Update - Yes. it can carry an orange tank to orbit ! I had a few issues in this vid getting sufficiently fine pitch control with the action groups, possibly because i’d put the payload slightly too far aft (making it pitch up more) and also i had the authority of the outboard canards (which are controlled by AG) set to 100%, and didn’t realise that was the problem till the end of the flight (finally lowering the authority on these things).

Still made it to orbit pretty easily, though getting the payload out wasn’t straightforward.

Update 22 June 2018 - Craft found to have rearward shift in CG when empty , slight but given marginal stability to begin with, not acceptable. Have improved stability now, but since CorrectCoL no longer works on KSP 1.4x, it’s a lot of trial and error. Changes have reduced roll rate and i need to confirm handling on zero fuel situation with more flight testing.
