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 having trouble picking a steering servo. I'm leaning toward the Savox 2273SG. My question is will I have brown outs with it? I'm going to be running the futaba 4pk for my radio and the tekin motor and esc. I think I have to switch the bec on the esc to 7.4v. If I do that will I still get a brownout? Should I also get a glitch buster for peace of mind?
Thanks

Not heard any complaints from brown outs with anything other than Spektrum's older gear. Not experienced a glitch with any of my receivers running on 2.4GHZ. The old days with brushed motors, another story entirely. I wouldn't worry about it, build the setup and deal with any troubles if you experience glitches. The 4PK is a very good radio and not likely to experience any troubles with it in your buggy.

Everyone is going to suggest what ever brand they are currently having good experience with when talking electronics. For me, I have had good luck with Airtronics and Futaba servos, just pricey and I do not think they perform as well in their given price points against brands like Savox, Protek and my current favorite, MKS. MKS is right up there with the top of the line Airtronics and Futaba servos, I just like their build quality better on the MKS, about the best I have seen but they are pricey.

Although I have not experienced it directly, I have read on many other threads that people have a lot of brown out issues with Savox. Apparently they are power hungry. I have also heard of issues with Spektrum equipment. I do have Spectrum and I have never had one glitch, so I would say that it is not universal. I have run Spektrum and ProTek servos (all with RX8 ESC) and have had no issues at all.
Others have said adding a glitch buster cap will help with the brown outs.

Same as what others have said, SMC are great. I've been running them for a couple of years and have absolutely no complaints.

I've been running the savox brushless 2274 and 2273 in my sct and ebug for 3 years and never had a problem. Just used rx8 gen2 on 7.4v bec.

I use both of these in my buggies and truggies with Futaba (4PK and 4PX) powered by both Tekin Rx8 (Gen 1 and 2) as well as a HobbyWing SCT Pro. No brown outs.

Never had any glitch issues on 6v or 7.4v

Thanks for the comments. I think that's the servo I will get.

Yeah, depending on the battery I'm charging. My charger maxes out at 10 amps (regardless of overall wattage) so my 7200's aren't getting 14 amps. But my 4400 shorties I charge at 10 amps. My 2200 shorty 4s packs I charge at 5 amps.
At a big race when I forgot to charge my battery I used my friends setup to charge my 6500 4s packs at 40 amps, so they can handle it.

You shouldn't have any brown out issues with the Futaba radio, or any other high end radio for that matter. The Spektrum radios have issues with them. You will get more performance from the servo at 7.4v.

I had brown out issues with Savox while using Spektrum. Switched to Futaba and haven't had a single issue. I use the 2274 and 2273 in both my nitro cars and my Futaba handles them flawlessly.

I bought the new .3 hinge pin holders as well as the .3 upgrade kit from fierce rc last week. I went to start installing and when i pit the front together i noticed alot of front to back slop in the arms. Seems like the hing pin holders are not getting tight enough on the arm. Looks like i may have to shim these. Has anyone else had this issue upgrading there .2 to a .3?

There should be a small amount of forward/backwards play, but not excessive. New arms or old? Are they worn, specifically the bump out that would be near the insert?
