Rotorflight Release Candidate 3 2.0.0 is ready

NOTE! This is the third public release of Rotorflight-2, suitable for all audiences.​

Notes​

There is a new website www.rotorflight.org for Rotorflight 2. The old Wiki in github is deprecated, and is for Rotorflight-1 only. Rotorflight 2 is NOT backward compatible with RF1. You MUST NOT load your configuration dump from RF1 into RF2. If coming from RF1, please setup your helicopter from scratch for RF2. Follow the instructions on the website! As always, please double check your configuration on the bench before flying!

Support​

The main source of Rotorflight information and instructions is now the Website.

Rotorflight has a strong presence on the Discord platform - you can join us here. Discord is the primary location for support, questions and discussions. The developers are all active there, many pro pilots and several manufacturers of RF Flight Controllers. This is a great place to ask for advice or discuss any complicated problems or even new ideas.

There is also a Rotorflight Facebook Group for hanging out with other Rotorflight pilots.

Changes from 2.0.0-RC2​

There are very few changes, though we decided to add one larger improvement that is improving stability in hover. It should not affect flight performance otherwise.

From now on, only super critical fixes are accepted, plus the missing language translations!

The Release is expected in a week or two.

EVERYBODY please test the Release Candidates best to your capabilities. Your help is appreciated.

Changes to the Firmware:​

• Improved stability in hover
• Extended throttle PWM pulse limits to allow narrow band servos
• Extended governor max throttle range to 0..100%
• Fixed governor passthrough throttle ramp-down in IDLE

A few notes about the 20240218 snapshot​

CRSF Reuse​

EdgeTx 2.9.3 broke the CRSF sensor reuse by changing the sensor scaling. The CRSF reuse has now been refactored for better support for different EdgeTx versions.

There are now more sensors that can be reused. The reusable sensors in the GPS frame are altitude, heading, ground speed, and satellite count.

The reuse options are now selected based on the original sensor scaling, so that the reused value can be expressed correctly.

For most reuse options, the "ratio" in EdgeTx is a variation of 255. E.g. 25.5, 255, 2550, 25500. (including RPM!)

The voltage sensors use 20 or 200.

OpenYGE ESC Telemetry​

There is now telemetry support for YGE ESCs (thanks Bob!). This is a brand new protocol implemented by YGE especially for Rotorflight. It will be available in the next ESC firmware update from YGE.

Default values in the Firmware​

Many defaults have been improved. Please note that you won't get any new defaults if you load a dump all from the previous snapshot. Probably better to use a diff all, which will apply only the parameter values that are not on default values.

Next one will be a Release Candidate, so please report any issues promptly!

Happy tuning (and maybe even flying)!

Changes from 2.0.0-20240105

• Fix tail trim rounding
• Fix yaw direction in Rates tab
• Refactor config handling in Power tab
• Show Charge level in Power tab
• Show Realtime Load on the bottom bar
• Add Yaw precomp (lowpass filter) cutoff
• Move RPM Sensor switch to Motors tab

• Update zh_CN locale
• Add TTA Debug mode
• Add CMS feature flag
• Add Setpoint Response time and acceleration on Rates tab

A few notes about the 20240128 snapshot​

New ARMING disable flags​

Arming is now disabled if there is no fast RPM signal available, and the governor or/and RPM filter is enabled. Also, the governor mode 2 requires battery voltage. Arming is disabled if it is not available.

Realtime Load​

There is a new Load figure on the bottom bar in the Configurator. It is showing the peak "real-time load" in the FC. The realtime load is the percentage of CPU time used in real-time tasks after every gyro sample. It must stay below 70% or so for the FC to work at all.

Blackbox logging is the single most CPU intensive task in the FC.​

Once enabled, it can easily double the load. Please check that the FC stays below 70% with logging enabled!

CRSF Voltage telemetry​

There are new options for voltage telemetry in the CRSF reuse. Please set the ratio in EdgeTx to 20.

Setpoint Response time​

This per-axis parameter replaces the old "Setpoint Smoothness". It does exactly the same thing, but now has a physically meaningful value. It represents the speed the setpoint will converge to the commanded value in ms. It is important not to set much lower than the heli's natural reaction time. The default is 20ms for cyclic and 15ms for tail. Most helis simply can't move faster than this.

Setting this too low will cause unnecessary I-term windup and other PID issues.

Values higher than the heli's reaction time will simply slow it down even more. This is especially neat for scale flying, or just for the pilots preference.

CMS​

CMS is now disabled by default.

There is a Feature flag for enabling it. This will also enable the necessary stick commands - BE AWARE!

Servo limits​

Servo limits have been extended to 70deg, as requested. As before, they need to be adjusted if the default value is not suitable for the heli.
