Tekno RC is proud to announce the newest revision to our stable of innovative RC vehicles – The SCT410.3 1/10th 4×4 Competition Short Course Truck. The SCT410.3 is an updated version of the original SCT410 with a slew of new parts and improvements. The SCT410.3 leapfrogs over the 4×4 SC competition in terms of performance, durability, and value. We have our customers’ best interests at heart so there is a clear path to simply upgrade your original SCT410. But there’s nothing like a fresh new kit that goes together like butter so pick up the SCT410.3 race kit and unleash it on the competition!

With the SCT410.3, we wanted to improve performance and increase value to the customer without increasing the price or compromising on the great qualities of the original. To do this, we went through the entire platform and made changes accordingly.

New rear arms feature the flat bottom but are also 4mm longer.
New rear hubs with reduced offset to match the longer rear arms.
New longer rear sway bar.
New clamping spring perches with captured shock boots.
New droop adjustment screws are now standard.
Results – lower CG, increased adjustability, increased stability, and increased consistency.

Weight, Durability, and other Improvements:

Lightened black anodized 4mm CNC chassis is now standard.
Aluminum pivot balls throughout.
Aluminum suspension and spindle bushings are now standard.
New lighter camber link rod ends and turnbuckles.
LCG Lightened Motor mount is now standard.
M5 stub axles are now standard.
Split center diff mount makes maintenance a breeze.
Lightened metal clamping 12mm wheel hexes are now standard.
Revised front bumper increases ground clearance.

As you can see, the changes are extensive and meticulous. This provides our customers with the best handling 4×4 SC kit that also happens to be the best value on the market.

Full Feature List:

Chassis:

4mm CNC aluminum black anodized chassis.
Super narrow layout – widest point is only 125mm (less than 5”) mudguard-to-mudguard.
Class leading front and rear clearance (short chassis overhang) provides better bump handling and jump landing.
Adjustable, LCG lightweight body mounting system fits most popular SC bodies (Losi, AE, etc.).
Lightweight, extremely durable front and rear bumper system.
Integrated battery tray/mud guard, battery is sunken into chassis for a super low CG.
Integrated electronics tray/mud guard for easy removal of electronics.
Spacious, enclosed, easy access radio box with integrated transponder mount.
Adjustable chassis brace system for fine tuning flex with front, center, and rear braces.

Motor Mount:

2-piece CNC aluminum motor mount with precision dual clamping gear mesh adjustment.
Split center diff mount for easy maintenance.
Lightweight direct-to-diff mount design.
Uses standard MOD 1 pinion.

Differentials and Drivetrain:

3 fluid filled adjustable super lightweight diffs.
Newly redesigned precision diff gears with innovative 1-piece cross-pin design for increased durability.
Less rotating mass = better acceleration.
Lightweight straight center driveline for maximum efficiency and reduced wear.
CV driveshafts with captured pins on all 4 wheels.
Standard 12mm hexes fits most popular SC wheels (SCTE offset).

Shocks:

16mm bore hard anodized shocks – Biggest-in-class!
4mm 7075 aluminum shock towers are standard.
Innovative conical piston design (not just tapered) provides varied compression and rebound rates.
Fully adjustable long travel suspension geometry maximizes stability and traction while providing superior cornering and on-power steering.
CNC aluminum threaded shock bodies.
4mm hardened steel polished shafts.
Triple guide design for true consistent shaft action.
Options for vented cap, emulsion, or standard shock configurations out of the box.
Optional springs and sway bars available.

Suspension and Steering:

Bulletproof suspension arms – thicker and stronger than the competition.
Adjustable front arm sweep and angle to make the car more aggressive (swept forward), or easier to drive (swept back).
‘Narrow pivot’ steering posts provide ‘0 bump’ geometry with almost 0 steering slop.
Adjustable hinge pin braces are standard (toe, anti-squat, kick-up, front arm sweep).
4mm inner, 3.5mm outer hinge pins, polished for smooth action.
Adjustable Ackermann and bump-steer (bump in, 0 bump, bump out).
Steering system is fully supported on precision ball bearings. No bushings here.
Straight rod ends and lightweight turnbuckles.

Other Features:

Exceptional wear characteristics. Leave the slop and warping to the other guys.
Easily adjust anti-squat, rear toe, front arm angle, front arm sweep, roll center, toe, camber, wheelbase, Ackermann, bump steer, suspension geometry out of the box..
Extremely easy to work on with minimal screw count.
Shares many parts with the EB/NB/ET/NT48 = less parts in your toolbox.
All metric hex hardware.
