What option parts should I consider buying with a new kit?
None are required but we recommend the following:

Aluminum Servo Horn:

-TKR5251B (23T)
-TKR5252B (24T)
-TKR5253B (25T)

TiNi Shock Shafts

-TKR6017T (front)
-TKR6061T (Rear)

This car is very durable. Here are the spare parts that we recommend you keep on hand:
Tips and Tricks
Vehicle Setup Adjustments and Build Tips

Tekno RC Instructional YouTube Video Playlist


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 our 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.

Setup Sheets:
Setup sheets for all of our vehicles can be found here.

What is overdrive and when should I use it?

The NB48.4 comes stock with a 12t pinion (TKR8152) and the 39t ring (TKR8151) in both the front and rear and the EB48.4 has a 12t pinion (TKR8152B) and the 40t ring (TKR8151B) in both the front and rear.

The two sets of gears are used to overdrive the front of the EBs or underdrive the rear of the NBs. If you have both vehicles and want to try underdrive it's as easy as swapping the front diff and pinion of the EB and the rear diff and pinion of the NB. Underdrive helps on very loose tracks, when you need more on power steering or if the rear of the car feels loose.

TeknoRC has done an awesome job on posting build & setup tips on their site. teknorc.com scroll to bottom under support and see Vehicle Setup Adjustments and Build Tips link. I provided link below as well.

Vehicle Setup Adjustments and Build Tips ? Tekno RC, LLC.

Some videos also found on youtube, search TeknoRC.

If this is your first Tekno build follow the manual which provides best instructions in the industry with helpful tips.

They also have posted setup sheets under each vehicle. View them and choose your setup according to your track condition. NB48.4 JB Smooth track base and JB Rough track base are both good starting points for the conditions. Test how they feel and make changes for your driving style. Changes are easily noticed and you will feel them. Good luck everyone with your builds!

When you're rebuilding your diff, what kind of grease are you using around the o-ring and out drive if you run out of the kit stuff? Thanks

Cool. I plan on a m12S system and apparently if you contact them pre sale they can put SSR mode on them.

Stock screws are of very high quality (not sure if 12.9, but wouldn't be surprised if they are). Alternatively, I've found bolt depot has the best pricing on various bulk screws, and you don't have to order them in quantities of 100 or 1000 like other places.

https://www.boltdepot.com/Metric_soc...ts.aspx?nv=rel

Based on this, I can't say I've ever seen a "screw kit" for it (other than junk titanium) as it really just isn't typically needed at all.
