Read more…Hi all,
I'm having a heck of a time getting my ESCs calibrated & motors armed… getting a slow beep every second from 2 of my 6 ESC/motors. I'm building a 3DR Hex kit with 20 amp ESC & 880kv motors.
Here's what I did:
APM 2.5 hardware
APM 2.65 software
Steps:
1) start FG on the ground via Mission Planner.
2) Set plane to Auto
3) I restart FG at same location but at 30,000 ft.
Results: plane does a tight spiral dive to the waypoint altitude, then goes to the waypoint. Ig

I'm programming a quad from scratch (for fun) and have got gyro/accel data and pwm working fine, but I'm strugging on the PID stuff.
I tried tuning a PID with Input = pitch angle, output = motor offset, where:
motor[front].pulse = 1000 + thrott

Can´t find the port on the 2.5 where to connect the speed sonsor. Even not in Wiki, this ends at the 2.0 board.
Am I right to solder pins to UART2 (next to pins of UART0) and connect the sensor there?
many thanks

May I kindly ask for advise.
Documentation of this complex issue is a big job.
Sometimes it drives me nuts, as th the version I have looks completely different than in the docs.
Anyhow, as I think I have blown the uart 3 on my APM1, I
