Bob B 8/10/17 - Should I start with the kit setup?
The kit setup is a great place to start. One other option that many of us start with is Joe's rough track setup. You can find that setup here
In order to run it you need 3x2.1 pistons and 3x2.0 pistons. (They are marked on the sheet as 3.1 and 3.0).

Matt W 7/7/17 - 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.

Tips and Tricks
Setup Sheets:
Setup sheets for all Tekno RC vehicles can be found here. Please be sure to try our recommended setup. It works very well on most tracks.

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 using the xt90's on mine and really like them.

I used to use EC5 but I'll be honest, the damn things were too hard to pull apart after a run. My son couldn't get them apart at all and I could barely get them out without feeling like I was going to rip the wires out when it suddenly pulled free.

So I just switched everything to Deans for this new build (after Danny at SMC said all he uses is Deans) and they work great.

I use XT150's but i'm weird. Allows me to run single 4S or double 2S/3S for 4S/6S power in series without any additional adapters and are super easy to solder and connect.

Never had an issue with EC5's, but look into Anderson Power Poles... I pretty bought a lifetime supply of them from McMaster Carr about 10 years ago for about $30. I *still* have a huge pile of them.

We have always used deans,the key is to strap you wires down so they are not flopping around. At big races I put a little piece of electrical tape on the plugs.

Tried them all and the Castle connectors. I always end up going back to dean's. The traxxas plugs come unplugged alot and the others are either too bulky and flop around or are hard to take apart.

I need another car stand. I have a TLR plastic one for my 22-4 2.0 now which works ok. Does Tekno have anything like that?

Anyone else remember when Tekno said they were working on a setup guide and were going to release it. Anyone have any info if it died out or is still in the works?

Not that I know of but Petersen Metal makes really nice stands with your name cut into them. I have one and it is REALLY nice. They are based out of Hudson, FL.

A little dielectric grease on EC5 connectors makes them work excellent. We had the same issues till I started using dielectric.
