Ive converted all my cars to HobbyWing. HW has something for almost every class and their prices are perfect. $50 for a Justock is unbeatable. Novak has been around for a long time and I they make some great hardware but you're paying for the name. Hopefully HW's head wont get bloated from the mass popularity and they wont jack up their prices and I will always be a customer. Also, I don't know if this is directly related to the speedo or not but after I switches over to the HW ESC, my motor ran about 6 degrees cooler on average.
