Recently I built a 4x4 Technic Jeep Wrangler.
It is built with two NXT engines, NXT CPU Brick, classic liftarms and custom shock absorbers.
Front engine is for direction, rear engine deserves transmission. Double transmission from rear engine to front bridge.
Has 81 wheels, transmission demultiplication to wheel 1:8.33, and weight 1.5Kg.
Due to fixed bridges to body, I designed individual suspensions on each wheel.
Great shape and those big black balloon tyres really suit it! You should upload a few outside photos of it tackling the wilderness! By the way, the chassis looks very tough and well-constructed! Looking forward to more creations from you!
