Novak XBR 13.5 System pro/cons?
 

I am looking for people that own this system and have run it against Novaks GTB 13.5 system. Is there a definitive diffrence?

I am setting up a Staduim truck to run indoors. This one will be for stock class only (allow's 13.5 BL motors) My mod truck has a Mamba Max 5700 in it.

If you have the XBR system, do you like it? Would you buy another one? Why? Does it perform the same as a GTB 13.5 system??

Thanks!

There is a significant difference for both features and specifications between the GTB and XBR escs and the SS13.5 Pro and 13.5 EX motors.

If you are racing, and the rules allow sintered rotors, use the SS13.5 Pro motor. The EX motors have bonded rotors and are not recommended for racing. Some local race directors do not allow sintered rotors, so we still offer bonded motors for those situations.

When racing a 13.5T motor, either esc will perform fine. The GTB is the top racing controller so is more versatile if you want to run a hotter (fewer winds) motor in the future.

Opinions vary... I think there is a difference but it's not huge. The XBR system has the regular bonded rotor 13.5 so it will likely run a little hotter and not have quite as much punch.

I don't run them, but a lot of my buddies do. The guys running the regular 13.5 (XBR) do just fine on the track and you can't tell any difference just watching. I don't know how much of it is in their heads... but some say the 13.5 pro is faster.

Maybe it matters in certain situations like on road or oval... but for offroad I can't see how it's a big deal. It's all about driving.

I thought the 13.5 EX could use a sintered rotor as an upgrade? Is that not correct??

Correct.

You might need to buy the sintered upgrade kit that comes with a new larger bearing/endbell.

That would basicly make the Ex into a Pro
