Beta85X Setup Bidirectional DSHOT and RPM Filter (More Flight Time on Tiny whoops) (2 min 6 sec)


More flight time.
Cooler motor.

Step:
1.Update your BLHeli_32 ESC to version 32.7 or newer in order to use bidirectional DShot.
2.Update your FC to Betaflight 4.1 or newer
3.setup RPM filter.(suggest settings in the photo below)

Test use Beta75 pro 2,
Benefit from longer flight time and cooler motor.
More smoothly under 1S 0.5 startup power.

steps:
1.flashing the support bi-directional DShot firmware(for RPM filter),
download the latest firmware marked “48KHz”.
Firmware that allow to run RPM filter in BLHeli_S ESC for free JazzMaverick:https://github.com/JazzMaverick/BLHe...eli_S%20SiLabs

Firstly find out the code name of your ESC.
Connect to BLHeli Configurator.
You can see your ESC code name in the title, for example, mine Beta75 pro 2 is S-H-50 and download the firmware S_H_50_48_REV16_8.HEX

2.SETUP BETAFLIGHT RPM FILTER
Update your FC to Betaflight 4.1 or newer(for now mine is 4.1.6)

Use 4KHz gyro sampling rate and 4KHz looptime.DShot300 ESC Protocol.
Enable “Bidirectional DShot“, and set Motor poles (for example Beta75 pro 2 motor 08028 is 12 poles)

Under Dynamic Notch Filter:
(suggest)
Filter Range at LOW
Width Percent to 0
Q factor to 200
Min frequency to 90

If the motors are cool, it probably means you can reduce filtering further. But this time you can use the two sliders on the top of the filter tab – Gyro Filter Multiplier and D term filter multiplier.(I test it at 1.2 both)

Space Shuttle Maiden Flight (4 min 17 sec)


Unfortunately lost onboard camera with the Maiden Flight video.

After fix the head and wing,
I'll change the motor from 300 to 400 class with SUNNYSKY X2212-9 1400KV and 30A ESC,
Do some test for rolling and looping with more power.
Wait for see.
