@steve_L who do you think makes the best (right now) 20x20 stack? just got my armattan 2" frames in.
@MrrGrrGrr I can't answer that as I am not a big fan of the stacks. I've only tried two of the stacks but I can say don't buy the flycolor raptor S-tower, as that still uses MWOSD which is a pain, and the maker imprints "flycolor" on the OSD which cannot be removed via the MWOSD GUI, but that may be not important for everyone.
On a side note, I've starting rotating my micro 4in1 ESCs 180 degrees to allow for easier zip tying for strain relief. The micro ESC battery pads are so close to the rear edge of the frame that zip tying for strain relief is impossible, but rotating the ESC allows the wires to gradually slope down to the frame and allows greater flexibility. The additional length of wire probably adds about 1g. Just have to remember to remap the motor outputs via the Betaflight CLI.
I also used a capacitor board and made a mini-toroid inductor with a M3 plastic washer to create an LC filter for the micro cam.
An inductor can be made by winding wire around anything to make a coil, and the magnetic field created will still resist AC current. Most toroid inductors use ferrite or powdered iron to create a much stronger magnetic field and increase inductance. Since there is no toroid that small, I just wound the coil with a washer. It may not be as effective as a ferrite core but any bit of inductance helps.
I have some. what do you need?
