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.

We'll see where that leads.
Track is about the same im running 7.7.5 and its great also 6x1.6 450/425 green/red

If I was running on a smooth / high grip track that would probably work. I have never been able to make heavy weight oil in the center diff work on our tracks.

How long should the shock boots last? Mine look like Swiss cheese after a few packs.

The new style like is used on the .3 or the old style? The old ones ripped apart pretty quickly. The new ones are a lot better.

I moved to HB shock boots as they lasted longer than the old ones. The new ones seem good so far

Built my EB48.3 last week and tested it on the weekend. I actually bought 2 but the 2nd car hasn't been built.

I built the car stock aside from Jconcepts Finisher body, Delrin shock guides, Proline trifecta wing (not the lexan wing) and I don't run the centre or rear brace

Unfortunately it wasn't my home track which makes it a little harder to compare, but the new car handled the bumps better and landed better off big jumps (especially if I over did it and missed the landing ramp). The wing buttons seemed different to the old ones and when I got clipped in the air and landed on the wing they broke off. I replaced with Avid buttons off my previous car.

Car had plenty of on power steering (more than my last car) and I had no rear grip issues, however, I found it had a lot of turn in understeer and I couldn't carry any speed through the hairpin or sharp corners. I had a similar issue when I first got the old car, so I will make some changes and get it fixed.

I have put a dint in the chassis already. It looks like it landed on a rock right at the thinnest part under the battery. It won't have any impact on the car.

My home track is being rebuilt at the moment, but can't wait to take the car for a spin somewhere more familiar

Running the stock set up, changed rear diff to 3000, lengthened the wheelbase with one small shim behind the rear hub, everything else in front. I'm running SMC 6500 4S, Tekin RX8 Gen 2 with T8 1900 kv with Proline Blockades. Running on hard packed with dust.

Wow, this Ebuggy is so fast, I honestly cannot think it could get any better. I really love this thing. It really likes to drive aggressively and fast. My first year back into RC after my last car (Losi XXT CR Graphite plus...lol). Really love this thing.

This is almost exactly what i thought of my car with its initial run. I will try a little more toe out, thinner sway bar and back ackerman to get that initial feel the next time i am able to get to the track.
