Hi - I have been experiencing intermitent stick spikes as of late. I have a full ch setup and my question is could it be pro throttle related?> I have good cooling going into the computer so i dont think heat is an issue. The setup worked fine until lately and when i checked it i sometimes get spikes from the throttle. I use win 98 and also when i go to game calibrate option it doesnt recognize the stick right away it takes a few seconds and then pops up "connected" on the calibrate section. It seems the more I fly the worse the spikes get, any help would be greatly appreciated Thank You.
