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.

Thank you, ordered. Wish I've tried that before mangling one of the collars on a brand new servo (entirely my fault):



Wouldn't spacers solve that though ?
I don't like that servo arm at all. get the new style tekno ones, and use the inner hole.

http://fiercercsolutions.com/TKR5253...e-TKR5253B.htm

They have a lower profile than the arm you are showing. I'm also not familiar with the savox 1267...And also not a savox fan at all. I've been told the only good savox servo's the model number starts with a 2 not a 1.

I personally run this servo in both buggies & SCT for steering.
http://fiercercsolutions.com/Highest...rvo-DT2100.htm I also run a protek 170s for steering in my truggy.

I use the 1267 currently in my SCT and it does fine, no issues with it being too tall or anything..

Savox 1267
Torque: @7.4v - 277.7 oz-in / 21 kg-cm
Speed: @7.4v - 0.09 sec/60

Should be fine for the buggy too I would think...

Default Servo

I just got my kit and I need to buy a servo. I usually run Savox but am open to suggestions. Can anyone please make recommendation?

I run the Savox 1268. Just make sure you also buy the servo lead extension. They are only a couple of bucks, but the servo lead isn't long enough.

The nice thing about the 1268 is I can run it in any car/truck. 10th or 8th. I don't have to have different stuff for nitro buggy, different for 10th, etc.

the hitecs are nice in that they have a really long servo lead, so it reaches the receiver box with length to spare. When I was running Tekno, I liked the Hitec 7955TG with a BEC set to 7.4V after Hitec said this was okay. worked Excellent.

It really depends on your price point.

Specs to look for, minimum 300oz of tq, and .10 second response, or better if you can swing it.

High Voltage servo's seem to be the norm these days, so be sure on what your BEC is capable of from your ESC,

I personally run the Highest dt2100 in both my buggies and SCT. It's right at 412oz and .07 second response.
http://fiercercsolutions.com/Highest...rvo-DT2100.htm

If your budget is a little tighter, and you can definately run your BEC at 7.4v instead of 6v, then teh highest dt750 is a good budget minded option.
http://fiercercsolutions.com/Highest...ervo-DT750.htm

If you prefer savox, the 2273 below hits teh specs whether your running 6.0v or 7.4v

I'll throw in the ProTek servos. Detachable leads on some models with good power and speed. I also like the Spektrum servos. I have several older models that have never let me down. The new S6290 looks really nice.
I also have a HiTec 7950 in my Wraith, good company and quality servo. Not a good one for a buggy, but I would buy another HiTec based of my experience with it.

I actually left that out. I'm running the protek 170s in my truggy with good results.

2274 is what Ty and Cav run. I would run them as well if I didn't already have my 1268. FWIW, they are almost the same exact specs.

Also I disagree that you want .10 speed of faster. I think that for the majority of the world, that only hurts you. Kinwald was famous for running high torque helicopter servos in his 2wd buggies for years. For me, anything faster than .13 is probably too fast and will likely cause me to drive more erratically. I suggest looking in that range, not to mention it will likely cost less to get something in that range.

ultimately it's preference, but I believe if you run something in the 300-400 oz torque with .13-.15 speed, you'll and up driving more consistent on the track.
