It's cst.

No, it's not odd going above 7 in any of the diffs. In fact a lot of the team guys have been trying thicker diffs oils as a whole, for example 997. We are finding that the thicker diff oils make the car easier to drive, keeps it straighter, and reduces the darty feeling the car can have sometimes.

Spur Gear
 

Does the plastic spur gear hold up ok?

Nearly 3 years of running EB48, never had an issue with a single one.

I have never had a spur gear fail in an EB48, 48.2, or my 48.3 unless I did something stupid like leaving the motor mount screws loose.

Good deal! Thanks. I have it in the cart. Will see if black friday helps me out. Almost got it when I got the NB48.3, but didn't want to have to purchase new batteries because of price. I see that the SMCs are reasonably priced. Wondered about the 60C, but that should be good.

The only problem I've had in 2 years with one of my Tekno plastic spurs was on my SCT410 and I had a bearing go bad that I didn't catch in time.

SMC are excellent batteries, no worries at all!

What do you guys run for plugs? In my SCT410 I have inboard batteries, but for the EB's you don't see many 4s inboard batteries. I assume Deans is likely the next best thing?

I may be in the minority, but I prefer XT60 as my plug of choice.

I like Traxxas. Easy to build and to use.

I have been running the EC5 plugs from SMC (they are different from the EC5s from E-Flite) but they are very difficult to plug and remove. It's gotten old, so I am switching to Traxxas plugs. That way all my vehicles will be on the same plug and can use all my batteries in all compatible vehicles.
I know Deans are very popular but I never had any luck with them. I was using the genuine Deans and they would come apart during a race. Putting a zip tie on them every run got old as well. Ditched them quickly. Maybe it was me and my soldering job making the plugs loose. I figure if it was that easy to not assemble them correctly, they weren't the plug for me.

+1 love these plugs. Started using them for the first time this year and I love them. Nothing wrong with Deans as long as its not the knockoffs. but the xt60 is my favorite now.

Xt60 here, too.

I use XT90. Better suited to 8th scale than XT60s. Very easy to solder and use. I switched from Traxxas plugs. Hated them.

About how big are the XT90s? The size of EC5s?
