Just tried 5K and love the way the first main fuel rocket stage wobbles like three loose legs. ;D

Was about to ask how you got the stage numbers (4+5+6) that are underneath the first/bottom stage, as building an identical rocket it doesn't get those 'extra' numbers and still won't lift off the pad?

;D Yeah, just realised that when I removed them and it stayed rooted to the pad. :-[

I guess the decouplers as the bottom/first stage aren't actually required, as they stay on the launch pad due to being the first part activated at launch.
