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 running the outdoor recommended setup for my eb48.3. How do you guys compensate for temperature change in your diff and shock oils? the setup sheet says 80 degrees F. It is around 95 F at my track in the summer. How much should i go up in my oils? Thanks!!

Is it worth going to a 2100kv motor from the 1900kv motor. just moved and new home track is larger.

I ran both 1900kv with 18T and 2200Kv with 16T in EB48.3.
With 1900kv I had more control with throttle in the air and enough power to scream through straightaway in Revelation Raceway (huge)

With 2200kv I had more torque(truggy motor) and top end but the power band in the middle smaller causing it harder to control in the air. Nevertheless, it ran cooler than my 1900kv so I switched to 2200kv in my both buggies

I've ran both on my .3. 1900kv with an 18t, and 2100kv on a 17t. If the track is fast and flows well, the 2100 will shine. If it is tight and technical, the 1900kv will shine.

That being said, I didn't really have a preference, but ended up running the 1900kv everyplace on 18t, and if a really large fast track, I'd slap a 19t on it. (pinion change quicker than motor swap) Basically because I liked the 2100kv better in my truggy. (Both SMC motors)

My local track is large with big jumps and long straights. You're hitting triples barely under full throttle with a 1900kv and 19pinion. Temps are 150 after a 10 minute main. I thought about getting a 2100kv but if you have somewhat of a heavy finger I'd say just gear up. That's what I did and have enjoyed it .. easy and simple change.

Have you raced on the new track? Do you feel like you're getting pulled on any of the longer straights?

Of the pro setups that I seen who run Tekin, most run the 1900kv motor. They will simply add some additional timing if they need more top end.

I run the Tekin 1900kv in my .4 and in the .3 exclusively. Always ran a 19 tooth pinion in the .3 (17 in .4). The 3 tracks in my area vary greatly in size. Never crosses my mind that I need more of less motor on any of them.

I just got a .3 roller too. 4076 2000kv motor for $30 and a JX servo for $28 on Ebay. I put in my Mamba Monster 2 (so big it barely fits) and took it to the track. It runs really good and the motor tested under 100 degrees F after the race with an 18t pinion. Really happy with it so far.

Depends on your driving style. Go out and run it, then come back with what it's doing that you don't like.

Stock diff oils in the .3 are 5000 across the board.

For the shocks;
400 in front
450 in back
