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 have had this car since December. It has survived some pretty hard crashes and it still keeps going. I haven't broke anything. I'm happy I bought this car.

2 questions...
1. Is anyone running the 5-5-5 diff oil setup the manual specifies? And how does that combo work? I run on an outdoor track that is low-med traction.
2. I am putting the kit together and I am at stage of assembling the hinge pins with the arms. It says to use 4mm reamer or #19 bit til the pin falls thru the hole freely. I don't have a reamer so I used the drill bit but it didn't do anything. The pin falls thru freely but about 1/4" from the opposite end it sticks. Same thing if I put it in from the other end. It sticks about a 1/4" before coming out the other end. Wondering if it will free up after running like that or if I do get a 4mm reamer will it actually work or will it not do anything just like the drill bit didn't?

#2 - go to Ace Hardware and they will have a #19 drill bit which is 4.22mm

I built mine with 5/5/5 at first just to try it and break it in, worked rather decent to be honest. Yes arm's were a pain even with my reamer, make sure droop screws are all the way in the arms and ream the arms until the pins can fall through mostly free without hanging up......it takes a bit!

https://youtu.be/GT2AdfBfM6M?t=2m49s It works very well, and doesn't seem to weaken the arms much. I have not broken one after cutting them.

I did run the #19 drill bit in the arm but it didn't help at all. I did mic the bit and it was about 4.2mm in diameter. I wasn't getting any shavings on the bit when I pulled it out. But now that I am thinking about it I don't think I had the droop screws installed. I will try it again tonight with them installed. Thanks

For what it's worth, I can take a new arm and it will appear fairly free, but the pin won't drop through. I use my Reamer and make a few passes and then it drops right through. And nothing visible is coming out when I ream it. It really doesn't take much. Very very little.
