Welcome to the EB4.4 Wiki page.
If you edit the page, please add your name and date prior to your addition. While an admin can view the history, this makes it easier for everyone to just check updates. We'll put the newest additions at the top.

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

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.

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 bought an MKS X6 HBL599 for my .4 and so far I am pleased with it. Has all the power in the world and it's quick and smooth.

I'm in the market for some servos and looked at the MKS HBL599 and I just can't get over the cost of them. It seems like $189.99 for a servo is crazy expensive.

Really love my ProTek 170s!!

I would look into ProTek or Highest (the company that makes the ProTek) I've been Running them for years and they work great and haven't had any issues.

I have no experience with hobbywing, I have only ran the Tekin RX8, and teh SMC ESC. For cost effectiveness, I would without a doubt grab the SMC.

I have the Protek 170s, and the highest dt2100 in a couple vehicls. My next servo purchase will be a proamps, Decently priced, and a 2 year warranty. They are new to the USA, but are very well respected overseas, and in in austrailia.

I use the Futaba S9372SV

http://www3.towerhobbies.com/cgi-bin...?&I=LXFSGA&P=M

Awesome specs at both 6V and 7.4V

please note however, its a fat servo, so it was a bit of a chore to squeeze it into the mount location.

Only shows specs and rated for 6v, not 7.4. For $150, I would expect the specs and design to be a bit better. And 1 year limited warranty.

Ah, I found it on futaba's site. 342 oz and .06 speed at 7.4v....Curious why Tower doesn't show the 7.4v specs....7.4v specs look better for buggy.

I'm using the Protek 150T. 1st time I fired it up it was so smooth and quiet compared to what I'm used to, Savox. Specs are very nice in either 6v or 7.4.

Nice! I still have my S6280 in my .3 Buggy so i can test some changes i have made to it. I am testing the same 150T in my .4 buggy. Its fast and smooth when testing on my living room carpet. I have not yet tested it outdoors or on the track.

Have you had any issues with how close the xr8 is mounted next to motor? Seems like a tight fit.

Lot of servo options these days. I'm still a big fan of Hitec because of the service experience. Outstanding performance and proven. I have 7950s in service nearly 4 years with only fresh grease on gears once a year. I'm a clean driver and do lots of preventative maintenance which helps.

I'll find out next sat how the servo does but I can't imagine not being satisfied.

Yes it is a bit close and I'll keep an eye on if I see rubbing. If I do I'll turn it with the caps facing out.

I thought it was a little slow compared to the Savox using the 89$ hobby wing esc. I guess my prob was it wasint getting enough voltage for the Spektrum.

"nvm i just looked at the spec's and it seems the Savox has better speed but no where near the torque the Spektrum has even at 6v"

Highest also makes the Reedy servos.
