1:1 Avro-Roe IV Triplane 1911

Those magnificent men in their flying machines...

The Wiki:

The Roe IV Triplane was an early British aircraft designed by Alliott Verdon Roe and built by A.V. Roe and Company. It was first flown in September 1910. The Roe IV Triplane resembled Roe's Type III, being a tractor configuration triplane with the lower wing of smaller span than the upper two and a triangular section wire-braced fuselage, which was uncovered behind the pilot's seat. The middle wing was mounted directly above the upper longerons, and there was a gap between the single lower longeron and the lower wing. The wings were connected by four unequally-spaced pairs of interplane struts on either side, the innermost pair on each side being just outboard of the upper longerons and the outer pair connecting only the upper pair of wings due to the shorter span of the lower wing. Although the ailerons fitted to the previous design had been satisfactory, Roe returned to wing warping for lateral control. The lifting triplane tailplanes of the earlier design were replaced by a non-lifting single triangular tailplane with a divided elevator and a small unbalanced rudder. The undercarriage consisted of a pair of skids extending forward of the propeller, with a pair of wheels mounted on each skid, and a sprung tailskid. It was powered by a 35 horsepower (26 kW) Green water-cooled four-cylinder inline engine, with the radiator mounted above the fuselage between the front inner interplane struts.

Controls and Features:

-Standard SP Flight Controls

Features:

Custom Everything!! This is my most accurate replica to date. The measurements are exactly as they should. Length, wingspan, and height all match blueprints. The weight is correct to the pound. The engine power is 35hp matching the original and its top speed is a realistic 25mph.

To Fly:

-Throttle up. Tail will lift @ 13mph. Pull up when speed reaches a blistering 22mph. Ta-da!!

As Always:

I am super excited with how this plane turned out. It has been on my to do list for a while, and the result couldn't be better. As previously stated, it is my most accurate replica, and I hope you can appreciate it. As always, please let me know if you have any suggestions for improvement or if there is a vehicle you would like to see recreated. Thank you so much for stopping by to look, and enjoy your flight!!

    Huh, I knew it was slow but not that slow. Thanks for verifying it. @Sgtk

    @ThePrototype Yes, the speed is accurate. The real ones top speed was 25mph. The take off distance was shorter, but the SP engines have a struggle at such low powers and I'm not sure i could reproduce it while maintaining the top speed.

    Is the speed accurate? It seems a little too slow...

    This is really cool, but I must ask.
    How did you make the engine power 35 HP?

    @Sgtk No problemo. Its a fun build and very nice to fly.
    And since you ask for tips on improvement I shall share a few small constructive criticisms of your rather lovely plane that you can easily ignore as they don't really matter to the average joe.

    The radiator is missing (the original aircraft had a radiator between the fuel tank and the engine)

    The fuselage is slightly too shallow but that doesn't really matter.

    The rear fuselage should have a constant taper to the tail rather than being straight and then tapering.

    The rigging wires are too thick for the scale (imo)

    And a custom engine would have looked great on this plane.

    The steering wheel would be relatively easy to animate using scaled down rotators.

    It is missing a few small details such as the sprung tail skid and several rigging wires on the undercarriage and the wires connecting the bottom wing to the middle wing.

    Still I will rate it a 10/10 because I tend to focus on silly insignificant details that nobody else notices because I am a sperg.

    So,I flew the Wright Flyer “simulator” at the Udar-Hazy annex of the Smithsonian, and it could either turn or fly level...but not both! This is exactly how your build feels and should be appreciated for capturing and informing the SP community just how hard it was to fly those early machines, great work!
