Now that I've built this, what should I do with it...

[Project Pluto]

I did just stack another lifter on top of it. A 7 mainsail onion. Launch was, well, less than ideal! It did make it to orbit before engaging the 2nd lifter, so, it can lift a tonne of weight. The second lifter almost made a direct ascent (or decent?) into the Sun. I think the periapsis was 800000 km. Had launch been perfect, no problems!

I just need to sort out the clipping issue with the decouplers. I'll start by inverting them so they stay attached to the plate as opposed to the orange tank. Failing that, I'll try stack separators. One must work!

One way to fix the decouplers clipping is to put struts from the top of the orange tank to the strutural plate, I use 2 per orange tank and it seems to fix the problem. I notice the decouplers tend to be elastic which causes your whole thing to wobble, the struts also help keep thing rigid. It's a somewhat part count heavy solution, if you have a better way let me know, but it seems to work for me.

As far as stats go, just try launching to LKO (70-80km) and show how much fuel you have left, that will give us a good indication. Also, what % of thrust does it take to leave the launch pad? You might experience better efficency by using Skippers on the outer rings.

Not sure how to post files. Advice and I'll happily do so!
