F121: the best choice for Education and Training
Altitude holding by inertial navigation and PID autotuned makes it easy from zero to hero.
The size is small and easy to carry makes pilots fully enjoyed even with small space indoor.
The flight controller F120 developed by RadioLink combines Kalman filtering technology and inertial navigation algorithm (gyro+accelerometer+barometer), allowing F121 flight with accurate altitude hold even through narrow space or no matter how close to the surface (less than 10 centimeters height).
