Mamba Monster Vs. Novak Hv Pro

[hemiblas]

I am a big castle fan, but the novak HV is not looking to bad. With my mtroniks 7XL feigao combo I can only get 37 mph but insane torque. The 7XL is too much for the mtroniks truck esc and it fried it. So until I get my MMM I am dead in the water. Even if I get my MMM doesnt the 7XL heat up a bunch?? The novak motor also looks pretty long which means it should have good torque. After seeing what the 7XL can do I really dont want to go backward in terms of speed and torque.
Also wont the Novak be more efficient than my 7XL which will mean longer runtimes?
