Had to do some micro-engineering on the skis. Firstly, the nosewheel needed a brass axle:
Then I hit a serious problem with the main gear. The standard Twotter ski has a pair of pyramid-shaped struts which go either side of the wheel, which is on the end of a long, thin pylon. Unfortunately, the Skyvan wheel sits on a vertical "fin" on the end of a short sponson. The inner pyramid strut wouldn't fit between the wheel and the fin, and the struts wern't wide enough to fit around the wheel and the fin.
Looking at a cutaway of the landing gear, I realised that the latter option was technically credible if a hole were cut in the inboard skin of the fin, so I set about modifying the skis with an offset inboard strut. The Revellobox ski struts are just plain triangles with no axle attachement, and the stub axle is too wide to fit in them, so I made the axle of alloy tube and put a brass rod through the middle of it, which sits in drilled holes that JUST fit in the tips of the triangles.
Here are the exhaust pipes treated with Humbrol Metalcote Steel. The holes in the nacelles are nowhere near big enough to take them, so that was another tricky fettling job:
Quite please with how the sledge turned out. Here's what you get (everything moulded in two halves, solid handle etc..):
And here's the end result, with a hollowed-out handle and my best shot at making the cargo items look separate from the frame and each other:
The fuselage is currently glued and clamped and taped together. Had lots of fit issues there: this kits turns out to be quite a bit more warped than the last Skyvan I built.
