Would like to hear some feeback on the Novak XBR system, interested in the 8.5.

I have Integy 3800 nimh, wondering what runtime I can expect in a B4.

Thanks

I cant tell you what your runtimes will be. But I can tell you that I get around 15-20 minutes on my Reedy II 3700mah batteries in my 4WD DF02.

The XBR/EX 8.5 is not as fast as the MM5700. But it is plenty smooth and has good power.

If you are in the market for an cheap, reliable ENTRY level BL setup then I can reccomend the Novak with confidence. Just keep in mind that there are faster more powerfull motors out there.

i have ran my XBR 8.5 briefly and i like it, typical Novak smoothness and with more speed than i predicted, sure, if you want crazy speed, go with the MM 5700.

BINFORD

Thanks for the info,
I had the Mamba Max 4600 and 5700, but I want less power for bashing and more run time would be nice.

I also like the fact that the bearings and rotor are available sepparate, and I've always been happy with Novak in the past.

The Mamba was good, had to send in a motor for noisy bearings, sent me a new one no questions asked, but would rather have more runtime and less power.

Are the brushed ratings accurate or are they faster than that?

i bought the XBR for the same reason, i needed less power, but smooth power, as my RC is RWD, seems to work good so far, and i havent played with the settings yet..

Phelansa

Seems the common consensus then. I had a MM5700 in the DF02 and it was just to much power. That is why I bought the Novak.

I would say that the Turn ratings that Novak give for the XBR systems are pretty conservative.

Pretty happy with the system so far.

I'm thinking maybe the 10.5 might be better.
My favorite motor was a 15T Speedgem as far as power level

I couldnt be happier with my XBR 8.5. Good power and good run times. Smooth as butter....

BINFORD

What runtimes are you getting, what battery,which car?

Thanks

Phelansa

20-25 minutes depending on how hard I am driving the car. Tamiya DF02 with a Hyperion 3300mah 2S Lipo battery.

15-20 minutes on a 3700mah Reedy Power II NiMh.

My final drive ratio is just a tad over 10:1

BINFORD

Thanks Phelansa, that sounds more like it.
I was getting 6 min with a Mamba Max 5700 in a T4 12.57:1 gearing on the track with Reedy X-Rated 3700 nimh, and 8 min with Integy 3800 nimh.

[X(] I would throw that MM out the window (or into ebay) if I was only pulling out 6 minutes. Or i'd cry, whichever came first. Thats why The way I see it, if you want to use NiXX, use a novak.

Already Sold Both Motors and the ESC on Ebay

I think for a truck you may have been geared a little high with the 5700. I mean if you ran a higher ratio (15:1 or similar) it might have run better. I guess if it was geared up too much 12:1 it may have been pulling too many amps and therefore you got less runtimes...But then I wasn't there so who knows.
