I've got the same problem with my throttle totally dead now.
However I updated the firware to 10 and 18 the day I got the HOTAS and it ran fine for about 3 weeks until this morning the throttle is dead :mad:
Contacted TM and after some troubleshooting they told me it was dead and they want me to send it back to them in France but just the throttle, so that they can analys it to see what the problem is because so they say this is very very 'rare'!
mmmm not so sure about that after reading the forums but they did say they will refund all delivery costs that I encure we will wait and see I guess.
Annoying though as I took 3 days off work was gonna spend time simming now looks like I have to do some DIY around the house instead!
