I’m building a quadcopter from scratch following the UDEMY course. I have it built but when I tried a test flight, it flipped on its side. I’ve been through the calibrations many times. I’m trying to understand what may be the problem besides replacing the cheap ESCs and motors. I’m using a MATEK F405-TE controller. I’m struggling understanding the huge amount of data in the log but this caught my eye, but I have no idea what to do with it.
The bin file is huge and I can’t upload it. So, I could also use some suggesting on what to log and what not to log for future flights.
Thanks for the quick reply. That was my first, second and third concern. Obviously I am missing something. Where I test the motors, the appear to be correct and turning in the right direction. What am I missing?
ABCD = 2134 on the Flight Controller = 1423 on the X-copotr labeling as I map it out using the documentation in Mission Planner. As I said earlier, when I test the motors, the are rotating in the right direction and I have the propellers providing lift, just not evenly. Anyone else with ideas?
OK, here is an image directly from Mission Planer. A=1, B=4, C=2 and D=3. That would be great if the MATEK T405-TE FC was numbered the same way, which is 2,1,3,4. I took you advise and oriented all up. (I rotated the MP image to match then MATEK documentation) So, by my understanding,
Matek Board Position 2 = Frame Position 1 = Mission Planner A
Matek Board Position 1 = Frame Position 4 = Mission Planner B
Matek Board Position 3 = Frame Position 2 = Mission Planner C
Matek Board Position 4 = Frame Position 3 = Mission Planner D
Simple logic.
Run Motor Test and note which motors run when you select the A thru D buttons. If they are incorrect as per the FRAME_TYPE you have set, and the illustration, re-factor the SERVOx_FUNCTION parameters until they are in the right order. And then of course make sure they also run in the correct direction.
That’s it.
Thanks for your reply. I had motors turning in the right direction and, using Test Motors, the correct motors were responding as per the frame diagram. All corners of the copter were running with lift, but the drone kept flipping on its side. I am now in the process of replacing the motors and cheap yellow ESCs and wiring to a power distribution plate. Any other suggestions are most welcome.
Replacing Motors and or ESCs sounds like just try and error method which is in my eyes is an expencive method.
Better is first to analyse the problem correct.
So did you tried to use @amilcarlucas methodic configurator SW first? This is for free only uses some of your time.
If this not help present your param and log files.
I agree that replacing components is not the best approach, but I am at a loss to diagnose the issue further than I have. I had no idea that the Methodic Configurator was available. Wow, what a resource!! That is incredible. I looked at “hardware to avoid” and my quadcopter build uses most of those mentioned. I’m just shaking my head, I installed new ESCs and motors and triple checked rotation using Test Motors and also when armed and attempting to fly, but the copter still flips on its side. Is there a way to use the Methodic Configurator using the FG450 frame and the unrecommended ESCs and motors? I just want to get the copter in the air.
The motor order must be wrong if it flips.
Please describe your testing process in MissionPlanner motor test → what motor operates when you test motor A , and so on…
Draw a picture if you’ve got to.
Or do a video of test in A, B, C, D order so we can see which motors spin.
