Tekno RC EB410.2 4WD Buggy Build | CompetitionX

Originally published on CompetitionX

The original EB410 was an instant success, winning races in the hands of both beginner and seasoned drivers. The car was easy to work on and built like a tank, making it a solid performer when others failed.

The car wasn’t perfect though, and soon the tinkerers came out with optional ways to mount things (like the rear shocks). This enhanced the performance of the car, making it an even more fun car to drive.

The cool thing – Tekno was watching. They not only gathered this info, they built the .2 with most of these enhancements right in the box. This is pretty huge, basically giving the customer a perfected iteration of the first gen car.

I’m lucky enough to, once again, get one of these wheelers to build, drive and race! This time, though, I’m not going to be rocking it in the 13.5T class – we’re going right up with the big boys – MODIFIED!

So, tag along as we assemble the EB410.2 in our step-by-step guide. However, before we start the build, let’s go over the support parts we’ll be using:

Transmitter:
Once again I’m going with old faithful – my Futaba 7PX. Besides being completely comfortable with it, it brings a whole lot of technology to the palm of my hand. I love the touch screen, easy menu system, cozy feel and, of course, the ability to make a bazillion adjustments to my ride while up on the driver’s stand. It really is an amazing radio system.

Servo:
I used the R1 Wurks’ low-profile servo in the .1 version of the EB410 and fel in love with it. Super speed and aggressive torque – .06 and 230oz respectively – make it an absolute powerhouse for 1/10 wheeler. I also love the stealth look; all black wiring, CNC-machined case (anodized in black) and just the right amount of milling! Plus – the kicker – all metal gears inside. With an open wheel ride like the EB410.2, you definitely need something that is going to hold up to some heavy crashes. This servo is up to that task!

Battery:
Providing the juice to the rest of the R1 power package is one of their 120C 2S Enhanced Graphene Shorty LiPo packs. This pack fits snugly into the carrying tray and should provide more than enough power to the 7.5T brushless motor. It features a super low IR and 5200mAh of life – making 5 minutes (or even 10) should be pretty easy.

ESC:
I am lucky enough to be able to try one of R1 Wurks new Digital-3 2S ESCs. This new gem can be used in either stock or modified racing and features some of R1’s newest tech, including updated internal design, built-in BEC, X-Lock brake response and an aluminum case (with 30mm fan). It also includes access via a wireless adapter for firmware upgrades or live ESC monitoring. Plus, just about every onboard parameter is programmable! Lots of stuff to play with on this bad boy!

Motor:
I know the biggest 4WD buggy class uses 13.5T motors, but for the .2 version of this car I really wanted to push the limits. Well, not really the limits of the car, but MY limits. It’s been awhile since I ran 4WD modified buggy, so I decided a 7.5T motor was in store. This motor has been improved over the V15 versions and uses a proprietary stator laminate material to keep it together when spinning at super high RPMs – something I need as I plan on driving this thing strapped!

Wheels and Tires:
Using the correct rubber on your ride can make or break its performance. At OCRC Raceway, Pro-Line’s Electron tires are a good starting point for the hard-packed track. I mounted up a full set of front/rear Electrons in clay compound, gluing them to a set of PL’s Velocity wheels (using, of course, Pro-Line glue). While these tires have proven to provide excellent traction, how much they wear will depend on how strapped I drive. I don’t expect them to last all that long.
