Shayen RC Enthusiast. I happen to have them all out of vehicles at that time.....thought I would share. I never really knew there were two lengths of 1/8th scale about a year ago....

Darksharkracing Good deal!

TOJO RC Thanks TOJO

Ruben Robles Anytime!

Unfortunately illegal

RcNickster Hey Nick, the SCX10 is such a versatile platform, and with the right upgrades, can easily take on brushless power. Having been bitten by the Axial bug, I have an SCX10 headed in to The RCNetwork to begin a new project. My plans include dropping in a Tekin Roc412 - 2300kv with a RS Gen2. You can find the combo for right around $200 at all the big places, maybe less with coupons......The nice thing is you can control the speed/torque by what battery you run. For huge torque and crawling, use a 2s....want faster than walking speed for G6's - use a 3s....lastly, the motor is 4s capable, but the RS is only 2s/3s - Add an RX8 Gen 2 to run 4s for blistering speeds (for an SCX10!) The main thing, is you will be running a sensored setup, so you'll have buttery smooth throttle control. Hope this helps

It sure does help me out..... I am a fan of the "buttery Smooth" control myself lol. High speed ? not so much. The G6 kinda feel...really appreciate ya taking time to respond. Thanks so much...

I recommend the tekin t8 whatever mc you like 2200kv to 2800kv

Thank you kind stranger Cooldibs

2cwik4u104 The 2200kv is the larger canned MM motor....With that, which car are you putting it in? Specifically what weight? I'm not sure you'd need the larger 4038 Tekin can, since they offer a variety of kv options unlike Castle. As an example, you can get a T8 from 1400kv to 2650kv, or 6 different kvs.

ive never weighed any of my cars. I run it in an ALL aluminum rustler (106mph), guessing close to 12lbs and a stock gtp2e (121mph). guessing around 9lbs.

I had both. Have the 4038 2050 kV in my losi lst. Has tons of power. I can crawl with it if I want to. Castle maybe has a bit more punch. But I manage to break my rear diff all the time with my tekin on 4s so don't think it its necessary

Johnny Davis the Pro4HD fit with only a few mm to spare (remember the sensor wire). Check the size differences on the T8 and Pro4HD and see - the Yeti won’t be able to take much on that T8 though. The driveline will start deteriorating quick on that torque.

Jack Mcmurtrie I think you’re looking at the wrong type of motors.

Glad to help out!

Flash Hobbies Yep. The Pro4HD will have more torque overall, and run cooler than the Pro4. It all depends on the weight of the rig you're building.

Thanks for the info, the rig i'm building now will be about 13lbs

+Joseph Bones It will bolt in......but double check the length of the current can of your motor vs the 4038. The 4038's are 77mm in length and the 4030's are 69mm in length.

Thank you sir, I am looking to upgrade my Bone Stock Summit, (Going from Brushed to Brushless) and I understand that there are a lot of different motors out there, I am trying to learn more about the Motors.

+Joseph Bones The Tekin motors have raw power and are super smooth. You'll need the Tekin RX8 Gen 2 ESC to power it the best. It's a great system overall and is sensored - which means it is really smooth and efficient even at very low RPMs. Most cheaper systems will be sensorless and will have "cogging" issues at low RPM if you plan to cral at all with the Summit. Other than that, you'll have to plan on a kv that will suit your driving style.

Thank you again for help..

MAybe the smallest size (540) but you'll have to check the specs of your truck and if the motor mount will allow it to fit

Darksharkracing Do you have reverse engaged on the ESC settings? If so, does reverse seem more powered than forward? If it does, reverse your radio settings to reflect the opposite (if you pull the throttle, it should go in reverse...) Then, go into the Hotwire app and manually reverse the motor. Not sure why this happens, but I had an issue with my set up from my Axial Yeti XL - Might be the way the motor faces on the chassis...

+Donkey Commander the RX8 will run much smoother and be able to control that motor better - about 4 years ago, I tried saving a buck and partnered the Pro4 4600 with the MMP and nothing but heat issues from day one. No matter the gearing or battery, the ESC was clear over 175 most of the time. I installed the RX8 and it never hit above 110.

Honda TRX04 yeah

Tekin Pro4HD 3000kv. It's what I ran in mine

It’s a 2000kv….but I only ran the Yeti XL on 4s. It had plenty of power

@@TheRCNetwork thank you for the reply. So if I switch to the 1350 will I only be gaining torque on 6s?

