Introduction
The realization of FPV flying starts from having a SunFounder 250 aircraft. The SunFounder 250 Quadcopter is tailored for the hobbyists for FPV flying. It
features stability, flexibility and activity. You can realize a stable flight in a high or low altitude or in a forest with the SunFounder 250. The skid landing
damping sponge tubes bound onto the motors help stablize the flight and protect the frame through increasing the buffer between the frame and the land
when the aircraft is landing.
It runs the OpenPilot firmware of the flight controller firmware and the 12A SUNFOUNDER brushless electronic speed controller. This kit is designed to
meet the hobbyists' higher requirement of flying the aircraft. You can realize a stable flight in a small space or a rapid 3D flight based on your own
configuration and parameter setting.
Note: If the motor and ESC in the kit you received are both carrying SUNFOUNDER logo, then you receive the SF250 V2.0. The assemly procedures are
the same with V1.0 version, please refer to the video below : https://www.sunfounder.com/video/category/?cat=40

Test by multimeter: set the multimeter to the 200Ω setting to measure the direct-current resistance of the motors’ three-phrase winding - check two wires from three each time as shown below. The measured results of three times should be very close to each other. If the gap among the results is more than 10%, an inter-turn short circuit may have happened between the wires with the smallest result. -
