DO NOT ATTEMPT TO USE THESE BLADES ON A MODEL HELICOPTER!!! These rotor blades are designed exclusively for use with RC model Autogyros. Always observe all safety precautions when operating RC Models and NEVER fly where there could be any danger to persons or animals, including yourself!!!! I designed these blades for use on my Whippet, an excellent design by Rich Harris, links to flying videos are in the thread linked below. These blades should be printed in sets of 2 or 3 with the trailing edges places very close together in your slicer so that all 2 or 3 sections print joined together to prevent poor print quality at the top of the print as shown in the picture. You MUST use a Glass Fibre rod as a spar (dia. 3 mm) and plumbers lead solder can be SECURELY glued into the groove hear the tip if required, USE CAUTION and ensure that the weights are SECURELY glued in. If you are using a GRP plate style rotor head use the angled button (15-0 is recommended) if using a Delta 3 style hinged head use the Rounded Root buttons (0 is recommended). If you have trouble getting the blades to spin-up increase the negative angle of attack using the buttons.
