Only a few. might as well tell what I'm up to.
-iFalco V8 swap in an old Isubu (thanks to iFalco for the engine, it's small enough to be mobile friendly, but still very detailed. Go check it out.)
-FmgT T-88 and T-128 tanks (just need someone to make guns for them)
-A front engine jet fighter
-Inline 4 engine assembly
