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.

Thanks. Based on the order you have, it looks like these are your setups from a lower grip to higher grip track. Is that true?

Pretty much, I like the rear to be locked in.

Just wondering what pinions you guys use? I ordered a 19t for mine with an 1800kv motor. Worried it might be a bit much. Large tracks

Here is how I do the transponder placement. I use a corner from an old lexan body, in this case from an old 2wd buggy body, and glue it on to the side of the servo mount location. Then I use normal mounting tape to stick the transponder down to it and run the wire back along with the servo wire. The down side to this is you do need an extension wire if you're running the RX in the RX box. The plus side is it really can win you races. Here's an example in video, pardon the driver errors, as I was working insane hours and then coming to race after. I'm in the yellow, and of the race is at about 5:35 in the video.

+ YouTube Video

Default Transponder

I was looking at the space on front of the servo. I didn't know if it was too close to the metal chassis. Sounds like its okay to mount there.

at this point has everyone bailed on the new trailing spindles and carries and back to the originals on the buggy and truggy?

I think this entirely depends on driving style and track type, and if you want to run the universals or not. It is definitely NOT TRUE to say that everyone has bailed on them. It IS TRUE to say that they're not the best option for everyone in all track conditions.

Yup, it works great. I'm usually one of the stronger signals to the loop. Just be careful to route your wiring well and tight, because you definitely don't want it getting caught up in the steering mechanisms.

What do you loose with the trailing spindles or I probably should ask what is the diff between the way the two different type of spindles handle? I think my undersanding is the trailing ones smooth out steering a little which also means the are not quite as responsive, but that could be totally wrong.

A trailing spindle will mellow things out the faster the track is . It will make the front less nervous at speed and go through bumps a bit better. They will hurt you some if your track is tight , slow , and has a lot of 180s.

I am a little worried myself. I just got the 48.3 parts to upgrade a .2 and it seems like some of the changes may be a step back if you happen to LIKE the 48.2. It seems the 48.3 is possibly suited more to those who DID NOT like the 48.2 and less like a evolution of the 48.2 . If that made any sense ... But I am looking forward to getting the conversion done and learning first hand what's up .

The trailing spindle is what makes the .3 so good IMO. The old buggy was twitchy, making it harder to drive.
I driven my .3 on a very small indoor track, can still turn inside any other car on the market.
