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.

Great info! Thanks!

Finally got her built up last week and ran it Saturday in my first ebuggy race. With the box setup and only adjusting for ride height I placed 4th! Excellent platform, can't wait to get it totally dialed in.

For my buggy I'm thinking of doing 7000/5000/5000 (F/C/R) for the diffs. I'm looking for a setup that will be easy to drive so if you have any input that would be great. Thanks.

What kind of conditions are you running in? A lot of people are running higher diffs like 998

I will be running on a track that takes 20+ seconds a lap, it has medium grip, and I will be currently running in 40*F weather. I will be also running a 2050kv motor (because I got a good deal on it), and I've heard it's pretty rough so I'm thinking a lighter center diff. Also why so high on the rear?

755 should be a good start. The higher diffs pull over bumps better.

I'm at 7/5/5 on a loose track. I will report back how it goes after a race this weekend on medium grip.

Have you run the box stock set up yet ? If you have not , I think you should . Diffs are so track dependent that there is no one size fits all . You really need to try the base line , and adjust from there for what YOU want the car to do . Skipping right to what others tell you to try is a waste of your time unless you drive the same track , and the exact same way they do...

Default Diff ring gear grease

Just wondering how much grease people put on the front and rear diff ring gear? Just enough to coat? I usually end up with a bunch of grease in the diff case so I may be using more than necessary.

I just put 4 little dots equally spaced around the ring gear. You don't need much at all.

I just got the buggy and all I have to say is that it is awesome and seems pretty easy to drive. (Only drove it inside my house since its raining outside haha.) I need to paint my body then I'll post pics.

Any suggestions on what I can do to gain a little more traction? I was able to pull off another win today with this buggy. 2 out of 2. Just lacked a little traction when I needed it. Had to be really light on the throttle. I use to be able to hit the throttle hard in my old Mugen.

Is the rear swinging out? What is the track like? If you want it to hook up more you can mess with your rear hinge pin setting with a lower roll center, lighter center/rear diffs. Springs. Tires?
