Boiling nylon parts relieves the manufacturing stress in them and makes some plastics a little bit more pliable (flexy) especially in cold weather. However some Yok bits in the past have been known to MELT in hot water, but thats going back a long way.
SD comes with carbon-reinforced plastic bits, boiling shouldn't be necessary.
Brushless is good because of minimal maintenance required. Lots of torque, Novak is user-friendly & well-designed.
But a "good" 10t that's been tuned & geared correctly will easily beat the Novak SS5800.
