    This is my 7-inch version of TBS Source One quadcopter frame. So far, so good, Source One is really tough and stiff frame so all the problems with resonance and oscillations in flight should be over. And looks like they are over. It might sound like a good old V8 engine but flies smooth. And…

  • How much does a propeller weight? Mass vs. moment of inertia

    How often, when you watched or read a brushless motor review you’ve heard a sentence like “this motor will not have any problem spinning a heavy propeller” or “this motor is designed for light propellers”. Or “this is a very light propeller”. But what does that really mean? Thanks to our good friend Sir Isaac…

  • Mamba F405 and F40 40A 3-6S 4-in-1 ESC combo hands on
