Hi all
I have a an X8 frame where arms can be replaced and become an X4.
X8 motor configuration has been done following ardupilot tutorials therefore the correct motor sequence become A-C-E-G for the upper motors and B-D-F-H for the bottom motors (as described here http://copter.ardupilot.com/wiki/connecting-the-escs-and-motors/)
Now, I installed the X4 firmware , I would have expected the correct sequence of the motors. so clockwise A-B-C-D, instead C and D are switched.
what would be the best configuration ? I would like to avoid to unplug motor PWM cable to correct motor sequence, so what would be the consequence of using the X8 configuration with just 4 motors?
…obviusly autotune must be redone
thk
this may not be the best solution, but it works for my purposes.
When I have to switch from X8 to X4 config I simply reload the paramenters and that’s all. You don’t need to change the firmware from quad x to x8.
Off course you need to fine tuning your quad x4 running the x8 firmware, but once done you will be fine
Can you point out where i can find info on this. What i am worried is the PID. I am sacred to crash the drone. Do you think the PID will remain the same.
No, the PID will not remain the same. You need to do this to be on the safe side. Google is your friend. Parameter files are simple text files that can be edited with any text editor.
Isnt this the one for a single motor and this is kept as it is from intial tune and has not been changed for the X4. It is also wired to change that cause, since in the wiki it says: Do a bench test and find out. Well my idea was if it flies for the x4 from start and not needed to change why should we change that for the X8
These are also the same from intial tune to the final work. Nothing is changed and why do we need to change cause in the wiki it only talks about the propeller size not the single or coaxial.
What do you think? Cause i am not able find anything although i am trying to google these things.
