Well a short quick up date
This is what I am building in the right colours.
The main effort has been designing parts.
This is the final drive unit. Possed a big head ache. But got in the end. Will require learning/making internal gear rings. And nope can't buy what I need, I've looked. Lol but if any one finds a 31mm ish dia and 15mm deep with a 0.5 mod then let me know other wise tips on making one would be awesome.
The under carriage has been redesigned and so has the boom since getting the model.
