My stingray weights about 2.8 kg originally, and it hovers at roughly 80% throttle.
Previously I had built one about the same weight and it hovered just fine, at around 50% percent throttle.
I reduced the weight by changing the battery and now it weighs 2.5Kg but still hovers around the same PWM value.
Any ideas as to what params to look at in order to fix this hovering issue?
I lose yaw authority and overall controllability.
Using orange cube + and 4.5.7 Arduplane.
Plotted is my PWM output and MOTB values for throttle. which all follow each other.
Steps already taken:
calibrated sticks both on Arduplane and controller (FrSky Taurus 10XS)
Reduced weight between hover flights
ESC are calibrated aircraft is properly W&B (confirmed with quad motor outputs as they are close values)
What components and take-off weight? It’s easy enough to determine what it should do for hover throttle.
A link to a .bin flight log is a lot more valuable than posted graphs.
@dkemxr I know it has been a while but I found the issue. I totally agree I will post logs next time.
The main issue was that my motors came with software that I was loading incorrectly, so the issue was not on arduplane but on the motor software.
More precisely the parameter value for my max velocity had change per the manufacturer from 649 rad/s to 1040 rad/sec therefore limiting the maximum speed it was able to reach.
Steps I followed for testing in case any one is interested…
First off ensured my drone frame was good mechanically
did a calibration of stick on controller and on arduplane as well on the stick calibration tab of the set up window
Upside down prop test and then analyzed log for my RC channel corresponding to throttle stick input and then compared to pwm output. This is were I was able to verify i was indeed having missing power.
