I will leave my personal opinions out of it because nobody that likes Novak wants to hear it anyway.
BUT, any motor that needs to have the whole thing replaced just because the motor sensor wire is bad is crap. Buy a $75 motor to fix a $5 wire???

I've had and seen many Novaks go up in smoke. Including one that burned an Ofna LX Brushless conversion to the ground.
I was offered a "refurbished" POS for 1/2 the cost of buying a brand new one.

I've seen only 1 Castle ESC go up in smoke. The first batch of the V3s that came out last year. Running 6S in a Revo on an indoor track.

Belonged to a good buddy. He called Castle understandably pissed. They had a brand new one (NOT REFURBISHED) to his front door 48 hours later on just his word that he would send the burnt one back. When it arrived he hadn't even pulled the burnt one out of the Revo yet. Anyone have a story of Novak doing something even close?
