ZYX 3.50 固件優化內容:
1.優化了鎖尾控制，提高鎖尾性能，自旋急停時更加硬朗，而不回彈。
2.優化了主旋翼控制，在做快速鐘擺等動作時，消除主旋翼的晃動。
3.加快了搖桿操縱的響應速度，讓直升機更加跟手。
4.優化了自旋修正，讓自旋更加穩定。
5.修改了搖桿的死區設定部分，讓搖桿的控制更順暢。

升級3.50後首次飛行注意事項：
1.如果首次飛行時出現快速抖動，先減小(相應軸)的D項參數。
2.尾舵機在中立點時，尾槳需要有8度左右的夾度。
3.自旋急停時，如果兩側剎車的速度不一致，可以調節相應方向的自旋剎車速度來解決,即"左自旋剎車速度"和"右自旋剎車速度"，參數越大，剎車越快。

1.Optimize the heading hold control, eliminate bouncing when spin brake.
2.Optimize the main rotor control, eliminate swing while tic toc.
3.Accelerate the response speed of joystick, so that the helicopter can follow your hands better.
4.Optimize the pirouette compensation to make pirouette flight more stable.
5.Improve the joystick dead band setting to make stick control smoother.

 First Flight Attention with 3.50 Version:
1.During first flight, if there are hunting or swing with you helicopter, please decrease the D gain on corresponding axis first.
2.When tail servo is on neutral point, set the tail pitch to be approximately 8°in the direction that compensates the main rotor torque by adjusting the linkage length.
3.If the brake speed of left and right pirouette are different, please adjust the "Deceleration L" or "Deceleration R". The higher parameter value, the break will be faster.
