Ok All,

Over the last couple of months I have been going through the process of building my own scale propellers for my FMS 1.4m FW-190 A/8. I've had some success but my first props needed lots of refinement. They were too thick and too heavy in all the wrong places. The master for the first set of blades was carved from balsa wood. I then boxed it into a two part mold from which I could cast the functional blades. I used a rigid two part polyurethane plastic for these blades. It's a good material but as I said, the weight distribution of the blade was all wrong. Too heavy towards the tips and not enough material at the root. Plus the airfoil shape itself was not ideal. (my first attemp, give me a break. At least they flew.....once anyway )

Link to my videos of the Prop tests are below.
