Default TLR 8ight-e rtr diff questions

so I just received my new tlr 8ight-e . I was looking in the manual and it doesnít show anything for differential maintenance or even how to dissasemble them to change the oil and so on. My question is , is it necessary to change the oil or just run the thing? How long does whatís in there last? And what oil should I run in each differential? Thanks sorry for so many questions still new to this.

Diff oil on the RTR's are usually in line with their race kit counterparts.

Try 5/7/3 and play from there depending on track conditions.

Replacing diff oils is usually a good idea after a race weekend (qualifiers, mains, etc). Some do it after qualifying so they're fresh for the mains and others do it way less often. Really personal preference. I replace them after a race weekend.

If Iím not a racer then how often. And by 5-7-3 do you mean 5000,7000,3000?

You can adjust the characteristics of the differentials by using thinner or thicker silicone
oil within their cases.
• Changing the oil in the front differential affects overall steering response.
• Changing the oil in the center differential affects the front-to-rear drive.
• Changing the oil in the rear differential affects cornering traction and overall steering.

EFFECTS OF DIFFERENTIAL OIL REPLACEMENT
DIFF OIL
THICKNESS CHARACTERISTICS
Front
Thinner
• Increases steering into corners (off-power)
• If oil is too thin the steering may become inconsistent,
especially it can lose forward traction (and steering)
during acceleration out of corners
Thicker • Increases stability into corners during braking
• Increases steering on-power at corner exit

Center
Thinner
• Front wheels unload more during acceleration
• Decreases on-power steering (reduces oversteer)
• Easier to drive on rough tracks
• If a high-power engine is used you could waste too
much power and sometime “cook” the oil in the center
differential because it “overloads”
• More off-power steering
Thicker
• More all-wheel drive effect
• Better acceleration
• Increases on-power steering (reduces understeer)
• Better suited on high-bite, smooth tracks
• Car can be more nervous to drive especially if a high
power engine is used - you might need to be smooth on
the throttle

Rear
Thinner • Increases cornering traction
• Increases steering into corner
Thicker
• Decreases rear traction while cornering
• Reduces wheelspin

Hope that helps!

Did you mean 5000,7000,3000 when you said 5/7/3

Personal preference. If you bash a lot, then do it every time you tear the car down to do a full clean. If they feel gritty, change the oil (but also check the gears too, gritty can be either of the 2).
