RE: Which Wall power supply for Starling 2 Max ?
Hi @souksakone
We do not support powering and arming any sUAS from a power supply. The ESC and other electronics will be damaged, and our warranty does not cover that.If you need a bench top supply for code config, development, etc (without arming motors at all), then we sell a 30W adapter for XT60 here and you can adapt to Starling 2 max without much trouble: https://www.modalai.com/collections/accessories/products/ps-xt60

RE: PWM ESC calibration for VOXL ESC 4-in-1 Mini and QGroundControl
Hi @Martin-Lukac
Good catch on the pin swap. The Table is correct, with Pin 6 = GND.The one thing I was wondering is related to this comment:
" I can power the ESC and the FCv2 separately."
That is not necessarily a good thing, and likely to lead to problems if you are powered up or down at different times. If one output (TX) is driving an unpowered input (RX), it could put the HW in a bad state. Please make sure to have them synced for ON and OFF.
Thanks. -
RE: Urgent Support needed for Drone not armed after RC controller calibration
@oiler251 You should be able to arm with the arm gesture (e.g. moving the left stick to bottom right). But since that isn't working I suggested to configure an arm switch. I do see that the RC2_TRIM parameter is set to 1000.0 which is odd. Normally it is around 1500.00. When you look at the QGC radio configuration screen and you move the sticks around do they look normal? And when sticks are centered are they all showing that they centered on the graphics? You could try setting RC2_TRIM to 1500.0 and see if that allows you to arm with the gesture. Please make sure you have the propellers removed when doing this testing!

@oiler251 The PX4 User Manual has some documentation here: https://docs.px4.io/main/en/advanced_config/prearm_arm_disarm. QGroundControl User Manual has some documentation here: https://docs.qgroundcontrol.com/master/en/qgc-user-guide/setup_view/flight_modes_px4.html#flight-mode-settings

RE: Urgent Support needed for Drone not armed after RC controller calibration
@oiler251 Please be aware that the Starling 2 Max is a development drone and it is targeted for experienced developers who already are comfortable with using PX4, QGroundControl, Linux, and embedded systems. Drones can be extremely dangerous and should only be setup and flown by personnel with the required knowledge. Safety must be everyone's first priority.

RE: Urgent Support needed for Drone not armed after RC controller calibration
@oiler251 For arming I would configure an arm switch instead of using the arm gesture (moving throttle to bottom right).

RE: Urgent Support needed for Drone not armed after RC controller calibration
@oiler251 It seems like in QGC you cannot just change that value directly, you have to uncheck all of the boxes instead of the satellite count one. Then it will go to 1. Then you can save, reboot and try to arm. I think before doing that, however, you should first try to change EKF2_REQ_HDRIFT to 1.0 as suggested. That is a more precise way to make the adjustment.

RE: Urgent Support needed for Drone not armed after RC controller calibration
@oiler251 Here's what ChatGPT says:
The pre-arm message “GPS Horizontal Position Drift too high” is gated by **EKF2_REQ_HDRIFT**. If you truly need to relax that check, raise **EKF2_REQ_HDRIFT** (default is often ~0.5 m/s). For example, set it closer to **1.0 m/s** so the EKF will accept more horizontal drift while on the ground and allow arming. The related on-ground GPS checks are toggled by the **EKF2_GPS_CHECK** bitmask (bits **5** and **7** cover horizontal drift and horizontal speed, respectively), but changing the threshold via EKF2_REQ_HDRIFT is the usual tweak. ([PX4 Documentation][1]) Quick steps in QGroundControl: Parameters → search “EKF2_REQ_HDRIFT” → increase slightly → write & reboot. ⚠️ Note: loosening this check masks a real reception problem (antenna placement, multipath, EMI). If possible, fix the root cause instead of weakening safety checks.
