RE: Motor issues when running ESC calibration
@Alex-Kushleyev after uploading the new params you sent the ESC no longer communicates with the VOXL2.
The ESC board is no longer recognized by VOXL2. All hardware is set up properly.

Please point us in the right direction.

RE: Motor issues when running ESC calibration
@Alex-Kushleyev Thanks Alex, We will test it out. In the meantime my team will be sending the first FPV 4n1 ESC back, so you can investigate onsite.
Thank you,

RE: Motor issues when running ESC calibration
@Alex-Kushleyev I agree, what do you think the next troubleshooting step is for this issue?

RE: Motor issues when running ESC calibration
From the GCS, executed "take-off" command in "Position Mode" with props off. Motors smoothly increase. I "hand-flew" it up to 1m and UAV was adjusting for small movements correctly.
Executed "Land" and "hand-flew" it to the deck, landing detected and disarmed.

RE: Motor issues when running ESC calibration
Throttle input is being "ignored" regardless of RC Channel input, same response (slow ramp up) when armed in any flight mode (Manual/Stab/Pos etc..) and throttle is increased, even when RC Channel is changed (1,2,3,4).
Motors respond correctly with pitch, yaw, and roll inputs.
PX4 FPV_RevBv4 params are uploaded, switched to 4S and put min/max RPM to 3000/40000.

@Alex-Kushleyev No actionable response from throttle.

RE: Motor issues when running ESC calibration
We kept the custom ESC config for the 2203.5, and uploaded px4 FPV_RevB_v4.
Motors are more responsive in all channels, Throttle channel still conducts a "ramp up", but more aggresively when RC Tx input is applied.

Also, sinusodial value is 0 in FBV_RevB, I will change this to 1.

RE: Motor issues when running ESC calibration
What effect does the aO,a1, and a2 (pwm_vs_rpm curve) have on overall throttle response for FPV 4n1 ESC? in the FPV_RevB the a0 value is -161.0826?
