Well the blx 185 has failed my again while they will replace it free of charge im getting tired of sending the esc and motor in every few weeks to get it replaced im thinking about a mamba monster x or mamba monster 2. Would anyone recommend one over the other and why? I see there is a 40 dollar price difference and not sure what makes that price difference. i was considering the 2200kv for both of them they also offer a 2650kv what would you guys go with and why ?
