I am new to this community so please help me to solve my problem.
Few months earlier I tried Althold mode with ardupilot and there was no problem everything was working just fine but now there is a problem.
The drone is working perfectly in Stabilize mode but when I go into Althold mode and then ARM and start taking off after some height like 0.2m the drone keeps on moving upwards and becomes uncontrollable. Please find the log file attached
You are using a very old release candidate version of firmware on default parameters. Update to curent Stable version (4.3.4 today). Then proceed to the Initial Parameter Setup page in Mission Planners Mandatory Hardware section and update those parameters based on you craft’s props size and battery power. Then you will be at a base level to start tuning.
