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.

Personally I never had the problem, but enough people had some issues in the previously model so it was included in the .3. Just do it barely tight enough you start to feel some resistance, and REMEMBER to loosen when you go to unscrew (surprised at how many forget that ).

Yes, quick clean of the screw and a small amount of loctite is all that's needed. Honestly I typically only do it first install and am good from there on out unless I'm replacing screws.

Battery wise, 200g is nothing. These things are ballistic missiles I tried the 4500 for a while, but honestly it's a pain to get it where you want to sit. If they made perhaps a short (height, not length), then I would try it again. So I would honestly just grab the 6500 of whatever manufacture you prefer.

I am running a smc 5200 and 6500 and just purchased another 6500. I believe you want at least 5000 for 10min mains on large tracks.

Loctite and tighten down all the metal to metal grub screws. In fact, the ones on the front and rear diff, I would clean with brake cleaner, etc. to get all the oil off. The ones on the plastic hubs are used to hold the screws in (4 per hub, 16 total). They should just be tighten until you fell a little resistance like the manual says because they tighten up against the screw threads.

I think the southern Nats steers predictably. But does have more mechanical throw than the kit setup. He removed some setup steering then shortened the link and added more mechanical along with some bump out.
I felt on high/medium bite the kit felt twitchy. But never ran it with a shock and spring change. Might have toned it down on more traction.
My 2 cents, lol

forgot that I am not using the kit springs.. using pink and red springs. Going to change the diffs and go a tad heavier with the shock oil and see what that does this week.

Like a majority of the set-ups for this buggy, I ran without the center and rear chassis braces for a few months. I struggled to get the buggy to rotate through turns as smooth and quick as I prefer. My .2 buggy was much faster through a turn and I was chasing that same feeling. I tried heavier springs, higher oils, thicker sway bars, little to no anti-squat, camber link changes, shock location changes, etc. and I still felt like the buggy's rear was stuck to the ground. Then I squared off a metal poll at full wood and bent the front center drive-shaft in ways you can't imagine .

I decided to put the center and rear chassis brace back in the car after replacing the drive-shaft. I figured if nothing else, I don't want that kind of chassis flex that allowed the drive shaft to bend like than and perhaps it would help the rear end of the car to rotate through the turns better. It was like a whole different car, it turned much smoother, was incredibly consistent and predictable and rotated through the turns like a dream. I did that after racing indoors which was on a higher grip surface. I was worried that when I went outdoors on a looser surface that the car might lack traction, but decided to leave my indoor set-up on the car for outdoors.

I'm hear to tell you my .3 is just dialed at this point. I know my set-up is running counter to a majority of them, but I feel like this car is soo much better with all the braces in!

Does a shorter rear camber Link help the rear rotate a little better?I think I remember a longer link meant more rear traction in turns.

Your ESC will take the battery and output 6.0 or 7.4v if it outputs HV from its BEC. That will be what is going through your rx and to the servos and such, rather than battery voltage.

A shorter link will tend to change between states more quickly with less traction overall. For example, it will have more traction until it breaks free more suddenly and then will lock down again more quickly. Longer will have more traction overall and break free more gradually and more predictably.

This is for me when I brake and turn, then want to throttle out straighter.

So I've rebuilt my one race day shocks 3 times and no matter what I do, the front end seems very 'springy'. I'm doing vented bladder. I've tried with no redound, 10% rebound and even 50%. It just seems very springy. No matter if I have the stock black springs or the pink. Any ideas? Rears are built with 0 rebound and feels very plush.

425 front with pinks 27mm height
475 reads with reds 29mm height.

Just a tuning option. I have never run the rear or center braces in my .2 or .3 and have never bent the chassis, or had any wear issues. The front brace has to stay in though no matter what.

I assume you are feeling these with the car ready to drive? Are you using the stock pistons?
Does it feel springy on the track, or just on the bench?

Yes stock Pistons. On bench. Haven't had time to go to the track yet. Yes, mounted ready to drive.
