You probably have the Venom Fail Safe, like me, but I may be wrong. Most failsafes are tunable by pressing a button on the failsafe while holding brake on your transmitter. It will save that position so when you lose signal, the failsafe will automatically adjust the servo into brakes position. The other type on the one where it uses a knob. Mine has a flat head adjustment screw, and all you have to do is stick a screwdriver down the hole and adjust it. When I turn the screw counter-clockwise or clockwise the position will be set where I stop the adjustment of the screw as the servo moves along when I turn the screw.
