The Cobra is beautiful. I bought it with the intent of swapping in a Mini-Z chassis, rather than just playing with it as a "First Mini-Z". The swap is not just a plug-and-play, but will entail moving the side mounts (fortunately just hot-glued it) and careful fitting for a MA-020 swap. A MR-03 RM might fit if the rear shock is removed and replaced with a friction damper. Even so, this might be better as a parade car rather than a racer, as the jack points and side windows look quite fragile.
I am looking forward to getting into Mini Z racing. I would like to explore options to introduce engineering concepts using car and track design. I also want to leverage 3D chassis design.
