Hi guys. This morning I had to reconfigure my F550. I needed the 40a 6S capable esc it had for a future Y6 build.I just swapped them for rctimer 30A 4S opto esc I had from another build. The motors…Continue
"I understand the magnetization but these motors had fly several times just with different esc and I just was not able to make the remaining 5 motors/esc show any kind of problems. Only that single esc.
How tha hell are some YouTube users able to at…"
"I think the issue is magnetization of motor stators. This happens with certain make/brand of motors. There is no ESC sync issue. I spent 3 months last year on this issue. motors with high poles get magnetized generally after 10 mins of flight. then…"
"with 6 motors i heard you are suppose to be able to fly if you lose one...well, mine didnt when one motor failed....it flew for while but eventually hit ground kinda hard, thou not as hard as if it had totally died on all motors....
it depends on…"
Hi guys. This morning I had to reconfigure my F550. I needed the 40a 6S capable esc it had for a future Y6 build.I just swapped them for rctimer 30A 4S opto esc I had from another build. The motors are rctimers hp2217-930kv with 10x3.8 props so all should had been ok running at 4S.Unfortunately, motor number 1 stalled in mid air. For the first seconds it was like nothing had happen. After that initial seconds things happened so fast that I don't remember actually what I did but I do remember…See More
"Didn't Rob explain its supposed to be like that? They are accelerometers after all and I really pushed the hexa to the limits so they are measuring the actual aceleration during maneuvers. The "grass" height is actually very…"
"Here you go.
First couple of minutes it is hovering in the same place. Then you have some really easy flying in poshold and then some really hard poshold flying. You also have some full pitch and full back and also full roll left and full roll…"
"Thank you for explaining. The flight was aggressive and that was the point. To see if I have tamed the vibrations. So to be clear, when looking for vibrations the grass height is what counts and the waves are actual Gs from maneuvers, correct?
"Now that's a relief. I really did push it with full throttle and hard turns. In loiter/mission it will stay bellow 15 and my gopro footage has none to "you really to look for" jello. The start of the graph I posted, confirms bellow 15…"
"Guys... I need some clarification on my vibration levels.
Do I have vibration problems ??? I do not understand if my graphs are dangerous or ok!
If I look only at the "grass" height I'm ok but if I look at -+3 and -+15 range…"
"Tomorrow I have some testing to do. I'm going to connect my voltage divider to pixhawk and a frsky lipo sensor to the battery and see if they match while in flight. If they do I'll just continue using my voltage divider and stop using…"
"I would agree with you if my own voltage divider behaved the same way and it does not. It gives the correct reading without and with load. The only diference I can think of is the point were it measures the battery.
The attopilot voltage divider…"
"God dammit I'm not alone on this. It has to be a bad ground reference or some ground loop while we have load. I already cut the attopilot ground trace so the ground comes from the pixhawk after the bec and attopilot shunt resistor but I still…"
