Guys, anyone here who can give me a link where I can find a
spur gear size from 78 to 80/48P for my 007 EU? I'm looking for
a direct fit to my Xray if possible without any modifications.
Thanks in advance guys!

I usually use 64 pitch but am going to be doing some parking lot running and want to use 48 pitch. Any suggestions for spur pinion combination that fits on the 007 to get a 3.5-3.7 fdr?

How can you tell if a diff needs to be rebuilt on a '007?

Iím a total RC newbie and a friend lent me a T2'007 to play around with. He mentioned the diff might need to be rebuilt but wasn't sure. From a dead stop, it doesn't feel like the initial acceleration is what it's supposed to be. There is a lot of noise and not a lot of reaction...
The acceleration is responsive and feels fine once the car is already moving.

I believe there is a multidiff in the front and the esc/motor is Mamba Sidewinder/5600kv

If anyone has some tips on what to check out I would appreciate it.

I would ditch the 64p and stick with 48p for all asphalt driving. I run 87 spur with a 20 pinion, I works good for 19T spec class at our track.

64 pitch works great for me on my normal track which is a prepared permanent track, but this is a blown off parking lot. That ratio gives a 7.4 fdr anyway and I need a 3.5-3.7 with brushless 17.5, that is why I was asking about fit with that ratio.I had been running 13.5 before. I wonder if Xray is working on a more Brushless friendly internal ratio for the next xray.

tarheel, they might be, but keep in mind that the T2 at 1.7 is the lowest internal ratio on the market (I'm pretty sure). I recommend a 72t spur, if you can find one.

Adamge,
I know it is which is what makes things so bad. We may have to go to a 1:1 internal to get things so we do not have to use these wagon wheel pinions. either that or redo adjustment slots a lot to allow for smaller spur gears. Thanks for the advice on spur I will try to find one.

It's certainly easier to move the battery screw slots closer to the spur than redesign the pulleys, belts, bulkheads. I can see a lot of manufacturers making that modification on the next generation of cars.

Default Need rear grip

I run carpet, with a 007. Mostly stock setup (white, and purple springs, 30wt oil, low roll center, 6 degree c hubs, double pink in front, pink in rear, 1.5mm droop front, 1mm droop rear, short rear upper links, middle setting inner pivot blocks, 1/2 traction compound in front full on rear.

The car always has agressive turn in, and when I throttle off the back loops around.

I have sway bars on order, I really don't want to loose front grip, rather just gain rear stability.

Thanks

rocket, too bad we don't have a track to try some things on. Next time we go racing, let me drive it and try some things.

I have a brushless 17.5 with very little drag brake, and a brushed 19turn, I am experiencing the same problem with each. Tekin RS speedo, JR XR3I, T-bang 19t, Tekin 17.5.

ok hold the spur and spin one rear tire. if it is crunchy it needs to be rebuilt. Now hold the spur and one rear tire don't let them spin. try and spin the other rear tire. if you can spin the other rear tire you need to tighten it. If you can spin it but it takes a lot of force then it should be good.
