There are 00's of kits still out there (even the hornet is still available new)
Tamiya do a range of XB kits that are RTR but they are just their normal range of kits supplied pre built and painted.
The Hornet and it's stable mate the Grasshopper are real gamechangers in the RC car world, as they were cheap(ish) to buy and simple to build and maintain while giving pretty good performance.
I think most people who were into RC at a certain time had one.
