i am trying to control my quad and tanker through two transmitter modules and two receivers modules but a single REMOTE is that possible

How will you connect two transmitter modules to the same transmitter concurrently ?

Also, why are you complicating your life by trying to run two things at the same time ? If you are going to have only one thing working at a time, then most radios these days support multiple models, so it is common use case.

hmm but iam building a quad that flys and even moves on land, i need 9ch for quad and 6 ch for land
my friend suggested to me to go with two radio controls , i just have a doubt can i use a single 9ch for both
note:here the operation is not simultanious i just fly or just move

Then you need two receivers.  Program two models in the radio. Choose the quad and fly the quad, when you are done, choose the tank and drive it.

BTW, why do you need 9 channels for a quad ?  4 or 5 is enough usually (although you can do more with more channels).

Anwar, one doubt? we will need to restart TX & RX to change the mode right?

Depends on which radio. Here is one scenario.

Say you are on a Spektrum system with model match. It is important to program proper failsafe for both receivers. So you start the TX with the quad model, and power on the QuadTanker.  The quad will respond, while the tank will be in failsafe.  After you land the quad, you switch the model to tank.  Now the quad will go into failsafe, and you can control the tank.

I can't remember if you have to power down the Spektrum TX to change models, I think the earlier models needed that. I am a Futaba person, but I think the newer Spektrums are capable of switching models directly from the transmitter console.

So there is at least one way to do this, with the right equipment. 

There are other choices also.  For example, say you have a Futaba transmitter and receiver with lots of channels (like 14 of them). When you wire the QuadTanker, use the first set of channels to control the quad, and later set of channels for the tank.  Now you can use programmable mixes to feed the stick movements from the lower set of channels to the higher set of channels, and control them both at the flick of a switch (but one at a time).

oh thats great it works

anwar can you please tell me from basic on what should i do to get this done
please tell me what i need and how should i make this work
thank you

Huh 

Didn't I just say what needs to be done (or at least I tried to) ?

I can tell you one thing that you need to do.  You need to read/research a lot.  A LOT !  And there is no shortcut to that.

Thanks for info Anwar.

Do you think we may also need to consider the FC?

I am just guessing this by reading this thread.

thoughts?

oh sorry i ask you that i was just curious to know about it
nyways thanks for the response it will help

I am not sure I understand.  What about the FC ?

well, i mean do we need to do any sort for special setting for fail safe in advance FC board like DGI naza or APM 2.5?

I have HK green board and know that it just follow the RX command so if link goes down and RX has fail safe setting then basic FC will follow the RX setting .

So, will it work same way on advance FC ?

Naza as a special way of setting failsafe, which can be triggered via a switch, or triggered automatically when TX signal fails.  The procedure is mentioned in the setup instructions. If you want to know the details, just search on Youtube for "naza failsafe" (there is one video from Alishan Mao which I can remember, it was pretty good).

make sense !

Thank you
