Note about the FC Firmware Preflashed to the Poly F405 V1.2

The default betaflight firmware version on the Poly V1.2 is 4.5.1, because the version limits and the product testing needs, the default settings are CRSF protocol and analog OSD mode. For HD digital and other receiver users, please reflash the firmware to include HD OSD options and other receiver protocols.

Note about the ESC firmware Preflashed to the Poly F405 V1.2

Since November 2024, the Poly F405 V1.2 AIO minimum start up power value is adjusted to 1010 and maximum startup power value is adjusted to 1080. This means that this setting should work well for many builds, in many cases, you don't need to adjust the startup power value manually.

For your rerference, for the first batch Poly F405 V1.2 AIO preflashed with V0.21 Bluejay ESC firmware, the startup power value is min1010, max1020.

----updated on 2024/11/25

The default Bluejay firmware on the Poly F405 V1.2 is 0.21. The start up power is lower than the previous version V0.16. If you find your motor doesn't spin up, please try to increase the start up power.

Check out the article below to see how to set up the startup power and motor idle.

Note for Motor Choice

1404 is the maximum motor size that the Poly F405 V1.2 supports. About the KV value, please avoid using high kv 1404/1303 motors, such as 1404 6000KV.  For the 1404 size motor, 3800kv is recommended.

Note for Capacitor Installation

Please solder the capacitor directly to the onboard capacitor soldering pad. We highly recommend that you do this when you build a 4S quad.

Note for Receiver and VTX Setup

Please power up the receiver and VTX by the battery during the binding and setup process. Because the 5V from USB does not power the receiver and VTX.

Note for Buzzer Choice

Only the buzzer with a built-in drive circuit can be used on this AIO flight controller. A common micro buzzer (that only has two legs and without PCB board) is incompatible with the Poly F405 2S-4S AIO. We have released the buzzer with a built-in driver circuit. Buy it here.
