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'm actually going to sell my NB, and pick up the new EB. I have a big race coming up, with 0 test and tune time. So I'm going to bring both, and try them both out. If I don't like the out of box setup on the .4, then I'll run what I know, which is the .3

People always seem to think they have to jump and grab the latest and greatest. The .3 is a good buggy, and I'm consistent with it as far as lap times. There is no reason why you can't run the .3 and be competitive. Heck, didn't stadium truck at a big event just get won with a 20 year old rc10t?

I was debating some deals on EB48.3s . One I can get,used of course, is about $200-ish shipped with some upgrades. Has me thinking about it a lot, especially as it has the uninversals.

I am happy and sad at the same time. I just purchased my EB48.3 kit last season. I wasn't planning on upgrading until 2018 season. Looks like it may be sooner rather than later :]

What doesn't work for ebuggy on a rough track? I don't think there is a track that gets rougher than the one I regularly club race on. It's an old school dirt track with loam, sand, and some hard park. It changes lap to lap, let alone heat to heat. What is it doing that you don't like? Do you have a setup sheet?
I have two main problems. First, the car gets kicked around over square edge bumps worse than any other car I have owned. Second, I seem to be able to get steering, OR rear grip. Not both. If the rear is locked down enough to be driveable, it won't steer. If it has enough steering, it has crazy over steer. The only thing it does well is jump and land. I have tried every setup out there, plus done my own setup work. The latest attempt was the newest setup on the Tekno site for outdoor, rough tracks. Including the new rear hubs, LF springs, recommended shock pistons and emulsion setup. That was probably the worst the car has ever been. It would go into crazy "tank slappers" down the straights if I hit a bump just wrong. My other cars hardly even get upset by the bumps. The closest thing I have found was the Wicked Weekend setup, but steering suffers. Especially on power. It just kills my corner speed and I end up 2-2.5 seconds a lap slower than I am with my other two cars.

Out of curiosity, what servo are you running? My buggy was pretty good last season. I just needed to tweak rear bounce (went from 40wt to 35wt in rear) and changed the front diff from 5000 to 7000 and the rear from 5000 to 3000 (more pull around corners) I have yet to test my new setup as of yet.

High torque Savox. Can't remember the number off the top of my head, but it has plenty of torque. I use the same one in my truggy and it works great.

I was looking really hard at the RC8B3e at tower ($450). Happy with the EB. I'm getting started, so if they are blowing out last years model, I am ok with it.
Sorry I can't subtract, $382 shipped.

Can anyone recommend make a servo recommendation. I use Hitec on my planes but they seems to be a little slow.

Futaba BLS371SV (263oz/.10s, 219oz/0.13s) $170
Reedy RS1806A 255oz/.06, 211oz/.08s) $170
Reedy RT2207A (294oz/.07, 240oz/.09) $170

Same price range

If you mean the hitecs you see available are slow the HS7940TH on 7.4V is pretty quiick.

I am looking to use this as I have it sitting here:

Futaba S9372SV

SPECIFICATIONS

Torque: 280 oz/in (20.1kg)
Speed: 0.07 sec/60 @ 6V
Torque @ 7.4V: 24.6 kg (342 oz/in)
Speed @ 7.4V: 0.06 sec/60
Dimensions: 1.6 x .83 x 1.46" (40.5 x 21 x 37.2mm)
Weight: 2.47 oz (70 g)

$129.99 at tower and you can get discounts and tower e cash right now. As a super saver member, works out to $16 off (spend $10 and get $23 off) and $12 in E-cash.

Speaking as a racer, not a Tekno representative, you shouldn't be in a rush to unload your proven car. You have to determine what it's worth, both to the buyer and,more importantly, to you.

I know that as a team driver, I'll get the new car. But when I look at the market and see the old car is selling for 150 bucks (just making up a number), I'll keep my old car.

To me 150.00 doesn't make up for the piece of mind knowing that if anything ever happened at a race that I could grab my old car, toss it down, and run it. It's kind of like an insurance policy that I already paid for.

Speaking as a Tekno Representative, you should definitely grab all of the updated parts. They make a huge difference in the car's performance. IF we release a new platform, you can be sure that it will be a significant improvement over the old one.

Servos: Make sure you are at least at 300oz torque. I prefer closer to 400 if possible. I am not nearly as focused on speed. In fact, my preference is around .11-.14 for speed. Which if you look at alot of the top pros, they run that too. For example, Tessman and Cav run the 2274 from Savox....don't have the specs in front of me, but I think it's like .10 at 370ish torque.

ProTek makes really nice servos as well, so definitely check them out.
