Good throttle control starts with watching vertical movement, not searching for one magic stick position. A manual FPV aircraft needs enough upward thrust to balance its weight, and that balance changes as you bank, accelerate or use the battery. Half stick is not a universal hover command.

In Drone Horizon, Standard manual flight and FPV/Acro use collective control. The separate DJI-style stabilized flight family manages height differently. Choose the manual family for the exercises below; otherwise an altitude controller may hide the skill you are trying to practice.

Establish a usable range first

Before flying, inspect the throttle channel from its lowest position to its highest. It should cover the expected range continuously, without jumping from zero to full power. A reversed channel, missed calibration endpoint or throttle bound to a button can make ordinary takeoffs look like a physics problem.

A spring-centered gamepad deserves special attention: releasing the stick returns to its mechanical center, not necessarily to minimum thrust. A radio throttle may remain where you put it. Drone Horizon's normal manual touchscreen throttle also retains its position. Learn your device's release behavior while disarmed.

Exercise 1: climb, settle, descend

Use an open area and a fixed aircraft. Start upright, set minimum throttle and arm. Increase collective gradually until the aircraft leaves the ground. Allow a modest climb, then reduce slightly before reaching your chosen practice height. Watch whether the ground is still moving away; reaching the desired height does not mean the climb has stopped.

Hold a small visual altitude band, then descend deliberately. Arrest the descent above the landing surface before trying to touch down. Repeat until you can distinguish three states: moving upward, nearly level and moving downward. Record how often you need a large corrective input. The goal is fewer abrupt corrections, not a specific percentage on the throttle bar.

Exercise 2: keep height through a wide turn

Fly a broad, shallow turn at a repeatable entry speed. Banking redirects some thrust sideways, so unchanged collective may allow height to fall. Add a small amount as the bank develops, then ease it out as you level. Making the throttle change after a large drop means you must recover both height and downward momentum.

What you see Likely practice adjustment
Climb begins after every correction Make smaller changes and allow time to observe them
Height falls mainly in corners Coordinate throttle with the developing bank
Aircraft launches when a gamepad is released Check spring-centering and the throttle mapping
Only the top half of travel changes thrust Recheck endpoints and whether a trigger-style mapping was selected

Why hover drifts during a session

Different simulated aircraft have different mass, thrust and battery characteristics. Drone Horizon includes battery-dependent motor output, so the same stick position need not produce identical lift throughout a session. Resetting between comparisons and keeping the aircraft constant makes early practice easier to interpret.

Throttle expo can spread useful control around a region of the stick, but it cannot turn manual collective into altitude hold. Fix calibration before tuning the curve. See expo explained when basic movement is already predictable.

A useful finish criterion

Finish this drill when you can make several calm climbs and descents, maintain roughly the same height through both left and right turns, and land without a final throttle jab. Then combine it with pitch and roll coordination. All suggested heights and repetitions are simulator exercises, not clearance rules for real-world flying.
