This is the Tekno RC SCT410.3 Competition 1/10 Scale Electric 4WD Short Course Truck Kit. The SCT410.3 is an updated version of the original SCT410 with a slew of updated parts and improvements. The SCT410.3 leapfrogs over the 4×4 SC competition in terms of performance, durability, and value. Tekno RC has their customers’ best interests at heart so there is a clear path to simply upgrade your original SCT410 if you already have one. But there’s also nothing like a fresh new kit that goes together like butter!
With the SCT410.3, Tekno 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, they went through the entire platform and made changes accordingly.

First, I'm going to start with dislike.
1) The composite cross-pins in each diff. I use aluminum.
2) The stock set-up. I know by now everyone knows the stock set-up is crap. If you are nose diving and you are close to stock, its probably from chassis slapping the rear of the truck.
3) I have very precise scales and the truck is off balance with a Tekin 4300HD motor, RX8 ESC, Protek 150 servo and a Trinity 7150MaH 100C battery. You need approx. 38-45g in front of the servo and 60-70g just in front of the shock tower on the batter side.
Second, what I like.
I like most of everything else on the truck. I would have liked to have seen the aluminum hinge pin holders A,B,C & D along with aluminum diff cross pins but in my opinion, they do not slow the truck down.
Final thoughts and set-up.
My shocks are built with 8x1.4 tapered down pistons. I am using 32.5 wt AE oil in the front and 30 wt AE oil rear. I feel the truck has a high roll center and made all of my camber links longer. I only run 2 degrees of anti-squat and it jumps better and obviously handles bumps better. I run full rear toe in and 1.5 degree front toe out. It works for most tracks without changing anything.
I am still running 8 x 1.4 pistons but I have increased the oil to 40 AE front, 35AE real and pink springs both front and rear. The previous setup is too soft and allows the truck to transfer weight too quickly. This new setup does not throw the weight to the front coming off power and visa-versa. I truck jumps very flat and the dampening is very good for virtually all indoor tracks at least as a starting point. IMPORTANT: make sure you do not run bump steer with this truck. You can check by holding the truck up in the air with the tires off with the A-arms flat and find something that is parallel to the outside of your wheel mount (Stub Axle). Pull the A-arm to compress the shock and the wheel mount should stay on the same line. If it moves inward, you have positive bump steer and out is negative. You can change it by add/removing washers under the Ackerman or at the steering spindle.
Also, It seems to be best not to run more than 2* of anti-squat as the truck wants to nose dive at times.
I know its a lot to read but I hope it helps.
2015 - Excellent kit from Tekno! Parts quality is very good and the build is super smooth with easy to understand instructions. Would be nice to have the option of a higher priced 'team' version of the kit that includes the optional upgrades (i.e. aluminum diff cross pins, aluminum hinge pin braces, etc.) so you wouldn't have to get the parts separately. Overall, excellent! Highly recommend this truck!
What separates this is the precision. The way it turns, the balance, the way that it claws for traction. I absolutely destroy his Slash around a dirt track despite the fact that we are neck and neck in a straight line.
Building this was tough - when they say it isn’t assembled, they mean nothing! From the steering linkage to the diffs, to the shocks, you will learn what is behind every piece of aluminum and plastic. Totally worth it!
The A arms are twice as thick and sturdy as the ones on my Granite (which is known for toughness)..
Couldn’t be happier! Great product from Tekno!!
The outer tie rod bolt heads rubbed the rims, so I replaced the factory socket head screws with button head.
The lower shock tower bolts were a bit too long and hit the heads of the chassis brace bolts, so I once again turned to my bolt bin and used slightly shorter bolts.
The front springs are too long. The front ride height was terribly tall even with the spring collars adjusted all the way up.
And the washers/shims that go under the steering stops would hit the steering arm. So I slid two washers stacked together under the side of the head of the bolt and tightened it until the shims slide under the bolt nice and snug. Now I keep track of the amount of turns in or out to make and changes.
I used the generic off road set up from the Tekno website using orange front springs, green rear, etc., and it turned a race winner into a dominating beast!!!
This thing is tough. Needs nothing but a little suspension tuning stiffening the shocks and springs.
You need the following to complete this:
TKR6106 Tekno RC Low Frequency 57mm Front Shock Spring Set (Orange - 4.91lb/in) (1.6x9.0)

TKR5163 Tekno RC Aluminum V2 "C" Block Adjustable Hinge Pin Brace
TKR5164 Tekno RC Aluminum V2 "D" Block Adjustable Hinge Pin Brace
I also purchased these:
TKR8702 Tekno RC Aluminum Shock Caps (2) (Emulsion/Vented/Non-Vented)
TKR5504 Tekno RC SCT410 Air Control Guard Set
TKR5253B Tekno RC Aluminum Single Sided Clamping Servo Horn (25T)
The camber link and steering link lengths specified in the manual are totally different from what this setup requires.
I raced this kit for the first time today and I'm very happy with it. The only reason I'm not giving it 5 stars is the fact that you have to purchase so much extra stuff to make the setup.
Have done zero maintanence too it for the past year and still runs ok.
