Brushless Drive Issues

So heres the situation.  My students have adapted Neu motors 1100 series with hall sensors to Banebots P60 gearboxes.  We at the moment have the motors mounted and are running each of the motors to separate Mamba Max Pro ESC's.  We are stuck with this situation.  We generally use the ELEV channel to move both motors forward/backwards and AILE right and left with our brushed system with THRO controlling our weapon motor.  We are now running two seperate ESC's, one to each motor.  How do we connect this all together so ELEV controls both motors forward/reverse, and AILE controls a left turn and right and we can still control our weapon motor with THRO channel?  Any help would be awesome as we are at a block.

Thanks.  We got the mixing figured out at the end of the week and the kids did the tuning on the bot.  0-20 ft in 2.2 seconds with no cutout from the weapon and or wheels.  Ran weapon at 7000-10000 rpm and wheels full throttle for 3 min and drained a total of 1.5 volts from the batteries.  Needless to say we will be sticking with brushless drive systems as long as the funding is there.

Would you mind sharing your motors you use for your brushless drive? we went with a hobbyking motor and wasn't too thrilled with the results.
