Smilinbri's Tekno SCT410.3 kit build

[Smilinbri]

I finally started my Tekno SCT410.3 kit build.

The majority of my research was completed on the Tekno forum, and @bill_delong on there had the most knowledge to share. His build thread was precise, detailed, and had plenty of tips. Def helped me out a lot on my 1st kit build.

I decided to do something similar to his thread, in the hopes it helps some other newbies like me!!!

As expected, the Tekno kit is excellent quality and the build instructions are easy to follow. It's been a blast putting this together. The shock/pivot ball multi-tool def came in handy!!!

---

Bags A & B - All 3 diffs
This section was very simple. The diff parts were all perfectly created to Tekno's specs and everything went together easy. Once completed and filled with oil, they were smooth like butta! I was surprised that Tekno used composite diff cross pins though.

Upgrades completed:
10k/7k/5k Diff oil
Fast Eddy Bearings (throughout build)
Metal 44T spur gear-#TKR5115
Aluminum diff cross pins-#TKR5149A

---

Bags C & D - Front and Rear Gearboxes
This part was straight forward and super easy.

---

Bag E - Rear End
This part took me a while due to not understanding at first that the little pill pieces that go into the C & D (and A & B) blocks have a purpose. I was wondering why I had so many and what the little dots were for. They weren't braille. Their purpose is to adjust the rear anti-squat and rear toe. Took me a lot of research to determine how I wanted it tuned for my dirt track since that's really the only place I'll be "racing" it. Thankfully, I found an app from So Dialed that allows you to select the different dots to see what the results are. This made it so much easier! I ended up going with .5° anti-squat and 2.5° rear toe. We'll see how that goes. (App pic below shows 1.5° anti-squat, however with an aluminum C Block, you subtract 1°)
I found the suspension arms did not need much reaming. Instead of a drill bit, I used a 4mm saw chain file.
Upgrades completed:
Aluminum C and D blocks-#TKR5163 & #TKR5164

---

Bag F - Rear Camber Links
Had to pre-thread all the turnbuckles. Used a drill. I found this whole part was a PITA, but it got done. Using the drill helped, just had to make sure they were on correctly. Had to redo a couple, go figure.
Upgrades completed:
Aluminum clamping wheel hex nuts - #TKR5571A

---

Bags G & H - Front End & Front Camber Links
Same process as Bags E & F. Went with -1° sweep & 12° kickup.
Upgrades completed:
Aluminum A & B blocks - #TKR5161 & #TKR5162

---

Bag I - Steering Assembly
Not bad, except for the stoopid servo saver spring. That was a real pain. Tried multi-tool, plyers, wrench, vice clamp.......finally just used all my might with my palm. Lined up the screw cap and pushed on it until it caught. I was able to finally get it to catch and start screwing on. Thankfully, it was straight on, and I didn’t cross thread it. Placed the Ackerman plate on the far rear hole.

Upgrades completed:
Aluminum Ackerman plate - #TKR5100

That's it for now. Going to continue working on it today and will update my progress later. Peace Out for now!!!

The trick on the steering post is to screw it counterclockwise until you feel the threads snap into place, then tighten clockwise

Same goes for the shock collars too!

Your build is coming along nicely, looking good!

 

[Calabash]

Nice job! I loved building from a kit, at first daunting, but working bag to bag, and suddenly you are done, and so satisfying having it all come together. My hands hurt from all the wrenching when I did it.

Thanks Bill! That means a lot coming from you!!!

I saw that advice and tried, but for whatever reason didn't work for me.

I'm on the shocks now so will try again.

Bill, your build thread was top notch!!! I don't think I would have felt so confident on my 1st kit build without it. There's a bunch of peeps on Arrma Forum that agree too! You are def one knowledgeable SOB!! Thank you for taking the time to write all that up and for all your contributions to this awesome hobby!!! You are the man!!

Thanks! Appreciate that. Yea, it's just like a large Lego build. One bag at a time!!

 

[Smilinbri]

Almost finished!!!!

Bag J - Front End assembly
No problemo!
I did not use the 2 washers above the steering ball link for less bumpsteer.

