The model aircraft I bought from the mall has an engine thrust failure when the aircraft climbs to an altitude of 25,000-5,0000. Small fans appear on the exterior of the model, and the AP automatically disconnects. This has already happened four times. Please fix this promptly.

Hi,

Please attach a short video of the issues you're describing, so I can send to the team for further review.

Thanks!
