The Rekon4 FR HD is a 4" BNF Quad with a robust frame, quick-swap arms, and a Sub250 weight goal. This quad was designed to create a sub 250g freestyle platform that gets as close as possible to a “classic” five-inch quad. And while performance was the main objective, Rekon FPV still wanted it to be practical for everyday use.

The motor and propeller configuration was crucial to achieving the desired flight characteristics. After weeks of testing, Rekon FPV finally settled for an intermediate stator size with an aggressive kV. A stator larger than 1804 (e.g. 1606, 2004, 2204) didn’t seem to offer any noticeable improvement of flight characteristics while adding a significant amount of weight. Anything smaller than 1804 just did not have enough torque to make the quad feel locked and snappy enough. 

The best performing props were the Gemfan 4023 tribades. They are more on the aggressive side in comparison to the HQ T4x2x3 and while they can be pretty amp hungry on the relatively high kV 1804 motors, they ensure the quad has an impressive punch!
