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.

Started my build tonight, quality of the parts look and feel so great compared to my previous 1/8 buggy experiences (Losi, Team Asso)!

Had some tough time building the turnbuckles though.

Always thought 8ight 3.0 chassis was narrow, now let's compare

Don't pay retail for them. You can get them on ebay or dollar hobbyz for $20 a pair.

Thanks mate! I just ordered them from Dollarhobbyz. They are less than $19 a pair, the hexes less than $9 for 4. Comparing to about the same price for the Tekno replacement dogbone, a steal! I ended up getting two pairs of the universals...Too bad Dollarhobbyz don't carry Teknos....

That's what I did, ordered 2 sets since they are so cheap. I should have gotten the hexes too but didn't think about it.

Finishing my build today. Went super smooth, looks like an awesome kit.

Quick question: done everything exactly like the manual says and have sobe rear positive camber. Strange. Anybody had this issue?

Rear camber is just adjustable by the camber links. They probably just updated mounting positions as compared to the length of the camber link at some point when doing the manual. Simply adjust the links until you get to desired camber. I would suggest starting around 2 degrees and adjust from there (I'm currently running 3 degrees on almost all tracks).

Sure, I'll adjust, just wanted to start with the stock setup and tune from that point.

Cant't wait to get in to track, the build was my best exprience so far after RC8.2e and 8ight 3.0e. Everything seems so well planned. I am mounting xerun combo HW150a + 4068 2250kv sensored motor with 16T pinion, did a great job in my previous buggies.

Im not sure if this has been asked, is there a underdrive gearing? If so, how would go about it. Part numbers if possible. Thanks

There isn't a dedicated under drive gear set, but you can do it using the ring and pinion gears from the ET48 truggy in the back of the buggy. It will cause a larger front / rear gear split than the under drive sets on some other brand cars. I have used it on very, very low grip surfaces with some success. If the grip comes up at all, it gets undrivable pretty quick. That was on my eb48.2. I have not tried it on the .3

Having had two full practice days on my EB 48.3, I can safely say this is the most fun I have had with an off-road rc vehicle. Two eight hour days burning packs and tweaking the stock setup and I have hit lvc on every single pack and it isn't from lack of run time, I am just having so much fun I lose track of time.

The stock setup was fairly poor for my medium sized, high bite indoor clay track, it seemed more suited for a large outdoor medium bite track that was fairly bumpy. I finally got some springs, sway bars and about five different set of tires to see if I could get this buggy rotating better on and off power and more settled for our track conditions. Although a couple of the faster 1/8th guys didn't show up, I was able to put down some much faster and far more consistent lap times with this current setup.

Still plenty more things to try out and work on to get the buggy even more dialed in, too many things to try and not enough time in the day to try them all. I did change out the-

spring package, F-Green, R-Yellow.

Sway bar F-24mm, R-23mm.

Droop F-115mm, R-127.

Camber -2 all corners.

Ride height F-25, R-27.

1 added washer to bumpsteer.

Front Shocker tower all the way in on top all the way out on bottom.

Rear Shock tower Second hole from all they in on top and inside hole on bottom.

Diff Fluids, F7K-M10K-R4K

Due to a fairly smooth, high traction track, I lengthened all camber links and they are all angled.

I really love how this chassis takes tuning changes and the effects are immediately noticed. Some settings required a couple attempts to get what I wanted from them, the camber links to some time moving them out in steps. In the end I got a good balance of on and off power steering while keeping the ass end of the buggy tracking straight whether grabbing a fist-full of throttle or slamming on the brakes diving into a corner. It was pretty nice hearing quite a few comments on how dialed my buggy looked. Even though I still consider myself a novice driver, this buggy is making me feel real comfortable and that is allowing me to drive it harder and faster with every battery pack run.

Just finished my build.
It was great, but I made a mistake, the winter is coming and I'll get this beauty to track in 5-6 months...
