The model was difficult to make. Access for fixing nuts and bolts was at times very difficult. The manual construction order is not very good. I had to part dismantle it sometimes. Also the diagrams were often not very clear as to what goes where.
The operation is reasonable, with an E15R motor running continuously, and carrying out two tasks of driving the vehicle and lifting and lowering the winch. The shovel release mechanism is very clever. The E15R strains and needs to be run at 13½V DC.
