3 different plans- 1 small scale kit. None are identical. I have plumped for the copies of the "works" plans. The problems with plans are that they are two dimensional. Building a box is simple from a 2d plan, but this is a wedge of cheese with numerous angles.
I then find that three different manufacturers built the same designated vehicle, all with minor differences. The one I had initially settled on was by the manufacturer who made the least numbers. So I go for the middle one.
Who says the Grmans are efficient ? And Mr. Bradford, once again your plans are junk :-(
Anyway, it is drying now, whilst I work out the optimum trajectory for throwing it, just in case.
