What does MSP mean in Betaflight?

MSP is the main communication protocol

communication protocol

A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. The protocol defines the rules, syntax, semantics and synchronization of communication and possible error recovery methods.

Communication protocol - Wikipedia

used by all Betaflight derived flight stacks. It's a binary message based protocol used for control, telemetry and sensors. ArduPilot's MSP protocol module is ported from Betaflight and iNav, and supports both MSPV1 and MSPV2.

What is MSP in iNav?

MSP is the remote messaging protocol used by iNav and other flight controllers such as MultiWii, CleanFlight and BetaFlight. MSPV2 was introduced in iNav 1.73 for legacy commands, and is fully implemented (16bit commands) after 1.73 (i.e. 1.74 development branch and successors).

How do you arm a drone?

What does anti gravity do in Betaflight?

Anti-Gravity is not a flight mode, but a feature. It reduces the “dips” (sudden pitch-down) when you changing throttle rapidly. To do that it basically raises I gain momentarily when throttle is changing a lot, and so I gain will stay the same for the rest of the flight.

What is paralyze mode in Betaflight?

Betaflight 3.5 introduced a new mode called paralyze which disables arming. It can only be invoked while the quad isn't armed. Paralyze is a sticky mode, so once it's active, the FC has to be power cycled.

How do you set throttle in Betaflight?

How do I do it? Easy. First, choose the rate profile you'd like to limit throttle on, up to 6 are available in betaflight now but I only use 3 since I map to a 3 way switch on my transmitter. In the example below I have my 'race rates' on profile 1 and 2 which are identical and use profile 2 for limiting throttle.

How do you disarm APM?

Disarming the motors

Hold throttle at minimum and rudder to the left for 2 seconds. The LED will start flashing indicating the vehicle is disarmed. If using a autopilot with a safety switch, press it until the LED begins flashing.

What is arming and disarming?

The difference between Armed and Disarmed is that various intrusion zones can trigger an alarm while the system is in an Armed state, but not in a Disarmed state. Only 24-Hour Zones are capable of triggering an alarm on a Disarmed security system. A 24-Hour Zone is always active.

What is arming a drone?

In a drone mission, arming involves controlling drone motors and plays a critical part in its flight. Unauthorized arming is a major security challenge associated with drones.

What is APM flight controller?

The APM 2.8 Multicopter Flight Controller is a complete open source autopilot system. This is the best-selling technology that won the prestigious Outback Challenge UAV competition. It allows the user to turn any fixed, rotary-wing.

How do I turn off pre-arm check?

Disabling the Pre-arm Safety Check

Arming checks can be individually disabled by setting the ARMING_CHECK parameter to something other than 1. Setting to 0 completely removes all pre-arm checks. For example, setting to 4 only checks that the GPS has lock.

What is D Max in Betaflight?

The intent of the feature is to allow you to run higher “D_max” values for help during sharp movements, while keeping D gains closer to “D_min” while cruising in order to keep your motors cooler when you don't need the extra D gains.

What is super rate in Betaflight?

The combination of RC Rate and Super Rate determines “max angular velocity” – how fast the drone is allowed to rotate (measured in degrees per second). Expo changes the sensitivity in centre stick. Note that while Super Rate changes max velocity, it also has an effect on centre stick sensitivity too just like Expo.

What is Pit mode?

PIT mode. PIT mode allows a pilot to use their VTX around other pilots during races or on the bench as it minimises the output of the VTX to the lowest possible setting causing the least amount of interference possible. The Pitmode function comes with two features to reduce the user's output frequency.

What is Headfree in Betaflight?

Headfree. In this mode, the "head" of the multicopter is always pointing to the same direction as when the feature was activated. This means that when the multicopter rotates around the Z axis (yaw), the controls will always respond according the same "head" direction.

What is Headadj?

Head Free - When enabled yaw has no effect on pitch/roll inputs. 7. HEADADJ. Heading Adjust - Sets a new yaw origin for HEADFREE mode.

What is FPV Angle mix in Betaflight?

For anyone that doesn't know, FPV Angle Mix changes the controls so that roll and yaw are relative to the camera, instead of to the flight controller. If you're a beginner with a 10 degree camera angle, you won't notice any difference.

Is air mode acro mode?

If you just had acro mode enabled (by default in most flight controllers) whenever your throttle stick is at zero, manoeuvring the drone while it is in the air is harder than being in air mode. Air mode still keeps the PIDs looping even when the throttle stick is at zero (find out about PIDs here).

What is ACRO trainer mode in Betaflight?

Betaflight firmware has ACRO TRAINER mode, which is convenient for Angle mode users to practice Acro mode. If you enable this and fly in Acro mode, roll and pitch angles will be limited, so you can prevent accidental attitude.
