英语翻译
我卖了4个遥控飞机给个老外,现在老外发了个邮件给我,我不知道他表达的具体意思是什么!急
I recently purchased 4 of the helicopters listed above.
Three of the four transmitter units supplied had the right hand vertical trimming switch (the one that controls the forward and backward motion of the helicopter) 'locked' in position.This means that that controller for the forward and backward motion cannot be trimmed.
I have two other helicopters of this sought,besides the ones I have just purchased,and both of those controllers can be trimmed on the forward/backward as well as the left/right controls.
Please advise what can be done about this.

Answer 1

他买了4个遥控飞机,其中三个右手边控制飞机前后飞行的按钮不能移动（被“锁住”在原来的位置上了）,导致飞机前后飞行的平衡不能控制
他还有两架这样的飞机,这6个前后平衡都有问题,那两架左右平衡控制也有问题,他问你这个怎么解决
