Do those spool cups require driveshaft blades?

Yes

I tried alloy spool cups when I ran the photon but the driveshaft blades didn't last very long, and when they failed the driveshafts damaged the cups pretty badly. I think if you run 17.5 you'll be sweet, with the faster classes you'll need to replace the blades every meet at least

Are those spool cup aluminum or steel?

I had the same problem when I had the TC5. The blade in the front would break when I hit something hard. When the blade breaks, the aluminum spool get chew up. It gets old after a while. The plastic spool cups hold up better when I grease them.

it says they're spring steel

Hallo,

some time ago I also have tried steel ones. There were 2 problems:

1. The blades were worn out within 2 batteries
2. The steel cups were so rigid, that all the vibrations from the front drive shafts were transfered to the drivetrain and worn out my belts faster

So the 9804388 Tamiya resin cups are the best solution for me.

Which Silicone oil or the black grease should I use in my Spec-R gear diff? the car is a 416X and runs outdoor and indoor

I tried the steel out drives today with good results. However my blades were sticking in the slots so I had to sand them a bit to make sure they didn't bind. I tapped many boards today and didn't break a blade. Obviously they will have less give and may be harsher on the drive train. All in all I'm happy with my purchase so far...

I am using 1000Wt oil right now, but honestly is still seems too light to me on carpet. Maybe outside it might work better as it seems everyone is running 1000 in it.

Agreed, I just added them to my car this weekend, & they ran all day(about 3 practice runs, plus 3 qualifiers & a main) & I couldn't tell there was ANY wear on them or the blades, stayed smooth & strong, just like I'd hoped they would. Now, I'm ready to try the Spec-R diff(should get that in the car to run next weekend, got lucky last night finding one at Speedtech)....

1000wt works good outside, I ran it last night on a partly damp track and my car was great

What brand is the 1000wt you are running?

Kyosho, I believe that's what the team used at the worlds

When I built the diff, I used 2 of the shims on each side to prevent the shims collapsing into the orings. Even though they are only 0.1mm it meant I needed to use 2 gaskets to get a nice mesh. After one meet it feels even better now, but I might give it a go with a single gasket now that the teeth are bedded in just in case the mesh is a little too loose now

Really happy though, I didn't expect it to be that good in lower grip, cant wait to try it on a dry track and check the lap times!
