Welcome to the EB48.3 Wiki


What option parts should I consider buying with a new kit?
None are required but we recommend the following:

Springs:
Low Grip Track:
TKR8772 Yellow Low Frequency Rear Springs and TKR8762 Grey Low Frequency Front Springs

Low to Medium Grip Track:
TKR8773 Orange Low Frequency Rear Springs and TKR8763 Black Low Frequency Front Springs

Medium to High Grip Track:
TKR8774 - Red Low Frequency Rear Springs and TKR8764 - Pink Low Frequency Front Springs

TKR5199B HRC Rear Hubs (L/R, CV or uni, EB/NB/ET/NT48/48.3) - Improves stability of the rear on mid to corner exit. Able to be on power earlier on corner exit.

TKR6146 - CNC Delrin Shock Cartridge Set

TiNi Shock Shafts
-TKR6017T (front)
-TKR6061T (rear)

This car is very durable. Here are the spare parts that I recommend you keep on hand:
TKR5020 Hinge Pins (inner, front/rear)
TKR6061T Rear Shock Shafts w/ TiNi Coating and TKR6017T Front Shock Shafts w/ TiNi Coating
TKR5286 Front Suspension Arms and TKR5184 Rear Suspension Arms
TKR5194 Spindle Carriers
TKR6009 Shock O-Ring and Bladder Set (for 2 shocks)

Tips and Tricks

List of Vehicle Setup Adjustments and Build Tips can be found here. There are several videos and articles detailing the building of shocks, diffs, camber links, etc.

Page 3 Step K-3
Put the screw in upside down so that the head of the screw is in the hex spot that's molded into the spindle. This will aid in clearance in full droop / full steering.

Page 12 Step I-2
Use no less than 4 shims on the steering spindle to limit steering throw. I actually just use one 2mm ball stud washer from my 10th scale stuff since each shim is .5mm.

Setup Sheets:
Setup sheets for all Tekno RC vehicles can be found here.

Warranty Policy:
Tekno RC is the only company in the industry that will give 50% off of parts if returned to them using the General Warranty return policy found on their website. The parts can be lightly used or completely abused, as long as the part is still being produced it's covered!

Piston Drills:
Some of our setups recommend using pistons that are enlarged. For instance 4x1.9 or 3x2.0. To drill the pistons we recommend the following:
GMK Supply Piston Drill Set
16PC Metric Bit Set Metric Sizes 2.00 to 3.00 MM.

I am using 7/7/5 in the diffs and I believe 425/ 475 in the shocks. The car just won't turn into the corner, I can't comment if its getting out of the corner well because I have to go so slow to setup for the exit.

Any help would be appreciated.
Please post a setup sheet so I can offer help specific to your setup. Would recommend looking at your diffs and make sure they're free. Off the top of my head, raising the rear ride height or dropping the front. Lighter front sway bar should help a lot. Removing one or two steering stop washers.

It's probably a medium grip medium sized track. Jumps aren't really that big and it has some tight technical turns which is my biggest issue.

Honestly, I have changed it so much that I don't even know where it is. It was the Ryan Lutz labor day shootout from 9-6-15.

I'm going to blow the whole car apart this week and change everything back to that original setup and start again.

Yeah I can't get it to attach. Keeps saying file size is too big. Anyone know how to reduce the file size of a .pdf?

EDIT: Maybe this will work...

One of the easiest things you can try is removing the steering stop washers. A lot of setups call for 3-4 washers but for my particular driving style I just can't use them. I run the screw only. This buggy has a ton of steering built into it so a lack of steering on a tight track should not be an issue. Keep us posted on what you try and we'll try to get you sorted.

I removed my rear sway bar, pink springs up front 10/7/3 diffs rear ackerman arm position and removed 2 of the bump steer washers on the ackerman arm. locked down my servo saver, And I had to reduce my epa on my steering because it was so twitchy until I got used to how well it turned. light years better hope this helps

I also ran less droop I just ey ball'd it about 3/4 of a turn on the screw and that helped when coming into tight turns after being hard on the power

From your setup sheet I'd try 24mm or less front ride height and 1 toe out front.
The camber links are already giving you quite a low front RC compared to the rear RC to a car that, as said, has tons of steer.

My two cents as some says

Edit: Something just went across my mind : what tires are you using ? Sometimes it's as simple a that.

Matt, the biggest thing that I have found is guys are using other brand oils in their shocks and diffs and they don't feel the same. I was one of them. I switched to PT since the rest of the team used it and voila! My car does everything right all of a sudden.

If you don't want to switch fluids, I suggest going thinner than whatever is on the setup. If it says 7-7-5, try 5-5-3. In general PT seems to have a feel of being 2k thinner on diff fluid and 1/2 wt (50 or so cst) on oil.

See my reply to Matt about the oils. Also you pretty much always run the front lower than the rear. I usually am 2mm lower in the front, but some guys go 3-5mm lower. Start at 2mm and see how you like it.

My tire choice depends on how much dust the track has on a given day. If it's dusty I'll run something like a Grid Iron II or Holeshot. If it takes rubber and gets a groove I'll go to a Blockade or switchblade. Those are common choices among everyone racing here.
