Lathe turning from DXF drawing is intuitive and easy way to make parts of any shape.
Tests of 0603 vs 0802 at high frequency PWM. 0603 shows 60% flight time enhancement and this flight time is 17% more than the best of 0802.
Explanation of higher efficiency with PWM frequency, efficiency vs damping and theoretical limit of efficiency improvement.
JESC efficiency measured for 24kHz, 48kHz damped and undamped versions.
MSP (MultiiWii) protocol exchange between DJI FPV AIR UNIT and BETAFLIGHT MSP port.
Replacement of 2xPH2.0 to single XT30 in 2S whoop often burn voltatge regulator out. Here I consider why it happens and possible methods of prevention by numerical simulation of the circuit
0603 and 0802 motors are compared. The reason of different flight time is a bug in BLHeli_S firmware that affects 0603 motors. The thrust and rpm curves are the same, the only difference is current consumption caused by excess braking.
Proof-of-concept ESC firmware mod makes flight 30% longer. Video tests.
Analysis (experimental and simulation) of the BLDC efficiency. The answer why BLDC-driven copters have low efficiency found!
Based on my recent theoretical model experimental data are analyzed, motor inductance is determined and data are fitted vs PWM frequency
