Hi guys I've just been given a rc nitro truggy and the lad said it's a "kyosho ultima st roller" is this a model because I'm not sure? please help thanks

The Kyosho Ultima ST is a Stadium Truck. Roller means that it needs supporting equipment in order to drive it. Do we know what generation Ultima ST that it is? There was a Type R, Type R Evolution, Sports (RTR), ... and maybe a few more that I missed. I had a Type R, absolutely loved it. Sadly, the nitro ST class is dead.
