Parameter explanation：
●
Frame type：Choose frame type of your quadcopter
1.Quad-X：X type quadcopter
2.Quad-cross：Cross type quadcopter
●
Receiver type：Choose receiver type
1.PWM receiver：PWM receiver
2.SBUS receiver：SBUS receiver
●
Idle speed：Defines the motor speed when copter is armed.
1.Off：Motor not moved
2.Low：Motor keep low speed
3.Normal：Motor keep medium speed
4.High ：Motor keep high speed
●
Basic gain: Most crucial parameters, direct affect flying performance. Usually, larger
copter needs larger basic gains. The default settings are optimized for 250 size
quadcopters.
●
Angular rate limit: These parameters decide maximum rotating speed your copter can
reach on manual mode. The higher these parameters are set, the more manoeuvrable you
copter will be. If you want do flips and rolls, it’s better to set over 300.
●
Angle limit: Maximum angle of each axis of your copter can achieve on auto level
mode, you can increase these if you want fast fly on auto level mode.
●
Attitude gain: You can get quick response of the copter to your controls if you increase

Angle trim: These parameters are used to compensate angle bias on auto level flying
(usually caused by inaccuracy of the mounting surface). During auto level flying, if you
put aileron stick on its neutral but the copter still drift left, you can increase roll angle
trim to eliminate this, otherwise the opposite; if you put elevator stick on its neutral but
the copter still drift backward, you can increase pitch angle trim to eliminate this,
otherwise the opposite
MG25 can also be connected with FC53 programming card for field setting. Please
refer FC53 instruction manual for more details.
