The rig "legs" were black plastic piping for sprinkler systems.
I had spare time so I thought I'd paint on a bit of detail and stay under my 30 minute limit.
Kinda regret I did though - it looks rather cartoon-y. Also making the helipad so garishly obvious precludes the use of the rig for VSF aeronef gaming...
The jets are Tumbling Dice 1:600 and are always a pleasure to paint.
I've got plans for the oil rig for an alternate-future 1970s which involves aerial wormholes, resource-rich planets and mercenary air forces. Think Area 88 meets Yukikaze.
Yukikaze had wormholes that appeared over Antarctica. They lead through to an alien planet which humanity invades through the wormhole. Lots of cool dogfights. Weird incomprehensible plot.
Area 88 has a mercenary air force fighting in some un-named African/Middle Eastern country. Awesome 1970s dogfights with an annoyingly angsty, whiny, Japanese teen protagonist.
