Guys how do we test if the receiver and the transmitter is working, allthough when the receiver is switched on the servos move a small amount but how can we check for sure whether or not our radio and crystals are fine or not.thanks for the advices

Umm.. If you have a friend try to bind it with his tx/rx. Did you try it?

thanks for such an early response but i dont have anyone here in my area who is into RC stuff. As i am a begineer what do u mean by "try to bind it with his tx/rx" 

Well Binding is only for 2.4Ghz Tx/Rx systems. Once you bind the tx to your rx, the rx will only accepts commands from the binded tx. That means you will be interference free.

But if you have a regular Tx you have to make sure no one is flying a model with your same frequency. Like if you have a 72Mhz Tx your friends cannot fly with you if his tx is 72Mhz. You will get interference and will crash or put your or your friends model in danger.

As long as you dont have any instruments to test the transmission of your Tx, using your friends is the best option. If you are convinced that your Tx and rx is malfunctional. Ask the forum members with similar radio tx to test it whether its functional or not. You might have to send it to them. Its all a matter of trust

Thans pal

Even in 72 MHz frequency there are 50 channels. Problems occur only if more than one flyer are flying on the same channel only.
