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
I almost wanted to give this kit four stars, but it has so many other good aspects I couldn't do it. Had to give it five. It jumps, lands, turns, as good as you can imagine.

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.

Tekno RC SCT410.3 Competition 1/10 Electric 4WD Short Course Truck Kit
Finally assembled mine after buying the kit 4 years ago lol. The detail on the manual is insane. The build was challenging but not hair-pulling difficult. Just make sure you have all the tools ready. I hooked up a Savox high torque servo and Hobbywing SCT 4000kv motor from 4 years ago to my Tekno. This truck runs amazing. Used the 15T pinion included in my motor and it works like a charm. A lot faster than my Slash VXL without overheating using 2s Traxxas Lipos. Insanely tough truck. I haven't broken anything yet after 4 trips to the track. I've crashed it hard so many times and it keeps on running. The current discounted price of $370 makes me want to buy another one lol.

Tekno RC SCT410.3 Competition 1/10 Electric 4WD Short Course Truck Kit
Awesome kit. 1/10 scale SCT built like a 1/8 scale truggy. Great quality easy and fun build. No problems. I’ve built Associated B74,2, Losi SCT 3.0, and X-ray XB8 all great quality cars but this was the smoothest build yet. So far it’s been very durable.and handles great. When it’s time to replace my 1/8 nitro buggy I’m thinking Tekno all the way.

Tekno RC SCT410.3 Competition 1/10 Electric 4WD Short Course Truck Kit
I've built many RC kits and quite a few of them have been Tekno. The quality is very good. But, unlike the EB410.2, ET410.2 and EB48 2.0 (which were all excellent with the box stock setup) the box stock setup on the SCT410.3 is not so great. Tekno recommend this setup:


You need the following to complete this:

TKR6106 Tekno RC Low Frequency 57mm Front Shock Spring Set (Orange - 4.91lb/in) (1.6x9.0)
TKR6114 Tekno RC Low Frequency 70mm Rear Shock Spring Set (Green - 2.44lb/in) (1.5x13.0)
TKR6065 Tekno RC 16mm CNC Conical Shock Piston (4) (Blank)
Ø1.4mm drill bit
450cSt Shock Oil
300cSt Shock Oil
TKR8104 Tekno RC Steering Bellcrank & Differential Top Plate Set (Updated) use with TKR8100
TKR8100B Tekno RC NB48 2.0 Aluminum Ackerman Plate
TKR5545B Tekno RC Rear HRC Hub Set
TKR5165 Tekno RC V2 Hinge Pin Inserts/Wheelbase Shim Set
TKR5161 Tekno RC Aluminum V2 "A" Block Adjustable Hinge Pin Brace
TKR5162 Tekno RC Aluminum V2 "B" Block Adjustable Hinge Pin Brace
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.

What an awesome kit. Built on spec and performs incredibly and super durable. Powered by the hobbywing sct8 4300kv motor on 2s and is a pure racing machine. We race every Sunday on a friends track built in his backyard in clay and will be expanding to the Tekni 1/10th truggy next.

Tekno RC SCT410.3 Competition 1/10 Electric 4WD Short Course Truck Kit
READ BEFORE BUYING!! Not a good deal. Bought kit. Searched for setups. Every setup that i could use was with parts that are discontinued. Contacted Tekno, needing a clay setup. They gave me the new "base setup". Here is the problem. The new base setup is done with parts that arent in the kit. I totaled the parts needed and stopped adding once i hit $125. So for over $550, you still dont get a body or wheels, and you have a "base setup".

I would have to say that the kit build was very enjoyable. Nothing was missing and the manual was easy to follow.The only con. I have is that I purchased an air skirt for the truck and even though it was a tekno product,the lexan panels were cut wrong and wouldn't fit,so that sucked.Everything else looks great and I'm completely happy with the kit.

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.
