Re: More powerful coreless motor

It worked! Kind of, it doesn't disconnect anymore which is huge progress but there is still up to a second of delay between controller input and rpm change. The delay gets bigger the longer the crazyflie has been running/how fast . Ill test further tomorrow! Thanks a lot for your help so far!

Re: More powerful coreless motor

Well bad news, i tried what you suggested. I added 4x220uf capacitors in parallel between the battery connector wires and another set of 4x220uf capacitors between vcc and dgnd but i keep having the same issues as before. Cuts off at about 50%

More powerful coreless motor
