Hi, I’ve been working on a recreation of SpaceX’s Starship/ITS/BFR, and I was making a pad to test staging and engine run time, and found that it disconnects (Which results in a big explosion) at start. I was wondering someone could help explain why that is happening, or even perhaps fix it. Thank you. The craft is in my profile.

if you have an added interstage underneath, the rocket engines need to build up thrust for a second or so(depending on the engine type) - activate the engines with the first stage, wait until the TWR is above 1, then activate the interstage...and it should work

What disconnects, I launched it from the launch pad it worked perfectly

It turns out my rocket had a bit of bounce at load, so I've added landing legs and the problem is fixed.
