"I simply don't understand. Next year for sure, somebody will give us a link to
one another possible autopilot: 256 processors, 128GB RAM, 12GHZ speed. All in one chip.
Theoretically, one super autopilot like this will be able to work with 10 video…"

"@George P. - If you twist all cables (plus with minus,motor cables), lot of EMI will be canceled;however 2-3 deg error will be in compass when motors are spinning but can be removed in software.
@Crispin - Thank you."
At the beginning I made Ap's with even 4 MCU's. All of them ATmega. One was doing R/C reading, another GPS and compass,etc. I did a big step forward when XMEGA came out. With it, I made my first AP with one MCU only. It was possible not…"
"This does not look like P (proportional gain) adjustment to me. What he is adjusting looks like Derivative gain.
Prop=Error*Gain . As long as quad is keep tilted, Error will be proportional to that tilt angle.
So when he turns the quad almost 90…"
My latest autopilot with new ADXRS453 gyros is ready for testing.- Two switching power supplies (Traco Power) at 6.5V and 5V for low power dissipation- Separated reference voltage with RLC filter for sensors- Separated reference voltage with RLC…
"@ Sandro Benigno: the MOS transistors are rated at 100A. However to keep them below 50 deg C and because of the size of copper tracks, I'm not going more than 30A. At 10-15A, the ESC is cold (room temperature)."
I just got 3 pcs. ADXRS453 gyros from Analog Devices ( Farnell price was 100US$ for one piece.) I added also one ADXRS610 in the picture to compare the size of the gyros. As you can see it can be connected vertical for pitch/roll or horizontal for…
