401于750的实质区别

1.用401飞自旋动作相对柔和，用750的话会有硬邦邦的感觉
2.用401飞自旋，停车的时候刹车比较柔和，用750飞同样动作刹车比较快

本质上说两种陀螺仪没有区别，只是算法不同而已
如果喜欢飞的优雅一些，401是不二选择，反之选GP750

Futaba Corporation (双葉電子工業株式会社 ,Futabadenshikougyoukoujoukaisha?) (lit. Futuba electronics manufacturing corporation) TYO: 6986 is a Japanese company that manufactures popular hobby-grade radio control systems including transmitters, receivers, servos, electronics and model aircraft. These products are used as the electronic link between the person controlling a model aircraft and the ground and the actual remote control system in the vehicle. Futaba was created in 1948.

Over a quarter of a century ago, Futaba became one of the first companies of its type to provide comprehensive radio control products, selection and service to hobbyists. Futaba systems and products were quickly accepted and used by serious competitors and casual enthusiasts alike.
