QX90 brushed FPV Racer 3D Druck

Hier stelle ich meinen 90mm Mikro Racer mit dem ich sehr zufrieden bin. Schnelle Reaktion, starke Bürstenmotoren ohne Eisenkern. Alles passiert auf Naze32 Flugkontroller und trotzdem extrem schnell, wendig und stark.
Er fliegt sich super zu Hause, als auch draußen. Es darf nur nicht windig sein. Natürlich ist der brushed Racer nicht so gut wie ein brushless, dafür aber um die hälfte günstiger.

Eachine ACRO NAZE32_BRUSH Flight Control
Dimension: 22mm*32.5mm
Thickness: 1.2mm
Weight: 3g
Features:
1. NAZE32_BRUSH is in the revision on the basis of NAZE32 flight control,it is a 32bit brush controller base on NAZE32 firmware .
2. The flight control support 1S (4.2V) and 2S (8.4V) power supply, 2S power can bring flying experience more violence.
3. Independent design of the circuit structure, comes with the pressure reduction technology, whether it is 1S or 2S power input, UART1/2 output 5V, UART3 output 3.3V
4. With a large current NMOS transistors, operating current of up to 10A or more.
5. Support for PPM, SBUS, DSM receiver input signal.
6. With battery voltage detection and buzzer interface.
7.In support of the world almost all hollow cup motor, including 1020 coreless motor.Support 6 motor.

Notice:
Before applying power, pay attention to the battery voltage selection.
The default shipping is 1S (4.2V); When using 2S, first need to disconnect the short contacts 1S, and then put the two pads on the 2S.
Prohibit shorted together the three pads at the same time.

Receiver configuration:
1. DSM receiver soldered directly to the DSM interface 3.3V, GND, RX2, in CF software configuration UART2 for Serial RX, and change the Receiver mode to RX_SERIAL,and then set up the receiver brand with Spektrum1024 or 2048.
2. SBUS receiver soldered on UART2 interface.SBUS signal in CF software configuration UART2 for Serial RX,and change the Receiver mode to RX_SERIAL,and then set up the receiver brand with SBUS.
3. PPM receiver soldered on PPM interface.No need to open RX Serial, just in the CF software to change the Receiver mode for RX_PPM.
Flashing with Betaflight 3.1 use NAZE32 flash image

Konfiguration

Ich bin mit den standard Werten bei Betaflight 3.1.5 geflogen. Und schon da flog der QX90 gut.

Auf dem FC habe ich Betaflight auf 3.1.5 aktualisiert. Hier meine Einstellungen (diff):
