Which HV are you getting, the 4.5 or 6.5? The 4.5 is 4,800 kv, the 6.5 is 3,100. Assuming 1V/cell under load that would be:

7V*4,800=33,600rpm, 7V*3,100=21,700rpm

The 4.5 would be a better choice for 7 cells. Definitely better than stock. Depending on the weight of your truck, it will be really quick. The Novak systems are sensored which gives them zero cogging along with great torque at any speed. Running on 4s LiPo I could still pull wheelies from a stop with the small HPI tires, nevermind my Masher 2ks.
