The recent purchase from them.......a set of 3PK....4 days, with their typical EMS shipping...from HK to Chicago.
1 time, just buy a NTC3 carbon side brace from them....$20 US item, shippping is $3...........from HK to USA...took 5 days.

$3 international shipping within 5 days 5000 miles away(I think..).........you cannot even ship one pinion gear from Chicago to Indiana for $3 US

On my web site, I've given my customers the option to choose USPS First Class shipping which starts at around $2.73 for them. When they order 1 or 2 parts, they choose that shipping method most of the time too.

Yes...2 words, TRACTION ROLL

I am no expert, but have been told to use Parma foam, trued down to 59mm front and rear, or 60 rear 59 front.......then it will last you good 2 sunday racing...........

make sure CA the edge of the foams too.......

About the setting........way too many, someone here can help....I forgot my indoor setting, I am doing outdoor mod foam setting now.

why do you need so much rear toe-in?

rear toe in give you more rear traction under acceleration, but going more that 3 degrees i think it will make worse.

Brushless...Motor heatsink,On most of the new motors the heatsink wraps around the can and blocks the air flow from the armature increasing heat.
Pro 4 parts....USA www.speedtechrc.com
HK www.precisionrc.com
Both these sites have exellent service and heaps of parts including aftermarket parts...Tobe square etc

From all the brushless ppl that I know....none of them need to add heat sink onto their BL motor..........but they all have fan(s) to blow toward their ESC......plus vented hole on their body....

Seems like the thermo shut off are what they concern more then the motor itself, they said their motor rarely get extremely hot if you geared correctly.

yup.. esc overheating is the main concern. i drive with a fan on uforce on novak also, but even esc does not help for novak to hold 5 minutes when racing shut off 2 meters before finish line on last lap

I think Barger is right here that motor heatsinks only work if they are not blocking the vents for the motor, if they block the vents then they stop all the warm air getting out and the cool air getting in.

the Eagle/Integy heatsink is vented to allow air to pass through.

I used this on my 8T V2 motor running outdoor with track condition can be over 90 degrees sometimes. yes, it does look like a geek, like a rookie..........but it does work.

I filed a channel under the chassis to improve airflow to the motor.

Default Question

Is there any reason why I couldnt use my .5 degree rear hubs on the wrong sides to reduce rear tow in.

just seems easier and cheaper than buying new pivot blocks.

Thanks
