Hi computerx.
I love sputnik velcro rockets addon.
If I combine that addon with the Universal cargo deck add I can create many concepts. My problem start when I want the boosters to ignite at the same time. I use vessel control to do this, but must ignite them one for one. I thought that maybe in feature version (if there is any), I can ignite them all by combine the boosters, or whatever, at the same time.
