Hi,
can someone suggest on how to put two ESC and two motor in one receiver and can be controlled with a simple 4 channel tx system. my main moto is to put two motors (counter rotating) in one plane which can be maneuvered by simply increasing or deceasing the speed of individual motor.

you need something like a v-tail mixer, this will control the motors normally when only throttle stick is used and when aileron stick moves if generate a difference control which can create roll movement on the plane

or i don't know let's see what others suggest

Sandeep ,

Two Motors on 1 receiver where both ESC's have built in BEC's is as per this diagram ( courtesy Rajeev Ramachandran)
Basicall you cut off the +ve of one ESC so that only the other ESC powers the receiver . You could use a Y connector to connect the 2 ESC's to the Throttle channel.

In case of more powerful set ups where ESC's don't have BEC  the 2 ESC's are connected to the throttle with a Y connector and  a separate power source is provided for the receiver.

This is for conventional 2 motor set ups for the type you are talking about I dont know

Sandeep needed yaw control with motor. VTAIL mixer should work. But if you need such a plane, get the cheap chinese toys, they work like this. I hate to fly these planes, they are hard to recover from if they bank too much. Every once in a while, there is somebody at the field with these planes looking for somebody to test fly them. I have learnt to disappear from the scene when this happens since I hate crashing others models.

In my opinion, you should have aileron and elevator controls for good control. Rudder instead of aileron will work in planes with high dihedral.
