This is another cool Star Wars set for mashing into a Star Trek ship : )
All it needs is to grow a pair of warp engines, and flip it back to front once again, along with all its turrets. And if you've a spare pair of escape pods from the 75288 Escape Pod vs Dewback microfighters set, they look cool as the engines : )
MMM Star Trek Gunship LDR with step-by-steps. It's a little rickety though, and not swooshable; for display only... until someone rebuilds and reinforces its structure.
Here's the 75233a Droid Gunship LDR, converted from vean's LDD in EuroBricks forum. It seems modified from the original.
Thus, I've an updated copy closer to the original Lego build instructions, complete with build steps for the gunship.
Here's the Escape Pod alone from 75288 set.
PS: the orange mech in the photo is retired 70707 CLS-89 Eradicator Mech (from the old/discontinued Galaxy Squad theme), souped up with another gatling cannon. Really loved the use of brilliant colours in the Galaxy Squad theme, unlike the very grey hellscape of many Star Wars ships.

If you can't find the Droid Gunship anymore, there seems to be a WUHUI clone.
