There are, sometimes, a few small radio-controlled helicopters that appear, despite a market for rotary wings totally dominated by drones. This K124 from XK matches the look of the EC145. It is equipped with a 4 blade rotor driven by a 1106 to 11000KV brushless motor. The anti-torque rotor is based on an 8520 brushed motor and measures 25 x 23.2 x 7.7 cm and weighs 85.5 grams.
The remote control is an XK compatible with the Futaba S-FHSS protocol. The battery provided, or rather the batteries since there are 4 in the box, are Lipo 1S 3.7V 700 mAh 25C Lipo 1S for an autonomy of about 5 minutes. The aircraft is designed for both beginners, with a stabilized mode, and experienced pilots capable of back flying and acrobatic tricks. The price? About $149.99 at Banggood. Or $124.99 if you choose the BnF version, without remote control.
