Brake in Position Hold

Centre the sticks in Position Hold while the craft is still moving. Brake from above is the speed that starts the stop. The demo uses 1.00 m/s. Slower than that, centring the sticks does not start this brake.

Release brake below is the speed that ends it. The demo uses 0.75 m/s. A speed between those two does not start a new brake, and it does not cancel one that has already started. Drop under 0.75 m/s and the brake lets go.

Brake for at most is the other way it lets go. The demo is 2000 ms. The field runs from 100 to 5000 ms, in steps of 50. When the time is up, the footer’s line applies: it hands back to normal position control, even if the craft is still above the release speed.

The speeds are stored as hundredths of a metre per second. 1.00 m/s is 100 in the setting, and 10.00 m/s is the top of the 0 to 1000 range. The step on screen is 0.05 m/s.

Boost strength is extra stopping force at high speed. The hint says 0 means off. The demo starts at 100%, and the field runs from 0 to 200%. While it is 0, the three boost rows are hidden. Put it back above 0 and they return.

Boost from above defaults to 1.50 m/s. That field will not go below 1.00 m/s, and it tops out at 10.00 m/s, in steps of 0.05. Stop boosting below defaults to 1.00 m/s, and that one can go down to 0. Boost for at most defaults to 750 ms, from 0 to 5000 ms, in steps of 50.

Braking bank angle is how far the craft may lean while this stop is on. It is 15 to 60 degrees, step 1, and the demo starts at 40. The bank limit on the Navigation multirotor card is a different setting, 15 to 45 degrees. Do not copy one into the other and expect the same number.

The Navigation card also has a stopping time. Its hint says the stop point is speed times that time after the sticks centre, and that braking mode overrides it. This page is that braking mode. The stopping time is the softer number. These thresholds are the hard stop.

The same card sets Throttle centre in Alt Hold. The hint says it is where throttle holds altitude: the stick when switched on, mid stick, or hover throttle. The demo starts on the stick at the moment Alt Hold is switched on.

Hover throttle itself is on the Navigation tab, 1000 to 2000 microseconds. Choosing Hover throttle here uses that number. Choosing mid stick holds altitude at the middle of the stick. Choosing the stick at the switch keeps the throttle where it was.

The card is drawn for a multirotor, a tricopter or a helicopter, and only when the board has the altitude-hold throttle setting or the braking speed. A plane, boat, rover or other platform hides it. If the firmware has no platform list, the card is shown.

Chrome or Edge connects over USB or Bluetooth. Android adds Wi-Fi. iPhone uses Bluetooth or Wi-Fi and has no USB host. Try the brake with the props off, the same as any motor test, until you know which way the craft stops.
