of the engine nacelles. They are attached to the flaps and drop down with them, so I had to modify the model by added a new former to each nacelle and removing the ends. Now the plastic nacelle ends will meet right up with the rest of the nacelle when the flaps are close. I’m also working on infilling. This is by far the most tedious part of modeling! I love the finish, but really had the infill part. And, with such a big model and a fuse with two engine nacelles, there is a lot of infill! I’m going to need to build a WW1 model next just so I can get a break from infill! |

| This build is really interesting. |

Bottom view with flaps open. Note that the Whirlwind had flaps that went all the way across the wing and fuse, so there is a section on the fuse that drops too. |

Bottom view with Flaps closed. |

Top view with Flaps extended |

Working on the wing. Top view. White strips wings are the tracks for the Fowler Flaps. Center cavity formed to the same shape as the fuse for the cockpit. |

Halfway open. |

From the side with flap closed. |

Flap fully open |

Put together a flap test bed to see how my design would work. Took several tries to get a working example. The following are pictures of the last prototype. |

| Thanks! It's nice to build something "regular". My last few models had all those concave shapes. Straight edges and traditional construction is a nice change of pace. |
