Holybro's latest racing drone has been designed to sit within the sub 250g weight category, but to deliver the speed and agility of a larger drone. The Kopis Racing 3inch drone only weighs 145 grams. Considering that a 4S 850mAh LIPO battery weighs around 100 grams, the total take-off weight of the Kopis Racing 3 remains under 250g.
As with all Kopis series racing drones, this drone is built from high quality components. The Holybro Kopis Racing 3″ is built on a robust 137mm size carbon fiber frame with 4mm thick arms. Its powerful F1507 KV3800 brushless motors are paired with 3-leaf propellers. The flight stack consists of a Kakute F7 Mini V3 flight controller and Tekko32 F3 4in1 35A mini ESC board.

You must use a receiver that supports a serial protocol such as SBUS, iBus, and Spektrum Satellite. You cannot use a PPM or PWM receiver with the Kakute flight controller on the KOPIS.
