"Can you give me an example where the 2 diagonal motors would need to provide more power.
Weight too far forward = front 2 motors running faster
Weight too far back = back too motors running faster
Weight to left side = left 2 motors running…"
"I could accept that if it was the 2 front motors, or the 2 motors on one side or the 2 back motors, but the fact it is 2 motors on the diagonal makes if very strange.
Also worth noting that the copter balances on both axis on its CG"
I have found an issue with the quad software that needs to be looked at.
I have been mucking around trying to work out why I am not getting full power out of my quad (CF reptile deadcat frame running Sunnysky 2216 900kc on 3S and…"
I will check and see if I captured any of the log files today, normally I turn them off, will report back if I have some before and after the changes, I have a feeling the new quad will have some."
A few pages back I questioned the "I" settings being the same as the "P" settings after auto tune, not having a go at the devs but the reply was more or less that these don't really matter much. I found this odd…"
"Wow really, it use to be about a 2 to 1 figure (I was half your P), has this changed and when?. Guess I will have to play with these some more, might be worth a string test, explains some of the issues at high speed and in the wind I guess as the I…"
"I can't agree with you there, reducing the filtering (if you have very low/no vibrations) does increase the performance, especially in the wind, this is even more evident on large birds (like my 1300mm Octo). Thats kind of like saying turning…"
"maybe change it to something like "land" or "save Trim" or "super simple" mode (all from the PID screen on channel 7) and see if that works. You can also use channel 8 maybe try that one.
Make sure you have no trim or…"
"under initial setup you will find the frame type menu, just select "v" in that menu (you will see it the picture of the deadcat next to it).
Yeah you are definitely going to have to do something about the dampening between the…"
"Autotune is switched to from another switch. So you go into Alt hold on your mode switch, then you assign another 2 position switch (in the PID screen on channel 7 from memory) and while in alt hold you flick the other separate 2 position switch too…"
"did you put the frame in "V" style as needed for the TBS/Deadcat setup?
This will split the roll and pitch ( as well as fix most of the roll movement when yawing). You may also find that it did not finish the roll as it ended up with too…"
Firstly let me just say Auto Tune ROCKS!
Just thought I would mention that auto tune does not like it when you increase the sensor rate above default (20hz).
I have less than 0.02 vibration on my 1300mm Octo and less 0.25…"
"1. Have calibrated and re-calibrated to make sure, no difference.
2. Will do, will have to wait till tomorrow now.
So Thro_Alt_P has no affect on climb rate requests in stable/acro mode?
Also what effect will disabling "Thrust…"
Been using APM for a many years now and finally got around to putting one on a sporty quad (use them on my professional rigs as well as planes). It has all the bells and whistles (over 4kg of thrust from sunnysky motors on 11x5 CF props,…"
"Are you sure its not vibrations, it should not TB if the accelerometers are saying a different story....I could be wrong.
I have a couple of multi's on 3.0.1, 2 of which were flow and tuned without calibrating either the compass or the compass…"
