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.

Default Universals

Good deal on the universal reviews. Keep them coming as you all get more info. I would want use them as a replacement for cvd. Any thoughts on universals in front and cvds in rear?

It is my understanding that universals are more of a tuning aid, than a straight replacement.

For smooth hard indoor style tracks, or smooth tracks out west, CVD's will be the preference.

For outdoor loamy, bumpy, rutted tracks, like some up here in the northeast at times, then universals will be a better option.

Sounds like VWduud would want the universals on his home track, and CVD's at flowood where he traveled to.

I charge at 1c ( 6.0 amps is all my charger has in it ) , but I don't balance charge every single cycle. I balance charge the night before race day , then during the race day I just charge unless the cells are pretty far off , then I storage charge ( which balances) that night. If I am going to just be goofing off , I balance charge .

The packs charge a bit faster and top off a bit quicker without balancing between heats , and I have not had any of packs (smc) suffer from it. They all still balance out great. I use a hitec x 80 charger fwiw.

I always balance charge. It is safer and not really any slower. The only part that is slower is the very last bit, and only if the pack isn't balanced already. The more often you balance charge, the less of a difference there will be, so the less extra time it will take to balance charge.

I also have the SMC 6500, which is always fairly balanced for me too. I normally charge it at the most friendly 1C rate which is 6.5Amps, but have also charged at 10 and 12 amps several times when I was in a hurry (such as just arriving for open practice the morning of a big race, or getting a pack ready after a bump up into a higher main). All SMC packs easily handle 2C charging (which would be 13A for the 6500 packs), and some may handle more. Read each pack as it will tell you what the safe charging limits are for itself (usually in a C rating), and they may be different for one pack that you think is the same and same brand as the another pack you have.

I agree. I always balance charge and at 10 amps. Those batteries actually prefer to charge at higher than 1c. That came straight from smc.

That is true I contacted SMC Racing yesterday and this is what they said:

"They can do 6C if you need to but in my testing I've found 2 to 3C to give the best combination between speed of charge and mAh put into the pack."

So now I charge I between that rate. And thanks for your input guys.

I run 2s and 4s SMC and balance charge them all 10amps every time with zero issues.

I've been charging my SMC 6.5's at 8A as that is the most I could get out of my power supply, but will be doing 10A once my new max amps PSU comes in.

I run 18t on a 2050kv tekin setup, probably very similar to a 19t on 1900kv. I feel it's got plenty of low end and plenty of high end... Temps are also generally under 180 depending on ambient heat.
