When seen from above, if the forward facing part of the front wheels or the rear wheels on an RC point away from the car and away from each other their position is described as toe out... Although less stable than a toe in position on straightaways, front toe out may provide for more responsive steering on turns... Rear toe out is rarely used... Most RC guys be it drifters or tourings prefer to use front toe out...

When seen from above, if the forward facing part of the front wheels or the rear wheels on an RC point in toward the car and toward each other their position is described as toe in... A slight toe in angle is commonly used to provide stability but too much toe in creates friction that slows down the car... Front toe in can help on straightaways while rear toe in slows you down on the straightaways... But rear toe in can help counteract an oversteer condition making it useful on a curvy course...

1.5 Degree Suspension Arm Holder

Most RC cars kit comes with changeable suspension arm holder... I change mine to 1.5 degree for the rear to create more toe in... Before using this setting, my car tend to oversteer a lot making it harder to control... Now setting the rear to 1.5 degree toe in, my car is very balance... No more over or understeer...

Muchmore 25mm x 25mm

Muchmore 30mm x 30mm

There are two sizes to choose from... 25mm x 25mm and 30mm x 30mm... This fan is usually use for ESC... I am using 30mm x 30mm for my ESC because I accidentally broke my original ESC fan... Without a fan, the ESC will definitely overheat... Instead of getting those China brand, I opted for Muchmore cause it is a very reputable brand and the performance is really insane... The fan turns at a very high speed hence the name ultra high RPM... Now my ESC run much cooler and definitely won't overheat...

So whats the benefit of running better fan for my ESC and motor cooler posted in my previous post??? Longer runtime... I don't have to stop drifting halfway just because the ESC and motor is overheating...

My motor use to be very very hot... As you know, it will damage the motor if the temperature is too high... When using this motor cooler there is significant drop in temperature... Before using this motor cooler I tried using others, but they are not as good as this... Besides that, now I am able to run a wider range of gearing for my car... This is indeed a very good product... Now I am not scare of overheating my motor anymore...

Blue Anodized Aluminum Motor Mount For TA05IFS...

The benefit of using aluminum motor mount is you can save as much as 4g weight saving over normal motor mount... This is very important for touring but not so for drifting... Besides that, motor will run cooler due to cooling fin running along the motor mount... Last but not least, it makes your car looks nice... More bling...

Front One Way...

Just as described, the front wheels are only allowed to turn one way... A one way bearing in the diff prevents the tire from spinning backward... While on power, both front wheels get equal power (no differential action)... Off power, the front wheels free spin on their own accord... This give high initial turn in, and allows you to really pull through the exit of a turn, as both front wheels are applying maximum power to the ground... Breaking becomes an issue, as the nature of the one way does not allow breaking to effect the front wheels... In effect, its like yanking the e-brake on a car... With out proper attention, this causes the car to loop out much easier, and makes it twitchier at speed...

The benefit of front one way on RC drifting is to minimize understeer... When using front ball diff, more understeer will occur and it is very hard to drift in tight and S-turn corner... Besides that, the angle that the car make is not that beautiful... The downside of using front one way is the car is harder to drive... But once you master it, it is actually as easy to drive as a front ball diff... Most RC drifters prefer to use front one way over ball diff...

Rear Ball Diff...

So what is a ball diff??? It’s a clever little device that takes up the difference in rotating speed between the left and right side driven wheels... Unless a four-wheeled vehicle is traveling perfectly straight, its left and right side wheels travel on different paths, at different speeds... The diff compensates for this while providing drive force to propel the vehicle... Without a diff, one or both of the driven wheels would be dragged across the road surface, resulting in a loss of traction...

Difference Between One Way And Ball Diff...

This is the limited edition damper by Tamiya Racing Factory (TRF)... The damper shaft is coated with titanium nitride... The titanium nitride coating offers a much harder surface than the stock fluorine coated shafts improving the life of the shaft and increasing time between rebuilds... The titanium nitride surface is also very smooth providing an ultra smooth compression and rebound action...

TRF damper with aluminum damper retainer 1mm down type...

Because springs tend to vary in length, Tamiya now offers aluminum damper retainers featuring a spring support surface that is 1mm lower than standard... This provides much more flexibility with both Tamiya and aftermarket spring choices...

In order to prolong carbon parts, it is advise to apply a layer of CA glue to the edges... Besides that, it is even better to use a very fine sand paper to sand off the rough edges... The reason for all these is to minimize crack due to collision...
