For Trooper multiball start, yes. 100%.
For random ball saves during mutilball it’s 95%.
It all has to do with the ball settling in before the launch occurs (ala Trooper ball loading) to make the autolauncher work as it should.
I bent those two forks six-ways-till-Sunday to get a consistent launch but so far it’s been fine with my last adjustment.
I had everything from airball launches to super rattley dribblers, to medium post bricks with each tweak I did. Once I started figuring out where the consistent sweet spot was for my particular autolauncher, I then turned to the coil settings and fine tuned the rest with pitch and level.
Seems like a lot of time spent but it was probably only 25 minutes.
I spent more time dremel polishing the cheap-ass 360 Newton centering/resting plates and hex nub that sits on the spoon to get the smoothest action I could out of what Stern spec’d for the game. That, and adjusting/replacing switches.
Now that it’s in the rearview, I can relax, drink a few Troopers and wait for my dark blue T-molding (hold the mustard Gary ) and Flipper Fidelity kit to show up in the mail to call this game officially, “dialed.”
On my premium it was the stock spring. Build date was May 30th.
