dual esc's on a JR xs3?

[stanmondz]

the manual says it can do 4ws. so could it do 2 esc's? i dont think it could do any kind of dig though
i copied this from the JR manual

The XS3 offers two different mixing adjustments that allows
for mixing one channel to another channel. The mixes
available are Steering-to-Auxiliary Channel Mixing and
Throttle-to-Auxiliary Channel Mixing. Each direction is
independently adjustable. Popular use of this function
includes 4-wheel steering and independent front and rear
wheel brakes.
For example, Throttle-to-Auxiliary channel mixing can be
used for independent front and rear wheel brakes. Each
time the throttle/brakes is moved, the auxiliary channel will
move in the direction and to the value input being given by
the throttle channel. Mixing is proportional, so small inputs
to the throttle will result in small output from the auxiliary
channel. The adjustment range is from -125% to 0% to
125%. If the rate is negative, the channel is mixed in the
opposite direction.
Both mixes share a single mixing “offset.” The purpose of
the mixing offset is to redefine the neutral position of the
auxiliary channel, which can be set using Grip Lever A
when “LN” is selected in the Auxiliary Channel 3 function.
If the “LN” selection is turned off in the Auxiliary Channel 3
function with a offset value currently present, the value will
continue to act as a mixing offset until the value is either
cleared or changed. If a mix is not required, it is strongly
suggested the mixing rate be set for 0%, which is the
default.
