In my eyes, it isn't a well thought out design. You'll notice that the suspension parts are leftovers from Kyosho's V-One Nitro Series or Trinity's Reflex. The roll centers are wrong. Look how high the rear up rights are. Not even tucked under the wheel. You'd expect the CG in this car to be base around a nitro engine. The pillow balls are probably carry overs as well. That would mean they weigh 20x more than normal hinge pins. I'm sure it's tough. If someone were to give it to me, I'd use on the half-pipe.
It was a good idea to sell a spec car. It's just the wrong design for one.
