Yea, those two fixed forward links were bending aft when my servo pushed up. I was amazed to see the servo fighting the two links. Too many pivot points, so I just gave up and removed the two forward links.

Loosen the screws and watch them bend. Especially if you added more forward pitch.

I guess you saw that the forward links are keyed on the bottom. Turning them so the keys face outward didn't work for some reason.

Like a rocker arm. The servo pushes up from the back, making the front move down. Except the front can't move down because of the fixed links. So the swashplate moves up which decreases the distance between the rotor mast and the two forward links, except the distance is fixed because of the two fixed forward links. Either the rotor mast is going to bend or the two fixed links are going to bend. The rotor mast won't bend, so the fixed links have to.
