Just received in the Wotan archive is this snappy blue Stomper Quad Climber vehicle. A rare addition to the Stomper Megastar line, it has double articulated tracks and two gears for extra climbing traction. Schaper Stomper vehicles were big in the eighties as small, powerful electric motors became available and the line was immediately successful, including all manner of 4x4 trucks, cars and tanks. My personal favourites were the space themed megastar line which included a small 2 cm jointed figure in each vehicle.
The green crawler vehicle below always reminded me of the Spacex MEV and I had to add a couple of Diaclone rocket launchers to the side of it to pimp it up a bit as it became my favourite. The tiny green figure arrived in two of the four vehicles whilst the other two featured a small silver chap, not unlike the original (and contemporary Cylons).
Each vehicle had an action feature, like the grab, battering ram on the yellow one, laser cannon on the white or the removable drone robot on the camouflaged truck.
Before Megastar came Water Demons, a line of amphibious trucks on large float wheels. The lime green one had a rubber boat on the back and the army version has rotating missiles. Last but not least we have a Centurion Tank Stomper, one of the earliest models.
