I noticed this too when I used the mamba max systems. I let other people drive my buggy, and each and every one of them thought the throttle felt 'laggy'. I didn't notice this in brushed mode, only brushless mode. I would hear a bit of a squealing and then all of the sudden, the thing would take off. I hated this about the mamba actually, it just felt very inconsistent because of this lag, and then the sudden power. It would make the buggy spin out. This lag is also noticeable coming out of turns.
