Build 15 vehicles propelled by a hydropneumatic motor.
- Two different systems:
- 5 models with a motor using pressurized water – Ideal for inside use since this system keeps the water in.
- 8 models with a reaction motor using pressurized water – Ideal for outside use since this system releases water.
- Includes all parts required for assembly: water tanks, secure pump, nozzle, air-water power pack.
- Full colour 48-page instruction sheet with explanation of concept and models.
