I have an Mi4 (non-LP) and it's awesome. Has TIR screws, rear driveshafts and layshaft and is awesome. Bought it set-up for outdoors, but run indoors and it's awesome. Handles really nicely, yet hasn't been on a set-up station since I bought it in december. Very tough car aswell, I'm running the carbon wishbones, and haven't broken a wishbone, c-hub or steering block yet
