Floureon K250 Updated Version Of The 250 Racer


The new Floureon K250 is now available, and brings a few very welcome updates to the tried, and true Racer 250 platform. Click me to purchase.

This new version replaces the 2204 motors of the old 250 racer with 2205 2300kv motors. The old Naze32 flight controller has been updated to an SP Racing F3 FC with OSD. The 1000TVL FPV camera gives a clear, and clean FPV feed, and the new Pagoda FPV antenna gives an improved range with better signal quality.

One of my favorite things about these quads are the lights. The headlights are very bright, and the LED light bar on the back looks extremely cool during night flights. (See pics) They also aid in keeping correct orientation at distances when flying LOS.

These quads are excellent for anyone looking at getting into FPV flight, or those that just want a cool looking drone to fly around the yard, or local park. This K250 Racer is available as a Flysky, or Frsky BNF, or as a PNP model ready for your own choice of receiver. This is also one of the most affordable 250mm quadcopters with the PNP version costing only $121.99 and the BNF versions costing $130.99

I just finished getting mine set up in CleanFlight, and will get some flight video ASAP so stay tuned for updates as I spend some time with the quad.

Ended up flashing a newer version of CleanFlight, and finally got around to getting it set up and getting a test flight in. Here is the LOS test flight video. More flight video coming shortly.

Another LOS flight on 3s with the stock props. Very fun quad to fly!

Printed a few bits for the Floureon K250 Made a case for the low voltage alarm, and the HD camera mount to replace the original camera mounting plate.

The alarm case can be found here, and the camera mount can be found here.

Flight footage from the HD camera coming soon!

Here is a CLI dump after I upgraded the firmware on the FC to CF 2.1 in case anyone needs it.
