It is either a Himoto Syclone or Python. This is their page for the nitro buggies:

The truck is either a Himoto Eldorada, or a Viper. I can't really tell if it has plastic or aluminum arms, which is the difference between the two trucks. Here is the page for the trucks:

Most US sources for Himoto parts dried up a couple years ago.. The only way i know of to actually bring them back to life without spending months waiting on parts from China, if they are even available, is to source Redcat, HSP, or Exceed nitro or electric pro complete chassis, and swap parts around until you have a running vehicle. If you do it that way, as long as they are the pro version, even the electric cars can be used for parts, since the electric Pro versions and nitro versions of Redcat and Exceed stuff are all the same parts. To do it that way though, you need pretty much everything except the chassis from the Redcat and Exceed cars. Sometimes though, you can pick up used Redcat pro vehicles on eBay for around $50-$75, and you can get brand new pro versions of the Volcano and Tornado for between a $100 and $125. Another way to do it would be to pick up Redcat nitro sliders or rollers, and just drop your engine into that car. I dont know of any other vehicle that will work for parts for the Himoto stuff, unfortunately. I have 3 Himoto based (Horizon Hobby's discontinued Force RC trucks were just rebranded Himoto Bowie's) electric trucks that need parts, so they have been sitting in a box for months because i can't find parts anywhere.
