Hi Guo,


For Kota Raja Speedway I would say start with this on your 7x1 V2 UL motor:

9 Degrees timing
Sprint Edge Brushes
MR - Med Hard Springs (one step below the stiffest)
Geared at a 8.5 FRD

If more top-end is needed gear up, if more bottom-end RIP is needed turn up the timing to 12-14 degrees (but only if runtime is not an issue, otherwise you will probably dump).... Hope this helps, look forward to meeting you next month...

Curtis,

Default Brush Alignment?

if the brushes are not aligned properly will there be a black mark on the trailing edge of the brush?

My brushes get that also, on the XXX ones. I think its caused by the little bit of arcing from not being perfectly seated. I haven't noticed it to cause any problems though. I break my motors in with XXX brushes at .7 volts for 4 minutes then 1.2 volt for 30 seconds. When I rebuild my motors each run I use a fiberglass comm brushes and clean the whole brush.

SPC: It's just caused by arching, low turn high RPM motors with stiffs springs and high timing will always get a build up of carbon on the trailing edge of the brush, this is considered to be the norm on square brush mod motors..... IF the brushes were out of alignment you can visually see this in the way the face of the brush has worn (viewed from the top of bottom of the brush)....

The same goes for stock and 19 turn motors as well.... The increased overlap provided by a laydown brush increases arching, so it is not uncommon to see a slight amount of carbon build up on the trailing edge of the brush face.... We've been narrowing the brush slightly by removing .015" off the trailing edge of the brush, this in turn reduces arching and heat buildup while at the same time providing slightly more torque....

Curtis Schlaht :

for the Kota Raja Speedway, would you recommend a single or double wind?

for a Ti3 8x1, should i go to around 8.1 to 8.2 FDR?

thanks -jason
