This project was inspired from Daniel Noree's OPEN RC project and is an adaptation from FFORMIWLA 3D PROJECT NANTGAREDIG.
The truck is fully remote control enabled. The design allows for suspension with a pivot system and soft tyres. The truck can drive over obstacles while retaining a simple drive (ie not a 4x4). The body is strengthened to withstand collisions but not very heavy. It can drive fast depending on motor rating. It can be used in an uneven terrain but not fully off road (a longer axle adaptation is required). The assembly is simple and quick requiring mainly cable ties. This would make an ideal educational project or a race event, and will attract the interest from young learners and their teachers, targeting all ages starting from primary school age groups.
