The question is why is the Xray the opposite of these? More droop in the front and less in the rear. Instead of less droop in the front and more droop in the rear?

Can't argue with the way the car works this way, just curious as to why this is.

Later,
1) height of hinge pin mounts
2) there's a differance in shap and size of spindles/carriers and rear hubs

u cant really go off the gauge.
traction, size of tires, everything changes to change droop. u need to measure the amount of it from front and rear, i usually start with 2 mm all around for droop as a safe point

Default Droop Question

I am not cocerned with how you measure droop as much as I am in why with a TC3 you have for example 6 front 4 rear, then with the Xray you have 2 front and 6 rear. Why is it reversed when compared to a TC3 or a XXX-S?

Later,
Here let me define this further;

Some manufactures go by measuring off the bottom screw that holds in the front carrier with the overall spindle being a differant size not to mention that it can be higher or lower in the arm while others mearsure off the arm, spindle or carrier alone. That applies to both front and rear.

Default Mounting Fan #1

i cut a small piece of carbon mounting plate from scrap chassis and shoe goo the fan into the plate. I also goo'ed a 3mm lock nut into the plate so that it would be easier mounting and unmounting the fan. I also used a set of servo plugs so i can easily detach the fan when needed.

Default Mounting Fan #2

No additional drilling on the chassis. I used the pre-drilled hole for the tranponder holder. You can also swivel the fan to any angle you want.

Default Mounting Fan#3

The mounting plate was cut with an offset hole so that there's enough space for those schottky diodes. i also use spacer washer between the mounting plate and the chassis so the fan mounting plate would not leave any "footprint" by grinding dirt in between - due to vibration when running.

Nice pics stik. That's definitely easier than what I had to do.

thanks RCI! the pic did turn out better than expected since i had my white balance set wrongly.

I'm hoping XRAY or someone else could come up with a molded one with a nut recess (something like the XRAY rear composite bumper). With the time and effort i put into that, i'd be willing to pay for one. I could also imagine it working with any carbon plate chassis.

Default Droop

Many of the manufacturer's are measuring their droop at different positions. If you choose to measure your droop this way you can measure out to the "ARM". Do not use the screws or boss', etc.. This will give the same measurement car to car.

A great way to measure droop is by up travel. Set your ride height in all 4 corner at say 4mm. Then hold the wheels on the ground and lift up on the front shock tower and remeasure the ride height. If it shows 6mm ride height you have 2mm of up travel. I find measuring by up travel a great way to set droop.

What is that black thing on the cable? Is it a schottky diode?

That's the new diode for the GT7 I believe.

When you guys installed your low ratio pullies, did you end up going down on the pinion from your original gearing before the new pullies. Because I burned up a motor last night and I could never get the car geared right. It was stock with rubber tires, btw.

Another question my mod foam last night was very fast, but when I would sauce my tires the car would traction roll for the first half of the race. Otherwise the car handled great. I did notice that my ride height was very high inconjuction with new tall foams. This would most likely be the problem correct?
