This is the Happymodel Snapper7 the slightly larger Tiny Whoop with aluminum propeller protection and especially with brushless motors and 1S LiPo. My quadcopter has a FrSky receiver integrated on the F3 flight controller with telemetry!. The Whoop is available with Flysky or FrSky receiver which transmits all telemetry data to the spark. In the Flysky version, RSSI and the voltage are sent to the remote control. The canopy is made of hard, transparent plastic. The Happymodel motor is a small 0703 motor with 19000KV perfect for the 75mm frame. Optionally there is a plastic frame to make the Tiny Whoop even lighter.
