Yea, You can loosen up the screws and it releives the pressure somewhat on the return spring.
Even if You take the screw completely out, there is still plenty of resistance to ensure positive home position.

I pulled the springs further by stretching them until the coils didn't touch anymore, BUT NO MORE THAN THAT !

Then, I re-inserted the springs, and the tension screws and TIGHTENED the screws until it wasn't total mush and would return to the dwell in the tension armature. Now it just takes the lightest touch.

The results are REMARKABLE, as now I control the whole spectrum of inputs, and not enslaved by a dwell in the ratchet, or waiting until you break through the 'no response' envelope or dead spot. I can keep a perfect hover, keep the nose where I want, and the flight characteristics smooth out to unbelievable realism.

Then I noticed too big of a dead spot for the inputs; kinda defeatest, so I moved out the servo linkages out 1 hole for a more positive response.

I might note that it is important to read the guide described in this forum and get the pots in the 4-1 spot on before doing this mod.
