The HOTAS X is a 4-axis controller. It has a rudder rocker on the underside of the throttle:
Also, the stick twists as well - the switch in the picture selects between the rudder on the throttle or stick twist.
It is also AKA the Thrustmaster Top Gun Afterburner II
Quite crappy innards, but reasonably unique in having the rudder control and it really works rather well for MWO. Also worth noting that the stick and throttle separate, so you can use the throttle with a mouse without having to have the stick part in front of you (but it does need to be plugged in)
However the rudder will go quite quickly and provide inaccurate results.
I am thinking of modding mine to Hall Sensors as I really can find little else that compares to the layout of the throttle unit.
Also, an XBOX controller can work OK as a left-hand device. I have code
here that converts an xbox controller into a relative throttle plus absolute rudder, and fixes a number of other issues with using them for MWO.
The logitech G13 keyboard is also not bad as a left-hand device, although you will need to mod the thumbstick (as in the physical form, not a mechanical or electronic mod) to make it work well as the stock one is too pointy.
