Got this car for X-mas. Built it up with an 1800kv HW Fusion motor (FOC off) with a large spur gear and LOVE, LOVE, LOVE this car. Completely silent, able to crawl up a jump, but also able to do 40mph and jump like a champ. Have also built it up with a Castle Mamba X and 1406 3800kv motor on a small spur gear. The motors are so different. The castle is set to be extremely twitchy - so it will go crazy with minimal input. But, if you dial that way, way, way back then you have a lovely motor esc combo that behaves incredibly on the road. The car is incredibly well built, the suspension is plush, everything seems durable so far and I will likely buy a second one. Can't recommend a vehicle more highly. Mind you - it did arrive with a dead light on the front... Croboll...???
