What budget have you got for it?

I converted a 1:8 scale nitro car to brushless. I recently replaced that system for this:


A Trackstar 150A ESC and 2650kv motor, with a programming card. (Ignore the battteries, they are for a feather). The whole set costs about 100 euro. All I needed besides that was a brushless motor mount for it and a battery tray.
