There aren't to many manufactures out there that only focus on race kits (xray is one of the only ones I can think of). Losi are still winning all the major racers and have the best line of racing kits out there (1/10 scale isn't as big as what it was years ago and there is no need to redesign their kits as there is no problems with it). As with Castor bringing out the 1st 1/8 buggy, get over it, no slipper kit installed just looks like a nitro buggy with a conversion kit
There is hundreds of 8IGHT-E's (the ones sold from Losi) out there, how many Casters is there? Oh that's right, there not out yet
