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 believe it comes on smoother than a 1900 4s. But after about 60% throttle it's like turbo kicks in and makes it even faster.

The eb48 will do just fine there seeing as how fast it turns.
Would you have any setup recommendations for that track. I have a eb48.3 on the way, but not sure what setup to start with.

Each motor/setup is different. Very similar top speed and delivery though.. on 6s you should be around 1350-1400kv max. Anything higher makes gearing impossible or just causes too much amp draw reducing the gains from actually running a 6s setup. Unless you are just doing speed passes that is.

Is that the arm mod in the second picture in the link? Also what does it do to the buggy's performance?
Yes, that is a version of the arm mod. The point is to prevent dirt and such from building up over time inside the arm/hinge pin area, which keeps the suspension more free and consistent over time with less required maintenance to keep it that way. As long as your suspension is free from reaming vs free from the arm mod, your performance will be the same. It is just easier to do with the cut arm mod.

Do you guys think tekno will eventually make a precut arm?

All the dang time. I have tried various "fixes" but nothing seems to work.

that's what I mean : the kick that actually bothers me a bit about 6s. perfect for pure bashing, but disturbing to put torque on a loose ground. did you change the esc setup ? what about the 20t pinion ?

Yes, and im guessing chassis flex. I don't have the center brace in and my BIL doesn't either. I don't know if that would help any. We both always snap one of them when we try the 50ft double on my track.. We quit trying that jump and haven't had any issues since.

I went back into my esc and changed the limiter back to 80 and adjusted my throttle curve on my mt4s. Now she accels smooth as butter. I forgot I ha it set up for my eb48sl that was on 3s.
