Hi there,
Klem and I posted somewhere on here about a fuel cock problem with the hurricane where it was unresponsive to mouse clicks and binds.
The problem is the following: If you disable "limited fuel" in realism then you can't operate the fuel cock.
Since the fuel cock in the campaign (this is the only game option i have tested) is set to off initially this causes serious problems for take off. Read:you can't
So be sure to set "limited fuel" to ON in realism menu untill the devs can fix this.
