I was trying to work out how to fit the motors/electronics/batteries into a very small space and rechecked my scale plans to find I hadn't built the chassis quite deep enough. Also I have a possible buyer later for my static model, so I decided to start again from scratch and build it in the same way as the normal tank models. I am going to build a working chassis, and then build a separate mountable body to go on top, that way I can always get at the working bits without fighting the body parts in a very confined space.
Anyway here are the blueprints

The biggest problem with this model is the undercarraige, and scratch building in styrene just doesn't cut it for working components like wheels and suspension (I know this because I made the first set for the static model and frankly they look ok for display but they are unsuitable for a working tank). Anyway after getting a recommendation from Woz to look at Openscad I downloaded it and after a few false starts I created the suspension parts and wheels (with help on the wheels from Woz) and Woz will be printing me a full wheel and suspension set. Woz also has the scad for the driving sprocket and the track links I think, so anyone wanting to have a bash at building one can contact Woz and cross his palm with the appropriate amount of readies. I am going to use the track from the Tamiya wheel and track set (as I did with the static build) until I can find a proper set but I should be able to get the thing working with the temporary set.
Anyway waiting with bated breath for the components to arrive from Woz so I can get started.
