Very good motor and very fast. Smooth operating motor. I'm very pleased with Viper quality. There is one thing I should point out though. Be very careful with soldering your motor. The posts for the wires are narrow and recessed. Doesn't allow for a lot of solder and the tabs can be problematic. One of my wires came loose and it migrated over to another post. The recessed tabs made it easy for the loose wire to slide in and stay there. Burnt up my ESC. So, be careful and make sure your wires are properly soldered. That's not enough for me to dissuade others from buying it.)
