Gear Diffs
Just a quick one about gear diffs....
Ive had 3 or 4 of these now and every signal one feels different when I get it out the packet. Even after a rebuild with the same oil they feel different also. Some feel really smooth whereas others feel notchy (but not where it locks up), but you can feel the gears turning, if that makes sense.
For example, when in the car, with one diff I turn the wheel and it turns the whole drive train (10.5 and pinion attached), but when turned in a diff action it feels nice and smooth, where as another will let me spin it without moving the drive train.
Is this normal?
Thanks

Brandnew
one piece spur/pulley for the Top Photon (pictured below). It is made from black acetal, a strong general engineering plastic and being one piece, is 100% concentric, machined to a very high standard. It has 12 holes drilled through the spur part to make the component as light as possible. It is available in various tooth sizes in both 64dp and 48dp
Made in EU!!

Yes mate One of the team driver suggested me to use 48dp spur gear ,many team driver using 48dp over here...
5 euro or pound is ok but I can't afford 20 everytime...
But I must say I love that product ,a little pricey that's all...
Anyways ordered alloy pulley set I can't wait for delivery

€20 would cover a spur and a set of centre pulleys I'm guessing if that's the case.

Yes mate true ...
That new item is one piece sandwich pulley and spur together very good idea should run true like that but if it goes wrong we need to bin it as it is with pulleys =€20
Not very big deal but you know

You know that gear diff gives too much extra rotation to the car ,thicker oil helps to slow it down but is there any alternative setup changes to archive that ?
Like toe-in angle etc...
I wish the size of the gear diff was similar to spec-r one
Thanx in advance...

Even though tolerances are pretty small, you will still see a difference between diffs. Shims may not be equal or maybe more lube in one. I ran 120k in the front last weekend and while rebuilding it, I took it apart about 3 times to get the right amount of lube in the diff. Too little lube and it will spin too free for the weight of oil. Too much lube and it will leak and feel funny. Trial and error.
Where is everybody getting there gear diffs from?

I got some from RacingArt Company and from topracing australia.

How much more do the alloy pulleys weigh than the stock ones? Just curious if this would effect the total rotational mass of the drive train. Granted brushless motors are making things easier, but I just wonder if they really are worth putting on the car. Or just buying an extra set of the the stock ones. For quick gear changes.

To be honest I don't know the benefit of using alloy one...
I was thinking it may fit better to kawada spurgears but rcmarket said they didn't improve that point
Maybe you should try that one piece spurgears...

The center pulley is pretty nice. Fits very well and spins very free from obstruction. The best part is that you don't have to glue the sides on. I didn't have a scale to measure the difference, but the aluminum piece is heavier than the plastic original.
