Speedybee F405 V4 throttle problem

[jitendra01]

I used Speedybee F405 V4 stack for building a fpv drone. After completing the assembly When I am trying to fly my drone, I increase the throttle in my transmitter after increasing throttle to 20% the drone get lifted to 6feet+ height. But it gradually increase altitude without increasing throttle. I have watched multiple videos on YouTube and try to fix the issue. As I am thinking that it is a programming issue and after many trails the problem is not resolved. Can anyone here know about this issue. And can help me to figure out it.

It is not a issue but a feature, FPV drones do not have altitude hold like DJI drones(unless you are using INav and have altitude hold enabled). You need to constantly change your throttle in order to maintain a height or position. This is a key feature that differentiates FPV drones from others!
