I still need to add more pipes on the engine - as well as hoses -- I've never modelled hoses before so I'll have to look into it : ) Pipes are easier to do than organic, curvy stuff.
LLRV-1 initially had caster landing gears but I read that the LLRV tended to roll on the tarmac when gusts were strong that they had to replace the landing gears with those pogo sticks : )
