The Monkie Kid Cloud Jet is so cool! So couldn't resist mashing it with the Droid Gunship.
It is made up of the main engine body of Cloud Jet, main saucer of Droid Gunship and some spare bricks to join them.
Here it is alongside the prior Cloud+Asgard, red USS Vengeance MMM:
PS: knocked off an engine flame piece and engine handle piece - and can't find them yet XD
The bridge has been raised and turrets attached to the saucer (primary hull). The Droid Gunship has a lot of firepower and they've carried over to the Star Trek Destroyer =)
The secondary hull could be more securely attached, so may need more work on it. Saucer is not detachable at the moment as the interface to the saucer is somewhat rickety.
Star Trek Destroyer, Monkie class, MMM LDR:
Build is organized step by step, so you can follow and build yours.
Its sister ship is here (the one on the right side of the 2nd photo).
