Watch Jason Quayle’s 1/12th scale remote control Alvis Stalwart drive on tarmac and take to the water. This is an extended video of a 1/12 scale Alvis Stalwart amphibious RC truck driving and sailing around Silverdale lake. The truck has been scratch built using a Tamiya 6 x 6 donor chassis. The chassis has been modified to shorten the wheelbase, convert the middle wheels to steer and has had 2 x 12 volt water pumps added to provide water jet propulsion on the water. The model also features a working crane, swim board which deploys when entering the water, a smoke generator and sound unit. Enjoy!
