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.

My SL servo has been replaced, but I also made some corrections with the .4 (brakes ) that should help my lap time.
Looks like I need a practice night to see which one I can get around the track faster

You must of had just the right type of hit. Hinge pin + shock shaft, guessing on the same a-arm side? 1st time out for me this weekend and the beginning went a little rough, rougher than normal and all's well. The amount of teknos @ the track and the amount of wrecks I witnessed per heat & main with the cars still good to go.

hold on to those parts and send them back to Tekno for that warranty deal if I am reading it correctly.

One thing I noticed at least in the SCT410.3 was a whole lot of hingepins bent. the previous owner had like a warchest of them.

Hinge pins on this car are very soft imo. I've bent several. The argument is they bend and don't allow the arm to break. I made some from drill bit blanks and haven't had a problem since.
