Nach den ersten Versuchen im Jahr 2016 mit zwei Bixler3 von Hobbyking, sind wir jetzt auf die [[https://www.banggood.com/de/X-uav-Mini-Talon-EPO-1300mm-Wingspan-V-tail-FPV-Plane-Aircraft-Kit-p-983331.html|XUAV Mini Talon]] umgestiegen. Das Flugzeug hat eine Spannweite von 1300mm und eine Länge von 830mm. Die Komponenten dazu sind

==== X-UAV Mini Talon ====

The airfoil of the X-UAV Mini Talon is a [[http://airfoiltools.com/airfoil/details?airfoil=s3010-il|S3010]] with 270mm chord length. The pitch is approximately 3°. This airfoil is similar to the S3021 and the Clark-Y. The airfoil is optimised for low Reynold numbers, i.e. small wings and low speeds. The wing of the Mini Talon has a length of approx. 270mm at the fuselage. The Reynolds number is approx. R = v * l * 70 when v is the speed in m/s and l is the length in mm. At a speed of 8m/s this translates to a Reynolds number of approx. 150000.

=== Power Modules ===

I have purchased some other power modules for the pixracer as the original power module is only available from mRobotics.

  * [[https://de.aliexpress.com/item/32802861509.html|APM Power Module for PixRacer]] for 7,10 Euro. With Hirose DF13 connector on the board and DF13 to JST-GH cable. 2 modules purchased on Aliexpress on 18.4.2019.
  * [[https://www.ebay.de/itm/253298947513|APM Power Module for PixHawk]] for 4,02 Euro. Hirose DF13 connector on board and on cable. Needs different cable to connect to PixRacer. 3 modules purchased on 18.4.2019.
