If your on an incline and take your finger off the throttle, the rotor doesn't hold it's position. Instead the rig will just roll off the rock or whatever. It doesn't lock and hold it's position. On brushed motors it holds it's spot, but with the Novak's it just rolls off.

I switched to Mamba Max ESC's now and because of the programming possibilities I can set the drag brake to 0% to 100%. It's awesome!
