  • Great additions John! And thanks for letting me know about Terry (same for you Steve) i have managed to get these two!

    In regards to the props, Steve you are correct, they both spin in one direction. And Mike i think i know what your getting at, its the 'slipstream' produced by a propeller having an effect on the rudder. The forced air behind a propeller that turns like a corkscrew hits the rudder causing the aircraft to yaw left. This is only an issue on single prop aircraft with the prop in front of the centreline of the aircraft. On a twin prop aircraft, this is not an issue, and hence both piston and turboprop engines always turn in one direction together, be either anticlockwise or clockwise. Therefore the propeller blades position at startup - feather - will be the same for both props, and by the looks of it, the models are correct in terms of propeller position. Here is a video of an F-27 startup with both props turning clockwise from the front:

    And a Dash 8 Q400 turning its props together anticlockwise from the front:

        <DIV>This is what I was trying to identify. If you look closely the blades on No2 engine are pitched opposite to those on No 1 engine. That's what I was calling a left and right pitched prop set up. Not sure if they are variable pitch on the Piper Seminole.</DIV>

          These are 'handed' props IIRC.
          The World War II Lockheed P-38 Lightning and DeHavilland Hornet were the same. These had a left hand and a right hand turning engine/prop. I'm sure there are plenty more.

            • Ok, another day another Aussie arrival! This time the model is an Aeroclassics TAA DC-3 VH-SBA! After a little research of the reg, i found out that i have actually seen and touched the actual 1:1 aircraft!! How? Well simple, VH-SBA is now VH-AES! VH-AES, is a restored TAA DC-3 which does rounds at various Australian airshows! So i am even more happy that i have this model in my collection! (Last image is a photo of VH-SBA/VH-AES i took at Avalon back in 2011.
