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.

Tekno RC SCT410.3 Competition 1/10 Electric 4WD Short Course Truck Kit
I wrote a review 10 months ago. I am going to write a new review a try to do a better job of what I like and dislike. To better understand the writer, I race 1/10th 2wd & 4wd SCT and 1/8th E-Buggy. I race 2wd spec and mod Team Associated and 4wd SCT Tekno SCT410.3 and the .2 buggy. I have 9 other trucks and buggies to choose from but this is what I have stuck with for now.

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.

Update 8/11/16:
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.

Tekno RC SCT410.3 Competition 1/10 Electric 4WD Short Course Truck Kit
2018 - My son has raced (aka. durability tested) this kit and it's held up well. Definitely need to tighten the 8 cap head screws (4 on each side) in the carrier / spindle regularly (aka. after every race) as they do loosen off as you run. 3 years later, still happy with this kit and we'll continue to run it.

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!

Tekno RC SCT410.3 Competition 1/10 Electric 4WD Short Course Truck Kit
Absolutely love this RC.. I started with a cheaper brushless Exceed buggy.. then an Arrma Granite. Both of those RCs are fine - great for bashing and racing around the yard.

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!!

Tekno RC SCT410.3 Competition 1/10 Electric 4WD Short Course Truck Kit
Exceptional kit. The best SC truck out in my opinion. The added weight is what makes this truck so good. It's a beast, built solid and well engineered. The diff screws everybody talks about being hard to get threaded in... Not an issue at all. They go together very easily with good tools. I don't understand why people can't get them in. Don't use power tools, build the kit by hand. I only have two gripes: #1 The center Diff Mounting brackets being plastic (kinda chinsey feeling). #2 The weird suspension set up that comes box stock with the truck. The spring rates & oil weights are kinda an odd choice (front is real stiff, and the back is very soft). Its a VERY quality kit, very durable, very race oriented, very easy and fun to build. I've built TWO so far, and I give this kit a solid "A". Tekno did a great job! Put a big nasty 550 motor in it! And plan on buying extra Pink & Green shock springs!

Tekno RC SCT410.3 Competition 1/10 Electric 4WD Short Course Truck Kit
This was my first Tekno build and I'm very impressed. Quality is amazing, everything fit perfectly without shims and manual is best I've ever seen. On the track, its sick. I used the specs for a indoor clay track listed on website and was almost perfect. Already had a few hard hits and kept going as if I hit a pillow. I'm a long time AE fan but after this Tekno build, I have a feeling I'll be looking at Tekno more.

Tekno RC SCT410.3 Competition 1/10 Electric 4WD Short Course Truck Kit
As of nov 24 2020 all I can say is this.
The kit build went flawless everything fit exactly as it should. The only thing I’ve found so far that I will change is the springs for the rear shocks are not stiff enough for my liking and should have come with something similar as the fronts for spring rate.
I have yet to run it as I have no indoor tracks near me and outdoors is out of the question with over a foot of snow.
All in all quality and fitment of parts is excellent. As is the service a-main Provides

Tekno RC SCT410.3 Competition 1/10 Electric 4WD Short Course Truck Kit
Good lord this thing is a beautiful beast. The build was smooth the quality of the parts is outstanding the performance is mine blowing. I put this on the track for the first time and all the other racers we’re coming up to me asking what it was because it was so smooth and fast. The shocks are incredible keeping the car planted even on the rough outdoor dirt course that I run it on The stock set up from the instructions works very well are the small size track and I’m on I think there’s a little tweak here in there I can improve the performance even more but right out of the box It’s an absolute dream. I will definitely be looking at more Tekno vehicles in the future. My first race with it I took second place and would’ve had first but my fan stopped working so I had a thermal shut off on the final lap. As far as short course trucks go this may be the king. Buy it and never look back.

Tekno RC SCT410.3 Competition 1/10 Electric 4WD Short Course Truck Kit
Haven't ran kit yet..... waiting on pinion which didn't come with kit. Thats about the only complaint i have with the kit. Every thing whent together without any major problems. The only problem i found was shims for steering blocks dont fit.... not a real problom at all. I just left the shims out, it shouldnt cause any decrease in performance or strength. Plastics on this kit are some of the highest quality ive seen, no stripped screws at all no matter how big or small. All the hardware is oversized and looks very tough. Pretty sure this truck will be spectacular!!!!!

The build was good had a package I believe letter m had 2 extra screws in package. I did not use the factory shock washers I used the upgraded Delray shock washers also added the plexiglass guards to the frame. Have yet to run the truck on the track.
