Mast flex, third post. Another stiffness test, signature mast (75cm long, 14-17mm thick) vs cedrus mast (77cm long, 19mm thick).
A 30 pounds load is applied at the tip of the wing, vertically for bending and horizontally for twisting, and the flex is measured in cm.
Flex : The cedrus mast bends ~20% less and twists the same as the signature mast. At this point the accuracy of the test would have to be increased to quantify the small difference.
Weight : The cedrus (classic) mast with mount and adaptor weights 1.63kg, the signature mast with mount integrated weights 1.88kg, cedrus is 14% lighter and probably stronger.
Drag : To be tested in the water!
Super impressed by the signature mast, and wondering if there is a way to make it universal? 🤔 Custom fuselages could be made for each brand, or maybe just like the cedrus, mast to fuse adaptor. The problem is that the connection area is thin and made out of carbon, it may not be strong enough.
@kdmaui Have you spent some time on a signature mast to confirm its rigidity? How does it compare to a slingshot phantasm?
