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
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
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
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
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!!!!!

First Tekno kit. Excellent. Great instructions and a pleasure to build. Have also built Kyosho and Losi kits but this is my favorite so far. Converted this into the DB48. Rock solid and well designed chassis and quality parts. Now I know why everyone raves about Tekno!

Tekno RC SCT410.3 Competition 1/10 Electric 4WD Short Course Truck Kit
I've been bashing RCs around for about five or six years now. I've owned a lot of different kinds of RCs and gained a lot knowledge. But even though I took several slashes out to the track over the years, I never took racing seriously.

I took a break from the RC world for a while, and wanted to get back into it. I had sold off all of my old RCs and so I bought a Slash 4x4. I bought the center differential. I bought the LCG conversion kit. I tried to tune it. Bought all the spring kits, tried all the online setups, different shock and diff oil weights, different shock builds, nothing I did made it drive the way I wanted it to.

So I decided to take the dive and buy my first kit RC. When I opened the box what I saw was daunting. I was relieved to find that the instructions were extremely clear for the most part. My instruction manual had an arrow pointing to the wrong hole for the rear chassis brace (it goes on the opposite side as the others) and one of my bags had two extra very short counter-sink screws that were not accounted for in the instructions. But other than that everything was extremely clear and easy to follow.

After I got the roller built I put the RX8 GEN2 from my old Sportwerks Mayhem E-Buggy I converted in it and bought a Tekin Pro 4 4600kv and a Savox SC-1267SG servo to drop in. I upgraded my transmitter/receiver from the Traxxas TQi system to a Futaba 4PL and a Futaba R2104GF receiver.

After setting the RX8 GEN2 up for 2s and 7.2v BEC I ran a couple of packs through it. The stock rear springs are extremely soft and required 3/4 preload just to keep the rear end off the ground. My local hobby shop suggested red springs for the rear which let me reduce the rear preload to just 3-4 turns in the rear.

I ended up with my ride-height just a bit higher than what the manual states, but the lower control arms in the front and rear are both level with the chassis, which is usually what is recommended. A bit of fiddling with the turnbuckles to get everything aligned, re-dialing in the steering trim, and getting everything driving straight and true was also very helpful.

After that I ran about 2-3 packs through it and was amazed at how well it handle. It absorbed the rough stuff easily with still plenty in the suspension to support the truck through the turns without digging in. Throttle response is excellent with little to no loss/lag in the drive train. Motor temps were about 160F and the ESC was around 76F after 10 minute runs on a 16t pinion gear so I swapped in a 15. I had the tuner specialist in the shop dial down the punch on my ESC to help with the rear tires spinning when trying to get on the throttle out of turns and my temps evened out to ~118F on the motor and ~98F on the ESC so I know the system is happy, and the control is still good.

Being that I am not a pro, needless to say I have crashed this many, many, many, MANY times. The brand new slash body I put on it (I had it laying around, it's a nearly perfect fit for this kit) is nearly destroyed, while the kit itself remains mostly unharmed. I highly recommend skid plates for practice sessions to help save the chassis if you are an unskilled driver like myself as that seems to be the only part of the truck taking wear at the moment. Even the front bumper is still in immaculate condition considering the pounding I've given it.

I did manage to land out of a huge jump directly into a massive nail holding down some of the track pipes during a run. As I limped it to the side of the track with one of the front wheels perpendicular to the car I feared the worst. However all I managed to break was the A-Block, nothing else was bent or broken. The sway bar link had come out of its ball joint, but a new A-Block and 5 minutes wrenching and I was back in action. I splurged and got the aluminum block, but honestly if that's what it takes to break the plastic one it's probably more than fine.

With the help of the pros at my local track I've managed to get it dialed in and am now enjoying my wheel time immensely. I can't wait to get good enough to start racing, but I can already keep up or go faster than a lot of people running 1/10th scale.

All in all I am extremely happy with this kit, and if I decide to go 1/8th scale buggy I'll be getting the EB48, which is exactly the same as this kit with 1/8th scale buggy trimmings!

Bought this truck as my first tekno and i have to say oit of all the kits ive put together this is by far the easiest and most fun except the turnbuckles. I will be buying another tekno soon and cant wait to build another. I upgrades a few odds and ends. Stiffer and longer springs aluminum servo horn 1/8th scale wheel adapters mostly small things running on 3s with a hobbywing pro sct sensored and its screaming fast. Its also super stable and jumps well running stock fluids at the moment except for the grease is a heavy duty blue grease i get from work of much higer quality than normally used in rc and automotive products.

Tekno RC SCT410.3 Competition 1/10 Electric 4WD Short Course Truck Kit
If you want a write Short Course Truck to start it off, buy this. Don't waste your money on Traxxas Slash or other Associated SC10 stuff. This is what you want to get. Trust me, Been there done that.

This car will handle extremely well stock. Race ready is an understatement. The center differential really helps put the power down evenly so the car would not flip over. The durability is unmatched to any other brands.

However, I recommend few upgrades for the future.

MUST: Hardened Steel Spur gear

1. Aluminum Hinge Pin block set
2. Aluminum Servo Horn
3. Aluminum shock cap and delrin cartridge set with TiNi Shaft
4. Blue Spring in the rear
5. DE-Racing skid plate
6. M2C rear chassis brace
7. Aluminum Cross Pin for diffs

Tekno RC SCT410.3 Competition 1/10 Electric 4WD Short Course Truck Kit
Got my kit 5/21. Instructions are super easy to follow and the kit overall was very easy to put together. I have not had a chance to race yet but from the looks and feel of the truck it should be very durable. The one recommendation that i have is to try to tap some of the screw holes in the diff cases. I stripped a few screw heads and the hexes become slots. Some of the camber links can be tough to thread. But all the hard work will be worth it when its finished because you will have the most durable, best looking ride at the track.
