Community
Thanks to everyone from the AWESOME Cleanflight community for code, artwork, support, ideas, feedback, and
everything else. Without you all this product would not exist.
Unauthorised illegal clones
Please note that unauthorised illegal clones are circulating which have sub-standard components and incorrect
wiring. Using clones does not help or support the Cleanflight project; in fact they hinders it due to the support
overhead. If you bought a SPRacingF3 from any Chinese retailers you have purchased a clone. There are no
official Chinese retailers.
If you purposely bought a clone board please consider supporting the Cleanflight project by buying from an
official retailer in future.
As of December 2015 clone boards can be recognised by the lack of the Cleanflight logo.
