Heya ThreeUp,
I myself am also Left Handed, although back when I started using joysticks for flight sims, their was only the Flight stick Pro that even came close to being usable for Left handed people...... so I taught myself since 93/94 to use the Combat and then the FighterStick products by Ch......
I have been doing so for a good while now, although I am left handed, I use the complete CH HOTAS setup CH FiterStick, Pro Throttle, Pedals....
if you indeed need to use them in a left hand dominant compacity, then you migtht as well go all in and hvae "HomeBoy" custom fit you a Left handed CH HOTAS set ( CH Fighter Stick & CH Pro Throttle for Leftys )
I just now moved my Pro Throttle to the right side and even turned it around, and I seriously doubt it would be useful in any way using it with the right hand.....
you could take on this endeavor yourself and "custom build" yourself your own Right handed throttle...... just to see what you might come up with...
their are all kinds of different potentio meters, pots, modules, hall sensors etc.... readily available if you wanted to give it a go and experiment.... you can pick up all sorts of game controllers, joysticks, throttles, etc at thrift stores, goodwill stores, craigs list, ebay etc.......
but if it were me, I would try and scrape up the funds and have homeBoy craft me my own prsona CH Lefty Hotas.....
best of luck to ya....
