You bet he can use throttle, peds with sidewinder.
They should all be USB devices, plug, calibrate in windows and AH and setup the way you want.
I've heard a rumor, that X52 throttles have a Midi port for the old style Gameport joystick connection. That actually lets you plug a joystick with gameport plug into the throttle. In which case there is a ton of MS sidewinder Precision Pro's out there going for cheap.
My wife brings em home from the second hand store for 2 - 3 dollars each. But they are not USB so most don't want them. Although I did sell a pair to Sloehand.
