It has the look of a paper airplane. Yet the X39 is made of polystyrene! With a wingspan of 39 cm and a length of 32 cm, it is equipped with two brushed 720 motors for two 4.6 cm propellers and two 2g servos to operate the ailerons. It is thus similar to a flying wing. The battery is a Lipo 1S 3,7V of 380 mAh 25C. A component all in one takes care of the radio part, the piloting of the motors, the servos and the power supply. The whole weighs 58 grams at takeoff.
So it’s up to you to assemble it. Don’t panic, the puzzle is quite easy to put together, all you need is a little glue. A mode 2 radio control is delivered with the device. According to XFRC, the X39 is able to behave like a wing, flying backwards, with rolls, etc. The price? The device is offered with its radio control at $84.69 at Banggood.