---

Bag K - Center/Rear assembly
Easy peasy!!! Just don't forget to put the center driveshaft in before attaching the middle diff

Upgrades completed:
Aluminum split center diff mount #TKR5262
Added steel rear skid plate #TKR5031

---

Bags L & M - Front &Rear Shock assembly
Pretty straight forward. The "skewer" method recommended by Bill DeLong worked perfectly to get all the o rings and stuff in the shock. (Forgot to take a pic of it)

Went with standard build, 420cst-F/325cst-R, 2nd to outside holes on shock mount/inner holes on bottom

I will def upgrade to aluminum shock caps and adjustment nuts in the future. Those little pieces ain't cheap!

Just a few more steps!! So excited!!!

 

[Greywolf74]

allllllmost there!

Nice job. I don't know what I like best during "a build". Probably the shocks would rank up there as I love off-road RCs, and watching great shocks soak up nasty terrain.

Thanks for posting pics of your build. Because of you, I got to get me one of them Tekno skid plates.

I love my Connext1 driver handles. How do you like that Malco Connext3 ratcheting handle?

Thanks!! Appreciate it!

Finally finished the build last night (except painting the shell)....just need to get final write up done. Paying my March bills now...ya know...priorities and all.

I love em!! I have 2 long ratcheting ones so I don't have to keep changing bits. Also have a few other non-ratcheting ones. I feel like the Karate Kid in KK3 when I'm using the ratcheting ones like he did with the little drum thingies.

Got one ratcheting seperate and then bought this set.....

 

[Smilinbri]

Well, it's the final stretch and I have completed my build, except for painting the shell!!!

Started painting another one I got as practice since it's my 1st time and o boy, that didn't go well. Gotta finish that mess and will post in painting forum when I'm done. Def some lessons learned and more practice needed.

Bag N - Servo/ESC/Receiver
Def was easier with the wiring once the side trays were put on the chassis. Took awhile to clean up the wiring and the motor leads were really long. I don't/won't solder (could have shortened em), so had to determine the best way to mount everything so the wires could be neatly tucked away. I think it turned out pretty well!

Being Tekno and a SCT, which typically are known to be driven on dirt tracks, I was surprised that the receiver box was so open with holes and there wasn't a water/dust proof seal. I understand the holes on top are for a transponder and I believe the other slit was for some extra braking thingy.....I don't have a need for it. So I went the "manly" way and used duct tape!! Black Gorilla tape over all the holes. Put a slight bit of grease around the top edge before putting the lid on and then taped the edges.

I cut the tabs off of the ESC for more room and used double face tape to secure that down. In hindsight I should have left at least 1 tab on and drilled a small hole in the ESC holder and screwed it in. I foresee the ESC flying out after the 1st big crash. I'll deal with that when the time comes.

And ended up not using the Y adapter for the fans that you can see in the 1 pic. Just plugged em both directly into the receiver.

Electronics:
Hobbystar HBW-4724HV Brushless Servo
Radiolink R6FG receiver
Losi Tenacity Pro-Dynamite Fuze ESC-130A (from Jenny's RC)
Tekno 25T aluminum Servo horn #TKR5253B

---

Bag O & P - Final Assembly - Motor/Servo links/battery tray straps
Straight forward steps.

Motor/Upgrades:
Hobbywing EZRUN 3660/3200kv
17T pinion
Longer battery straps - #TKR40007K
Power Hobby aluminum motor mount
Surpass Rocket 30mm fans x2
Rear arm mud guards - #TKR5174
Air control guards - #TKR5504 - painted with Gun Metal-PS-23

Tires: Team Associated Pro4 SC10 on Fifteen52 wheels

Body: ProLine FLO-TEK Fusion (still needs painted)

I'll post the final pics of the painted body when the weather cooperates and I can get it done.

This was a pretty straight forward build. Only a few hiccups, but was a blast!! I tested it in my basement to make sure it runs. Can't wait to get it out on my track to see her rip!! I'll most likely tweak some of the adjustments once I run it a few times.

Thanks to everyone for following and I hope this build thread helps other newbies building this kit!!!

That looks great! I think you've been holding out on us. Naw probably just an idiot savant!
