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.

Finally got to run her yesterday. Rear end was a little unstable at first. Made a couple of changes but removing the center and rear braces had the most effect. By the end of the night was getting really comfortable with the buggy and my lap times started to drop. Still not perfect but still got lots of things to try. On one outing I did hit someone as I was going full bore down the straight. They decided to jump across the track and into my way...bam!!!! Flipped her back up and continued driving. When I finally pulled in the only damage I could see was a small gouge on the front bumper. Nothing broken. Nothing bent.

I have my EB48.3 almost complete.

Here is what the fit of the XR8 Plus and the new Hobbywing 4274 G2 2250kv motor looks like (this is the longer "truggy" motor).

The durability of the the tekno is unmatched in my opinion.

has anyone tried the 3 x 2.1mm piston setup and can comment on your thoughts on it in comparison to the stock pistons?

Also, in general, what is the logic by going away from more piston holes with small holes to less holes with bigger holes?

3x2.1 are for really bumpy and rough tracks. You have to go much thicker on oils. I suggest 700cst front and 750cst rear. I only tried them one time and didn't like them, but that's because I was at 600 / 650.

The bigger holes / less # should have more dampening but less pack. I wouldn't run anything other than kit pistons unless you're on a seriously rough track.

Well, not that it makes any difference, but this is the exact same thing Ryan Lutz said to me when I asked him about the 3 x 2.1 pistons at PNB.

OK quick question, hopefully it won't get into a big debate.

My current battery (6700mah) is 606 grams, my truck total weight is 7.9 pounds. I recent seen a 5000mah that weighs 468 grams. Difference of 138 grams. So trading out batteries would bring me down to about 7.4 pounds wet.

Is that 5 ounces going to make a noticeable difference? Or will it be minute to where it's not worth trading out batteries and spending the 120 for (2) of 5000mah?

Thanks.

Probably from me....because I told you right after I tried them. Just because you agreed doesn't mean you said it

It's a good question. I asked the rest of the team a very similar one because I have the SMC 6500 and 5000. The 5000 is considerably lighter, and I preferred it in my previous platforms. My assumption when I switched to Tekno was that I would need a heavier battery to make up for the lighter car. I was right.

If you run the 6500 (or something similar to it's weight), your car will be closer to 50-50 balance left to right. One of the guys posted a pic of his car on the scales with the 6500 and Tekin electronics and he was dead on.

So my suggestion is keep your heavier battery as it better for our car

I have 2 6500 smc packs and 2 5000 packs and I've never weighed any of them, but haven't ran a 5000 mah pack in 3 weeks the car just feels better with the 6500 mah packs. So the above likely is noticeable or was to me...

Need a setup advice... I run almost stock setup and have a problem with sudden traction lost when driving through a tight corner. It turns well, I keep turning, waiting till turn ends and suddenly the car looses rear and spins. What shall I change in the setup to get rid of that strange behavior?

Questions?? eb48.3 ride height set up

To achieve 27 or 28mm ride height in the front I have to turn the shock nut all the way down!!! and barely make to 28mm. (Back is 29mm) (Joe Bornhorst Southern nats. set up)..... I had a team driver look at it and we could figure it out. Check every connection to assure correct but could not find anything wrong.. He thought I might have gotten a wrong spring size in the kit so he gave me some longer springs but when I got home I checked and the 65mm black front springs are correct!
He runs a 27mm front ride height and his shock not was about on the middle of the threads... like I said I have to run nut all the way to bottom of threads to get 27mm! Does any one have a suggestion or clue why this is??
Thank you!

Thanks guys. You guys saved me 120 bucks. Lol.

Maybe I should've weighed my motor, esc, servo and rx. That would've given me a better idea of a balanced truck. But I'm sure they weigh more than 468 grams.
