Wil watch these when I get a moment.
They're strange kits aren't they. I couldn't believe the thickness of the plastic.
I've built the Gromit plane which is hanging from my wee fellas bedroom ceiling, (along with a Saturn V and a blue bag airfix spitfire, variety is the spice of life they say)

I have the motorbike and sidecar yet to build, the plane is essentially the sidecar with wings prop and tailpiece added and you have to cut out the wing outlets, the thing I enjoyed was you don't have to worry over filling gaps and the like, I worked on the principle that the wings etc slid out of the fuselage so you wouldn't expect a seamless fit.
