Rice32 mini F3 Flight Controller - Flight Controller - HolyBro - NewBeeDrone FPV Shop - 1

Rice32 mini F3 Flight Controller

$ 39.99

The little brother of the Race32 by Holybro, this is the exact same flight controller, but in a smaller form factor for micro quads. The Rice32 F3 features the new STM32 F3 processor (upgrade from the F1 based Naze based boards) capable of super fast loop times and fast floating point calculations, allowing you to utilize the LuxFLoat controller in Betaflight, Cleanflight, or Raceflight (Betaflight recommended).

Please use the SPRACINGF3.hex version of Cleanflight/Betaflight to flash this board (DO NOT the EVO or MINI versions as they will not work correctly)

The majority of quads fly solid with the default LuxFloat PIDS, reducing the amount of tuning required and getting up in the air much quicker than before. 

Features 8MB of flash memory to record your flights for later tuning via the BlackBox feature. Also, custom ports that minimize soldering, and a stack-able design to use with HoylBro's line of PDB and OSD modules (coming soon). 

The Rice32 F3 Flight Controller was designed to give awesome flight performance based on tried and tested sensors whilst also providing unparalleled I/O capabilities in a small and extremely lightweight form-factor.

For steady, locked in performance, and our guarantee that it will not burn out, look no further than this great performing high end FC.

 Comes with protective case, our product guarantee, and all necessary wires to connect to PWM, PPM, ESCs, Power Distribution board (coming soon), OSD and Telemetry (coming soon), LEDs, and GPS.

    What about Free Shipping?

    We get this request from our customers a lot, and we are working hard towards our goal of being able to offer Free Shipping for our orders, but we are not quite there yet. We are still a new shop that has only been open for less than a year and we are not quite up to the order volumes required to be able to offer Free Shipping. 

    But the more awesome customers that we get, such as yourself, the faster we can reach our goal! 

    How much is it to ship to my home?

    Want to see the rate you would get? Its simple! Just add the desired items to your cart and initiate the checkout process. Once you have entered your address you will see the best rates that we can generate for you on the next screen.

    Where is my shipment?

    We send an email out with a tracking number for every order that we ship! You can log into your account to find a specific order #, and then just search your email inbox for that number to find the tracking email from us!

    What if my package is lost?

    If you used the US Post Office to ship your package and it has not arrived, it is your responsibility to reach out to the Post Office and open a case with them. We are not responsible for lost packages and cannot issue refunds due to such a situation. We drop all our USPS mail at our local Post Office and as soon as the label is scanned it becomes the responsibility of the Post Office and the customer.
