I have tried almost every Mini-Z related chassis currently avialable and I can honestly say stear clear of the IDT and IMT. I own both along with multiple MRX and have made my own aftermarket chassis and can say with confidence that spending money on the IDT / IMT is a mistake. Stick with an MR-03, and MRX, or an 020 if you want AWD. Anything else is overcomplicated and poorly excecuted.
