First R/C build: Cat 6015B 1:14 scale

[Jon Auty]

Hello all, ive been contemplating building a 1:14 scale excavator for some time , and its finally happening due to a change in work commitments. Being a fan of the big cats i have chosen a 6015B for my project. This is the new version of the 6015, but is more similar to the old cat 5110B in shape and build.

With no machine to go from ive printed the pictures from the Cat specalog in the correct scale and started drawing up models to suit. Its going to be BIG! 4.5 inch flap wheel to give you an idea on size

The bucket side was a quick drawing and 3d printed to compare to the specalog to confirm the modelling was at the correct scale, all found to be ok so on with the tracks. The 6015B uses the same pitch chains as a D11, so a few measurements and a pad and link assembly was drawn up and printed and assembled for fit. This was then followed by a double grouser pad which is correct for this style of excavator
