2 questions....

(1) stock brushless 13.5........does that come with the front big bearing /end bell replacement and the Sintered rotor like those who were talking about at the other novak stock brushless motor thread..? They were saying something like need to call/email Novak and get the upgrade/update...very confusing.

(2) Already got the 4.5 motor........and I saw tower has the 3.5R sintered rotor and said it is an upgraded rotor for the Velociti 4.5R or 5.5R......so, is that the only parts that need to convert from 4.5 to 3.5 or the actual 3.5R motor has more then just the rotor different then the 4.5..? I am just debating should I buy the whole 3.5 motor (sell the 4.5) or spend $30 to get the 4.5 upgrade to 3.5 and use the 4.5 rotor for spare...?

Thanks in advance...........can't wait to be full brushless.
