I am thinking of selling my brushed 19t setup and buying a 10.5.Are there any disadvantages or is it all positives?
Are they faster than a brushed system or about the same.I currently run a hara 2.2 and checkpoint 19t.

Aid,

Most people like running the drag brake in the 10-15% range.

Depending on what version of the GTB you have will determine how many "flashes" of drag brake (blue and amber LEDs) you need to be in that range.

The original/older GTBs this is 2 or 3 flashes.

In the 4 cell and newer li-po enabled ESCS this will be 4-6 flashes.

Damo,

There really aren't any major disadvantages to running brushless stuff as opposed to brushed. The system as a whole tends to be a little heavier than their brushed counter-parts... but usually you don't see a big difference from this on the track.

What you do gain of course is better efficiency, usually more bottom end response, MUCH less maintenance, and consistancy from run to run

The only smaller/low profile heatsink that is offered is the one that comes on the 4 cell version of the ESC...but it's intended for just that ...4 cell applications like oval or 1/12!

Steve Weiss,

What kind of Kv do you think a 25.5 b/l motor would come out to?

I'm guessing close to 2000Kv?

I don't have everything in front of me and I will have to double check on all of that later to be sure.

Aid: It depends on what the internal drive ratio of your car is... I don't know what car you are driving
Steve, I drive a CRC 3.2R AND GEN X.
THANKS

Steve:

What is the best way of teching these motors? I asked one of our local race organizers if he's interested in opening a 10.5r spec class and he's hestitant on how to go about checking to make sure that the motors are not tampered. Does Novak have any solution / equipment commercially availabe for doing this?

Default 10.5 on VeloDrome

Just curios how close the gearing is on a 10.5 when compared to a brushed 19t. We are running at the velodrome in Indianapolis. I used to run around a 78/45. How close do you think it should be the that?
