Munar Probes: help me design mine!

[jebster]

I'm using the kethane mod, and I've got my kethane miner successfully to the Mun's surface along with two rovers. These rovers (which I call fuel puppies) transport fuel and kethane between my crafts. Here is a panoramic picture of them

They do their job but they suck at it! If they go above 8 m/s, they're likely to flip and explode. They can't stop unless they're on perfectly flat ground and I'm constantly quicksaving a loading because they're constantly exploding. Can anyone help me design a better rover that can go faster and explode less? Thanks!

Got better screenshots of it? Maybe in the light, or in the SPH?

Otherwise, I suggest using the Ruggedised wheels instead of those ones.

Wider and longer wheelbase, lower center of mass and ground clearance, disable steering on the rear wheels. Drive in docking mode. That's standard for rovers of all kinds, really.

Otherwise, m/s is METERS PER SECOND. Eight meters a second. That's about 20MPH, in 1/6 G. Maybe just don't go above 8 m/s if it flips and explodes at higher speeds.

On the Mun, light or top-heavy rovers will flip easily. To keep them from flipping forwards you need to add weight to the back of the rover to act as a counter balance.

I have a rover that weighs 1.02 tons, it was originally under one ton (marvel of a design, love it) but to counter balance it I had to add a battery pack and RTG to the back as a weight.

It also helps if you have a wide base, so that the center of gravity has to move further (it has to lean more) for it to tip.
