It's an easy fix
Just select the whole rocket, Geometry Setting - Loosen.
No need to do anything more
Oh, My suggestions:
Make the floor / landing pad a "Killer" to reduce lag, The parachute springs need to be stronger = The parachute doesn't work.
Hope this helps

One bug I have found though.. The first spring block you get to can get you stuck in it (Happened twice)
Not sure how it happened but.. Not the most pleasant of things
