I had a problem with my receiver its a 2.4 ghz receiver when I give steering the the throttle also work so I reconnect and bind the receiver it won't work what may be the reason pls tell me and tell me a suitable remedy...  

The reason that your throttle servo works when your steering(my friend had this problem) is applied because the servos consume more current and the battery is not capable of providing it..but the receiver will not be affected by this.Try binding without connecting the servo..
BTW please specify your Tx and Rx model , channels...

Its not working when I connect the battery alone....its a 3-channel receiver....
