I would love some advice with these lines from my log fileTest: Compass = GOOD - No MAG data, unable to test mag_field interference(Loiter seems pretty locked in, so I'm confused about the "no mag…Continue
"I'm using DJI's NDJ6 RC with the Pixhawk 2.1 flight controller in Mission Planner. All I want to do is set one of the three-state digital switches to control the flight mode of my copter, but Mission Planner is reading the analog wheel as…"
"Hey Clifton! Thank you for that idea with connection of receiver channel 6 and board channel 5. I did can not change PWM value on channel 5 to get different flight modes. So after I've read your message I've tried to connect channel 5 on…"
I had the same issue. I was able to change the flight mode channel in the Pixhawk firmware but you have to install the Pixhawk Eclipse development environment and change some of the source code.
Go into Arducopter Parameters.cpp and…"
"I had Maytech ST 30A opto's that would not spin 6 motors. During ESC calibration they worked fine, but in RC mode the motors sounded very sick, probably similar to as described by the OP. I ran some tests, thought I found two (!!) bad ones, got…"
"With opto esc, you have to provide 5 volts on the "servo side" to power the LED of your ESC "opto side " (most of the time)
So insure you have a voltage in between the top row marked "-" and the middle row marked…"
Did you ever resolve this issue? You arent the only one having issues with pixhawk and Spider Opto ESCs on a hexacopter. I have a similar setup to yours and have experienced the EXACT same problems you have described. Have also done all the…"
"I have got half a solution:
In the [AUX-CH] menu set the CH5 setting to "HOV THRO" or "HOV PIT" will allow you to set the Pixhawk flight mode using one of the potentiometers on the top of the transmitter."
The first time you plug the battery in with full throttle engaged, try not using the safety switch. Just plug in the battery, wait for the tunes to clear, and un-plug battery. When you plug the battery back in the second time, wait for a…"
"Do you power your flight controller with the ESC BEC? If yes then a band aid would be to solder a 470uF capacitor on a servo wire and connect it to a free pin on the FC so it can fix a bit of those spikes of power brown outs.
But a fix would be to…"
I'm a motion graphics designer with an interest in photography/videography, and now multi-rotors.
Please tell us a bit about your UAV interest
New to the multi-rotor world, but have always been a huge aviation enthusiast. I've built a 220 size micro quad with the KK board. I spider frame 450 with another KK board. I'm currently building a S550 running a Pixhawk.
