If we did another mass launch we ought to use a lower average impulse
motor. Like a longburn K. Mine came of a little crooked, but it did
straighten after about 20 feet. I think it's just the large amount of
initial thrust is a bit much for the small punisher frame.
Also, not all the engines ere created equally. Three of them failed right
at launch, they all lit at different times, and so on.

I’m sure we can come up with things to investigate and even reduce this

Who’s interested in a Punisher 2 mass launch? I think we should use the
same K1440 engine and leave it up to each flyer if they are going to modify
the rail buttons, pad, whatever else. We have lots of time to collect
details on each project.
Chris, would it be possible to post some details of the AC stand used to
test for misalignments?
Do you think that creating a way to hold the rocket on the pad until max
thrust is achieved would help?
I’m wondering why David Reese has not joined this discussion because
wouldn’t he be one of the best people to advise on something like this?
Again, I think building a large launch pad/test stand for ROC launches
would be cool and we probably wouldn’t need the contribution of many people
to do it. We could use the pad at Black Rock for XPRS or BALLS. Again,
I’m offering to buy the trailer for the project.
