Ok, I've had a Homer moment, I admit it.
Ever since getting my Cougar out of the box, I thought man, this throttle is stiff to move back and forward, but thought it must be part of the setup as never actually used an F16 throttle.
I was dusting the outside of the throttle block and noticed a little dial wheel and thought, hmm i wonder what that does and lo and behold, it tightens or loosens the throttle stick.
DOH!!!
Ok, let the insults flow.....
