Hi All,

I am thinking of racing into 1/12 on-road. What is the difference between the two motor/speedo combo.

Novak GTB/SS 10.5 Pro Brushless System
&
Novak XBR Sport/EX 10.5 Brushless System

Is the Pro system worth the extra 90 bucks? What is the performance difference between the two system? As much information on the two systems would be appreciated.

Thanks..

First you need to clarify.. GTB (Racing) SS PRO or GTB 4 cell version??

If its the Racing one with the fan then.. the GTB SS has half the resistance, handles nearly 4x the power, is more adjustable than the XBR and weighs less also. the XBR will handle down to an 8.5 according to the chart below. since you are putting this into a 12th scale you might want to ask around if the XBR is small enough to fit under the body. I don't think the GTB is due to the fan.

if you are referring to the 4cell version.. it has the same specs as the big brother version but does not support lipo and with that difference comes less weight again.

Hey dude, got some specs here for ya....

The biggest differences are: GTB ESC is slightly smaller than the SS, but the SS can handle 7 cell batteries. The GTB has a motor limit of 3.5Turns while the SS can only handle an 8.5 turn and up. Here's Novak's data chart.

The differences are not imporant the 4cell GTB is the only one(of the group you've asked about) that will fit under 1/12 racing shells. So thats the one you want.

I believe that the XBR sport package uses a bonded rotor as opposed to GTB package using a sintered rotor.

I would not chooose the XBR for 1/12 for two reasons. May need a receiver pack for 4-cells, and istaller than the GTB 4-cell version. This means if you are racing the GT style bodies getting the ESC to fit will reqiure some body work or raised body.

For 1:12 I would either use a GTB 4-Cell or the LRP Sphere comp.
For motor choice, go with the 13.5 SS PRO, the XBR will need to be upgraded to be competitive and that just cost more money than doing it right the first time.

Could you please stop posting! I get as far on a thread as you post and your bloody avatar stops me getting any further. Besides that my neck is getting sore from nodding my head.

So, GTB is the way to go with 1/12th scale?
