I’m opening that discussion because i’m investigating on the question that regards the motor speed on both prop’s on a same counter rotating “CR” set.
=> The idea behind is to evaluate the benefit of using different pitches on top and bottom propellers.
The bottom propeller receives an air flow with a different speed than the top one obviously, so why should be they be the same !?
I investigated in the log and found that 2 CR prop’s are not receiving the same RCOU, value is a bit lower on one (not necessary upper or lower)
Relatively parallel as this:
But what seems curious to me is the fact that sometime they go in opposite direction:
- What information can autopilot use to decide this ?
=> it does not know the speed of each motor, neither current in each motor …
If someone can give us some information on this ? this would help the investigations
My next try is using 1047 on top and 1055 on bottom, i will try to evaluate if the drone takes less power while hoovering or even increases the max thrust…
