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.

No, it's not odd going above 7 in any of the diffs. In fact a lot of the team guys have been trying thicker diffs oils as a whole, for example 997. We are finding that the thicker diff oils make the car easier to drive, keeps it straighter, and reduces the darty feeling the car can have sometimes.

I have never had a spur gear fail in an EB48, 48.2, or my 48.3 unless I did something stupid like leaving the motor mount screws loose.

Good deal! Thanks. I have it in the cart. Will see if black friday helps me out. Almost got it when I got the NB48.3, but didn't want to have to purchase new batteries because of price. I see that the SMCs are reasonably priced. Wondered about the 60C, but that should be good.

The only problem I've had in 2 years with one of my Tekno plastic spurs was on my SCT410 and I had a bearing go bad that I didn't catch in time.

SMC are excellent batteries, no worries at all!

What do you guys run for plugs? In my SCT410 I have inboard batteries, but for the EB's you don't see many 4s inboard batteries. I assume Deans is likely the next best thing?

I may be in the minority, but I prefer XT60 as my plug of choice.

I like Traxxas. Easy to build and to use.

I have been running the EC5 plugs from SMC (they are different from the EC5s from E-Flite) but they are very difficult to plug and remove. It's gotten old, so I am switching to Traxxas plugs. That way all my vehicles will be on the same plug and can use all my batteries in all compatible vehicles.
I know Deans are very popular but I never had any luck with them. I was using the genuine Deans and they would come apart during a race. Putting a zip tie on them every run got old as well. Ditched them quickly. Maybe it was me and my soldering job making the plugs loose. I figure if it was that easy to not assemble them correctly, they weren't the plug for me.

+1 love these plugs. Started using them for the first time this year and I love them. Nothing wrong with Deans as long as its not the knockoffs. but the xt60 is my favorite now.

I use XT90. Better suited to 8th scale than XT60s. Very easy to solder and use. I switched from Traxxas plugs. Hated them.

About how big are the XT90s? The size of EC5s?
