Hi everyone,
I am encountering several issues with my hexacopter and need guidance on resolving them. Here are the details of my configuration and the problems I’m facing:
Drone Configuration:
Motors: ReadyToSky 920 KV BLDC Motors
Flight Controller: PIXHAWK 2.4.8 (ArduPilot Firmware)
ESCs: ReadyToSky 40A 2-4S ESC
Battery: Tattu 22.2V 6S 25C LiPo
Transmitter/Receiver: FlySky FS-i6 2.4G 6CH PPM with FS-iA6B Receiver
GPS Module: NEO-M8N GPS Module with Compass
Propellers: Orange HD 1045 (10x4.5) Carbon Nylon DJI
Frame: Self-manufactured, carbon fiber (700mm x 700mm x 250mm)
Issues:
- Disabled Pre-Arm Checks:
Gyroscope
Logging
XY/Position control
Z/Altitude control
Battery check
These pre-arm checks are currently disabled, and I am unable to re-enable them.
- Instability During Flight:
The drone is unstable, especially at low altitudes (~40 cm). not taked Flight more then 50 cm altitude
It eventually crashes during landing despite no apparent hardware damage.
- No Logs Available:
Since logging is disabled, I cannot provide flight logs for further analysis.
What I’ve Tried:
-
Recalibrated the gyroscope, accelerometer, and compass.
-
Verified all hardware connections (motors, ESCs, GPS, and battery).
-
Attempted to enable the pre-arm checks through Mission Planner and qground control, but they remain disabled.
Request:
-
How can I enable these pre-arm checks (gyro, logging, xy/position control, z/altitude control, and battery) on a Pixhawk 2.4.8 with ArduPilot firmware?
-
Could the disabled pre-arm checks be causing the instability?
-
Are there alternative diagnostic steps I can take without logs to troubleshoot the instability issue?
