i just received my 13mm rotor. the magnet strenght is huge. cant wait to test it out.

hopefully will give me the torque i get from the bonded rotor yet provide the lower temps from a sintered rotor.

p.s at novak. why not a 14mm rotor. i measured the bonded rotor and it measured around 14mm

I used it in the 13.5ss pro. At first I went down three teeth on the spur and I went up two teeth on pinion. Then backed down one tooth. Then back down to what I had been running. I ended the night with the same gearing I had previously. But when I got home I found a grenaded bearing on my left rear hub.
So I need to retract what I had to say about the 13mm rotor for now. I'll post back on Fri after refreshing things this week. LOL. Maybe I should have said it had soooo much power that it is toasting my bearings. JK.

According to Novak,, the 13mm is really for the hotter motors. Definately gear up and smoke em like a cheap cigar!

Yep, this must work better in the hotter motors. Oh well. I can still use it with my 7.5. Doesn't work too well with the stock brushless. Tonight the car lacked a lot on the track. I'm still somewhat new to racing. Started electric in February so my senses arent' up to par on noticing small differences like this.

The last two weeks I have been running the new 13mm rotor from Novak in my 13.5 powered Gen X. The motor feels very different than when it had the origonal, smaller rotor. It's not as punchy and doesn't have the same high strait-away speed, but it is a lot smoother across the throttle range and holds speed better in the infield. I don't think that the motor itself is faster or more powerful, but because of the difference in the way it acts, it makes me faster overall. I did have to gear up significantly to keep up in the strait. All in all I think it is a good tuning aide, worth investing in. I posted a new track record last night.

Yeah, I'd like to know how it does in the faster motors like the 7.5 and 6.5? I don't think I drive well enough to give a fair comparison. LOL. I should have tried it in my 7.5 tonight, but I didn't want to take a chance. LOL. Maybe next time.
