Novak XBR 13.5 System pro/cons?

[Ken448]

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!
Ken
