I wish NOVAK can offer the "replacement" program for those who purchased the brushless motor prior then the new "R" version that came with the sintered rotor.......like send in the old black rotor and get the sintered one for 1/2 price like $12.50 instead of buying the sintered rotor for $30 and having the stock black one as a paper weight....
Charlie....are you listening...? (LOL...just want to give that a try...I have 2 13.5 and 1 4.5 that are still using the old rotor and all get thermalled)
