I have it here for about 2 weeks. For its price, there is simply nothing similar. Programming capability, support from 2s up to 4s (Mine came with an XT90 connector, so if yours comes with the same, make sure to have the same connector on the battery as well, because if you use different ones, you lose the warranty), a fan for the most demanding users, and support for motors up to 6000kv (with a 2s lipo). I got it to replace an old Castle Creations Mamba Max from 2008 (which I burned... awesome ESC as well) that I had in my old Kyosho Lazer zx5 SP (1/10). It should be noted that I combined it with a Castle Creations Mamba CM36s 7700kv motor that I had purchased together with the Mamba. I asked Hobbywing themselves if it can handle it and they said I wouldn't have any issues, and that's exactly what happened. It's easy to set up for the first time. It runs smoothly, doesn't overheat, and provides incredible speeds (I even saw a positive difference of 10-15km/h in speed compared to my old setup). If I encounter any issues, I will update. Get it with your eyes closed.
