XRAY - Model racing cars

http://www.neobuggy.net/modules/news/
The first new part from XRAY is a 38 tooth front diff bevel gear. This makes the car easier to drive, especially in bumpy conditions, and improves on-power stability, traction and reduces sliding.


Has anyone tried these new gears? Will it require both front and rear replacement or only the front? Will differential set ups be affected?


Thanks in advance,

If you replace both of the gears it makes any kind of overdrive impossible to attain... Run it in the front so the front diff will be overdriven (front diff spinning faster than the rear diff with a 1:1 ratio of power distribution from the center diff).

As far as the diff setups go, if anything I would go up in the middle to 'intensify' the effect of the overdrive gear.

Most of us ran them at the New Zealand Nationals last weekend. The car pulls out of the corners better and is definately worth trying.

I found it to be a great help in stability, a little more push in center of corner straightened my frt shocks up 1 hole from before helped the push.As Rocco stated up center diff 1000 cps worked for me.
diff s before OD 4-2-3
with OD 3-3-5 found I was planted and stable with 5 in rear.Before OD could not get car to rotate in corner with anymore than 3000.The 5000 I run now may also made center push a bit worse but runs nice now.
In closing best atvantage I found, I could accelerate much quicker at corner exit and stay straight!! a lot less wiggle at corner to straight way transitions. hope its helpfull
