I'm looking for a 92T 64P spur gear so that I can get an FDR of 4.0 to 4.2 for club 17.5 blinky class. What brand is everyone using? Spec-R sell their own but don't offer anything that small.

So was the maiden run made with the car

i had my doubts after building the car last night..

this was on a med size carpet track with low/med traction, using sorex28 tires and 17.5 boost

started with jeffs setup (exept 5 droop in the rear) and the car was really nice to drive right from the start!

after a few packs i attached the 4 screws in the topdeck over the layshaft just to get rid of some rear traction also changed to 2000cst oil in the diff

tried some spring setups, started with the std springs, felt really good, changed to tamiya white/blue combo, car was a little better, easier to drive.. then last i tried yokomo pink/blue and the car was perfect! fast rotation and good traction

really looking forward to try more things on this car!

i personally use kimbrough gears but also can use RW gears. Adrian M posted a link a few pages back showing the RW racing which is a 1 piece spur pulley combo which would result in the most concentric setup .

That's the 100T spur/pully assemby designed for the Photon. I can't find the part number though.

Xray makes a 92t 64p gear. Very nice round and tough.

Like the costumer service at spec r! Got a odd steeringpost and One of the upper bulkheads was badly scratched, they are sending replacements to me today. Very fast response

The Xray spur gears have the large access hole to reach the motor mount bolts, but they do not have the proper holes to mount the pulleys.

Wow, that's an odd request... If anything I had to dial the steering down a ton, mine had so much on power steering the rear would come around.

Did you follow Jeff's basic setup sheet? If so you should have a metric ton of steering. If not, it's a good place to start.

Also check out the xray setup guide.. gives you lots of options to get on power steering.

Generally droop, to be more precise front droop.
Adding more droop will keep the wheels in contact with the ground
longer, if that's still not enought then move the wheel base shims to the front of the arm... those are quick

there are literally tons of thing you can do....

As suggested have a once over at that Xray manual.

I find less front droop improves on power steering. It keeps the weight from transferring to the rear.

On power steering has a lot to do with rear suspension setup. You need to get the rear free and rotating so it follows the front on power.

What he said but what I really like is that this car has a 3rd motor mount hole for use with smaller spurs....Really Hudy himself might copy this
