Yes, light would give it the final touch, but its quite hard to fit them in without screwing the design...

Yes, your right with the point that the model will not perform well in snow, but I didn't build it for that purpose. I really like the Idea to squeeze many functions into small space and use some sort of mechanism to have more RC functions than motors.
I originally planned to make the model bigger and with XL-motors without being related to an official lego model, but as I started building the gearbox, I realized that it would fit into the 8263 if I use M-motors

Thank you for your comment. I am currently planning some other attachments. I'm thinking about some sort of claw arm and a bridge launcher
