I may actually pull this rabbit out of the hat.
The AFV Club Nashorn Suspension is designed to be workable and very difficult to mount. Completed bogie trucks are fragile, even when frozen with cement. AFV Club axles are too skinny to fit Dragon road wheels so all balancing was done with AFV Club road wheels. Getting all road wheels to sit on the ground in a straight line while also keeping all mounting bosses square with the hull was horrible.
I will give this a couple days to dry, then pull off the road wheels and hope nothing breaks. Fitting the already built up tracks will comprise the next major hurdle.
