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.

Sorry about that. Alot of us have been tekno for so long we assume that people know that part and forget about it. I actually buy them in 10 packs off ebay so I always have them in my box. This has helped with nitro's several times in the pits to bypass bad on\off switches.

The nice thing about the 1268 is I can run it in any car/truck. 10th or 8th. I don't have to have different stuff for nitro buggy, different for 10th, etc.

I stopped running a switch like 7 years ago. The only one I'd consider is the Ko, but at its price I'm good on ec2

Wanted to share some feedback on some changes/new parts. Mark was using our new HRC hubs TKR5199B and low frequency springs TKR8767 TKR8763 available through your local hobby shop or online.

I tried searching and didn't find the exact answer.

I'm struggling with off power steering (or just getting through a corner tight vs taking it wide)

I used the Joe Bornhorst setup but I have gotten so far away from that that I'm not sure what to call it.

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.

Whats the surface your running on. Is it loose, dusty low grip, medium grip and jumps sizes. Maybe try going down in diff oils. I run 5/5/3 on a dusty low grip track and get great turn in and out of corners with 2 degrees camber with 1 degree toe on the front.

I have the same issue on low grip tracks. I've tried every combination of diff oils from crazy light to stupid heavy and it just doesn't rotate like my other car does. I have the new hubs but haven't had a chance to run them just yet.

How much did you reduce it by? My rear toe inserts are currently 2 dots facing in. Which I think is 2deg of toe.

shortening the wheelbase will also help the car rotate.

I agree, but on this car it also has negative side effects. Sliding the hubs forward increases the dog bone plunge and makes the rear too stiff under power. I have to run it back a bit to keep it from getting kicked around real bad through bumps that are hit under power.

The new hubs help reduce mid to exit roll. Basically allows you to get on the throttle sooner. We recommend these for every track type. Allows you to drive the car harder out of a corner.
