Excellent point Kiteman on the engines on ships. Each to their own of course!
Bit more progress, quite a few bits stuck on this weekend. The undercarriage is the white metal stuff by Scale Aircraft Conversions. It is not as bendy as the original plastic stuff and the kit now stands nice and firmly on it's wheels. At first I used plastic kit parts for the nose wheel leg, as they are so much easier to use and reshape as necessary. However once on all three wheels - well it turned out it wasn't on all three wheels, it was a tailsitter. The kit supplies a nose weight - see previous instalments, but this turns out to be not heavy enough. My guess is this is because of the short nose on the A model compared to the D, which with all it's sensors etc should be a bit more front heavy. So out with the razor saw to cut the plastic leg off, cleaned up and painted the white metal parts and installed the new leg. And as you see from the photos, Robert is your avuncular relation, all three wheels on the deck.
I wouldn't bother with the white metal undercarriage normally, however in this case, due to the weakness of the plastic parts and the tailsitting it has done the job. More soon, happy modelling,
