I come from on road carpet, lots of 12th scale and sedan, so I`m used to twitchy. I also run with a very tiny wheel on the radio.

I agree.
SCT's are a bit different on steering, they can be VERY aggressive and many change exponential or use slower servos. I haven't had any issues at all with a fast servo (.08-.10) in the EB48 and would highly recommend going that route if you can afford a quality fast one.
200oz should be sufficient for most SCT and 1/8th buggy, personally it wouldn't be sufficient for truggy though. I think the 300oz (like the 7955TG) is a bit better suited.
Might want to check those numbers again there bud <.12 and definitely .08 is considered fast for heavier vehicles, especially when they have the torque to actually supply the full wheel turn at speed at full stop. Onroad is definitely a different story, as fast as possible is never a bad thing, but we're not racing on carpet in this thread (unless you're overseas with one of those interesting tracks that also has carpet and astroturf hehe).

I've been running a DS-1015 in mine since last August and haven't had any issues with it. They are rated at 200in/oz at .10sec.

Me and you are exact opposites. I cannot drive a twitchy car for crap. I've got a .15 servo in my eb48 and i still have expo turned way down. That was my main issue with this car, box stock setup was waaaay too twitchy for me. I've been making changes and i think i've got it a lot more stable and easy to drive now. This is my first e-buggy and i've only had it a couple months so i'm not really used to how the class drives in general. It's amazing how much easier it is to drive the shortcourse. After going right from an e-buggy heat, to a shortcourse heat, the sct feels like a piece of cake to drive.

Ill stick with hitec 7950th.

What kind of gearing should I use for a tekin t8 1900kv with my eb48 for a very large outdoor track

I'd say 18-20t pinion.

FYI, go to the first page of this thread. There are gearing recommendations along with other good info. Just scroll down to below the bearing chart.

I use an 18 on my 1900 on an outdoor track with 27 second lap times.

What s everyone think of using the +2mm hex's all the way around? I see some setup sheets say +2mm just in the rear.
I've always felt that wider offset will remove traction at that end of the car.

If you're running on a high traction track and need the width to keep the car from rolling then do it. If you just want to settle the car down only put them on the front.

I had a 18 on mine on a large outdoor track (37 sec laps) and mine went into thermal shutdown at 8 minutes. but I am in NC and it was in the 80's that day

First run with my brand new EB48 today! First run with any 1:8 electric buggy as well. I used to be a Short Course driver. But not anymore... :-)

The car literally flew around the track. It was so easy to drive. It was so responsive. It was so exact. It was so forgiving. It was such a joy all the way!

The only bad thing, and it was really bad, was that I broke two clutch bells within 58 laps: One TKR4126 (16T) who lost two teeth and one TKR4127 (17T) who lost one tooth. I was very suprised by the bad quality of these parts. And so was my fellow drivers at the track. They are said to be made out of hardened steel but it seems more like they are made out of some other and more brittle material. They are not at all as solid as the metal spur gear (TKR5115) which is also said to be made out of hardened steel.

Is there anyone else who also has had bad experiences with the Tekno RC clutch bells? Is there anyone using a corresponding clutch bell from another brand with success?

+1 for the Hitec 7955 TG as the best servo for E-buggy. The DS 1015 is too weak for my taste.

If you run a T8 1900kv on a big track with a good straight, then a 19 tooth pinion is perfect. Timing less than 10 degrees on the ESC. If you are too slow down the straights, then it's time to get a 2050.

I drive the silver/yellow EB48 with yellow wing and wheels.

Just finished machining up a set of 8 hole 1.3mm pistons for next weekend. Just waiting on my new speedo to come in and then its time to open a can of whoop ass.
