Hi:

I am new to the quad building hobby.  Trying to get my Revolution board working on my S500 frame.

I tried flying the quad after basic config., without sensor calibration and the quad flew like a "drunken" sailor.  I was advised by one of the members of this forum that I should have done the sensor calibration and was amazed that the quad even armed without the sensor calibration.

Attached my GPS to the main port of CC3D at 57600 baud rate, saved and power cycled.  I believe auto-config worked and GPS got recognized.  Please see the attached screenshot.

Below is my GPS

Any assistance is appreciated

If the gps doesn't get a fix and you're testing it outside, replace the gps.

You need to fix your "drunken flying" behaviour, before even attempting more advanced modes, such as autonomous flight modes with GPS. Adding GPS won't fix that magically, you need first to get copter flying well in Complementary (Basic) before attempting anything more advanced.

Thanks very much.  I will contact the vendor to get the replacement.

My copter flew like a "drunken" soldier during its maiden flight.  I raised this question in the forum and a member mentioned that I need to do sensor calibration for a revolution based copter to fly.  Is that correct?  Or should I start a new topic describing this issue?

Below is the thread where I discussed my issue previously

Thanks kindly

You should read about calibration here
https://librepilot.atlassian.net/wiki/display/LPDOC/Sensor+calibration

If you don't do that. Then you flight-controller basically does not "know" to what level to stabilize, where ground is etc...
Every flight-controller needs sensor calibration always, otherwise it won't work correctly.

I think you should not use GPS now, but start with basic flight modes, using Complementary. Once you become familiar with all the options, and what is needed for GPS flight modes, only then step up to use GPS.

All sensor calibration is mostly needed while setup a GPS assisted vehicle to get the best accuracy from the sensors, running INS13.
If you run Complementary, your Revo board should works perfectly at Wizard end with only the level calibration done. Like a CC3D setup.

How is mounted/oriented your Revo board ?

[mak24]

Sorry, what does running complementary mean?  Does this mean not using GPS assisted mode?

My FC is mounted facing forward.  Please see the screenshot.  My receiver is at the front of the copter.

FYI.  I had am APM 2.6 working on this quad (I have dropped APM for now.  One of the forum member convinced me:-))

[f5soh]

Complementary refers to the Basic fusion algorithm used with CC3D, this is the default at wizard end.

Mount looks fine here, sometimes while the board is facing down the level settings are not set correctly.
Maybe you just need to adjust PID for a more locked result.

Please post your config file:
File > Export UAV settings

Hi:

Please find attached my config file

[f5soh]

I see nothing wrong in your config file.

Try adjusting PID, if you have a potentiometer in your radio you can use the last channel input as Accessory for EasyTune.
As a start you can set the Pitch/Roll with same PID.

https://librepilot.atlassian.net/wiki/display/LPDOC/EasyTune

Add some filtering for accelerometers, go to Attitude > filtering

[mak24]

Thanks - Will try changing the PIDs

Please see my APM PID settings for this copter.  Using these settings, the copter had a stable non-GPS assisted flight

I have also attached my CC3D PIDs.

In order to copy my APM PIDs to CC3D PID, do I need to change the settings to as follows using Basic Configuration?:

Proportional:
Roll = 15
Pitch = 15
Yaw = 20

Integral:

Roll = 10
Pitch = 10
Yaw = 2

Please advise

[f5soh]

All those settings are default, no idea about relation between Apm and LP settings.

Try easytune to make your own settings.

[mak24]

Got it.  Will try.

Thanks for all the help

[mak24]

For Easy Tune, does Roll Rate.kp mean Roll rate PID shown in the Easy Tune Video below?



Regards

You should choose EasyTuneRatePitch  and/or EasyTuneRateRoll
