Stiffer frames fly better! This is relatively well known in the community and one of the reasons why box-frames fly so good. The drawback with the box-frame design is that they are weak in in yaw between motor and center-plates. The MAD-S design is our attempt to solve this issue and make a frame that is more balanced in term of stiffness in all directions. Did we achieve this? Well, you be the judge! Down below you can find the results from the measurements. To give you references most drone racers are familiar with, we have and will continue testing the most popular frames on the market and publish the result here for your comparison.
