Build this fascinating tipper truck and see the power of pneumatics in action. Using syringes connected by plastic tubing the tipper truck can be made to lift and drop a load at will. Made from TechCard the truck is both easy to build and surprisingly rigid once made.

Harness the power of air with this easy to build TechCard model which can be made into a land yacht or balloon powered car. In the kit are all of the components including the TechCard (which is pre-cut and punched), card wheels, axles, card sail, dowelling mast, balloon, printed modelling sheets and decals.

300 x 200mm sheets. A pack of 40 sheets.

Jaws gnash as he marches forward eating everything in this path. Put a small object in his way and it's gone in a flash...don't stand too close! TechBot 1 has large drive wheels powered by an electric motor and a cam mechanism to power jaws.

TechBot 2 is on this way - stand clear as he shunts forwards lifting his huge feet as he does so, climbing over uneven surfaces and obstacles that get in his way. He has two mechanical feet connected to an electric motor by two rotating cams.
