What do you want to know about it?
4mm chassis standard, direct steering system, 3 belt drive, front and rear gear diffs (front one-way is available), universals all around.
I currently use it as a spare car, which reminds me that I need to put it back together
. Handles pretty good, the suspension geometry on this car is just as good as the current set of cars on market. It is not quite as adjustable though, no changing front roll center, changing of the rear lower arm to change the rear roll center, or steering ackerman (you can mod this though). If put side by side with a MTX3 you would barely tell the difference (besides the direct steering system).
The only reason why I'm running the MTX3 Prospec now is because of the availability of GS parts (GS decided to distribute their own products) was lacking and it didn't appear that I could get parts for it anymore. Fortuneatly/unfortuneatly Horizon Hobby will be carring parts once again.
