Swapping Channel 1 and 2 I get this. With right forward/reverse stick applied I get both tracks moving together and can swap around the polarity to make them go in the proper direction. Right stick left/right produces single track movement (Right stick left track forward - Left stick right track forward) and recoil remains the same.
run calibration with this last setup and should work, it is not a powertrain mosfet issue otherwise running forward/backwards (with this setup) one of the tracks wont run.
Make also sure that the "PowerRotation" is set to 100

Hi Seems like you have got it just need to fine tune it, Once you get it working right make a copy of your Sd card settings and save them on your computer under a named file so you have it in case you alter something and cant remember your original settings. Then you can customise your settings on your sd card power settings momentum or other changes you do .

In configuration #2 (1 in 2 and 2 in 1) I can configure motor wires to drive the tank but the tank steers with only one track at a time and does not spin!! Recoil remains on the left motor channel only and it lose all steering while in forward or reverse. Also if I adjust power-rotation it effects the forward and reverse drive speed.

I answered the same issue on facebook the other day.

Change the + - on one motor and swap the left right/forward back feed on the RX

Done and reverts back to original issue. Spin works great and can be controlled thru powerrotaton but forward and reverse is single track. (Forward produces left track forward and NO right track movement) (Reverse produces right track reverse and NO left track movement) recoil still remains on the left motor channel only and is in the proper direction.

I am suspecting that this is a combination of motor wiring and channel configuration. There is slow turn, and superspin. What you are seeing on the wrong stick position is slow turn (one track moves) and superspin (both tracks move but in opposite directions). This means that the left/right and diagonal stick positions are hooked up to the wrong channels. Make a chart, and tape numbers 1-4 to the plugs, and systematically mark which plug goes to each rx channel, each time you move them to a new channel, note it on the chart, that way you won't repeat combinations that don't work.

Eg
rx plug combinations
C1 1 2 3 4 1
C2 2 3 4 1 3
C3 3 4 1 2 4
C4 4 1 2 3 2

Keep going until you find the magic combination, the key one is the tank start up being in the correct position.

If both motors go forwards and backwards, eg while on superspin, then it would appear that all of the FETS are ok.

I have had similar issues when setting up a tank, and it can be as confusing as heck, but there is really no alternative to setting up the tx/rx to a known channel configuration, and then swapping the motor wire +/-, and/or the plugs, until the motors are both turning the correct way.

It is trial and error. To speed up the process you can run the motor wires through a screw type terminal connector as this will enable you to swap the wires around with ease. Just make sure that you keep each motor +/- going to the respective plugs.