You have a wraith that's 20lbs?? My fully built Wriath from Mattzilla - literally every part is aluminum or steel weighs in at about 10 lbs, or just shy. I don't think any 540/550 can handle 20 lbs. After all, most 540's are meant for 5lbs-7lbs and 550's usually are for the heavier SCT's/Crawlers at 7-10lbs

@@TheRCNetwork yes it's exceedingly heavy hence the 4pole 8th scale motor, it has performed beautifully till I failed to do my after snow maintenance. Gearing is 29/80 /built trans/ OD r&p front UD r&p rear, 5.75"/5" tires . On 2cell it has comprable speed to the stock 27 t ,3cell is comprable to a 3600kv w/ 12/80 3 cell

@@daviddroescher Honestly, I'd keep the 1/8th scale motor in there if it fits. Drop your gearing down and run 4s. I'm surprised you haven't puffed 2 cells on that combo/weight. Even 3cells would be challenged moving that weight.

@@TheRCNetwork kzfaq.info/get/bejne/ob6fl5uf2NeaZp8.html Hears aclip of it on sun rise mountain in Las Vegas. My wheels are 4oz ea +48oz led weights. There is 5lbs in just the wheels.

Thanks Pete!

The RCNetwork do more. I’ve learned so much more about this hobby from videos like this. How about a soldering video. An actual solder, from tinning the tip and soldering contacts to soldering a battery wire to a connector

John Smith most manufacturers (like HobbyWing) use 4 digit numbers like that. 36 would mean the can diameter and the second would be the can length (without the motor shaft). For HobbyWing, a 3660 is a 550 sized motor. Their 3652 is a 540 sized.

@@TheRCNetwork cool thank you! I'm trying to find out if I can fit a 3670 to my stampede so the diameter is the same but just longer than a 3650 correct? Thanks

John Smith it should be....check the manufacturers spec sheet for the motor. They should list diameter and length

@@TheRCNetwork thanks 👍👊

I haven't seen it, if it does.

Ok. Thanks for your feedback.

tylerfigs Really tough pricepoint for an 1/8th scale system that's decent......Maybe check out a HobbyWing....My local shop has this for $254 and includes a program card....www.nitrohouse.com/Hobbywing-Sct-Pro-Combo-Pack_p_17486.html

i was thinking a ezrun system but i wanted you thoughts on it

tylerfigs Also good, from what I hear

The RX8 Gen 3 and the T8 1900 from Tekin - bolt right in and are a great combo

The RCNetwork cool thanks, also which servo, pinion gear and batteries should I use? Sorry for all the questions I’m new to the hobby.

Ramiro Prado servo wise, get something with at least 300 oz/in of torque, and about .10 seconds or less. Pinion - start with a 15t to start, it really depends on your track/terrain and how much the buggy weighs.

Ramiro Prado and you’ll want 4s 5000mah Lipo batteries. The GensAce versions are what I use

It will only need a 540 sized motor, and I would stick to a 17.5t

Not even close. The 2850 is a 540 sized motor - although its a lower kv and capable of using from 2s to 4s, it doesn't have the torque to push around heavier vehicles like the T8 does. The 2850 has a 3.2mm motor shaft, vs the 5mm of the T8. The T8 is just a larger motor over all, intended for 1/8th scale applications and can push heavier loads. It really depends on what vehicle you're putting it into.

my buddy has the tekin in his 6th scale custom trail truck and the castle is in a scx10 i was just curious if hes still gonna be faster lol

The Tekin system can push around more weight of that 1/6th scale....the SCX10 only needs a 540 sized motor. Being fast is all about a mix of kv, gearing and voltage - but in an SCX10, it's not about speed, unless you're racing U4RC

The RCNetwork no just screwing around on the trails making rooster tails with mud just having some good ole fun with some speed if I want lol

Look at the new ROC412 HD from GTekin. It's now element proof and has tons of power....even down to the low 2000's in kv

Thanks Flyin Brian

A direct fit would be the Pro4 motor - maybe the 4600kv - it should bolt right in....but you'l need an appropriate esc to handle that motor and a pinion with a 5mm shaft

@@TheRCNetwork i found a firma combo with a 3300kv motor. Same size and everything. 3mm shaft so it should fit the gear. what you think?

There's a range for both. 4030 is buggy sized and 4038 is truggy sized

There's possibilities out there....but you'll have to deal with pinion shaft size/pitch, etc when putting in a replacement motor. MAke sure you check. Check out my Mini 8ight T video series, where I go over possible motors for the 1/14th siaze vehciles: kzfaq.info/sun/PL5_p3gwitPIk2mrxxXz8vnumV1H5f6sxt

Thx will check it out right now. Do you also know how to make my car immediately shift from forward to backwards.😉

Yes, for the most part

The RCNetwork Thanks:)

I don't think 550 is even allowed in 4wd buggy.....plus, it would throw off the balance. 540 is plenty.

+The RCNetwork I was actually just in tower hobbies n realized that the redline gen2's are not available because they are being replaced by these black Gen 3's have any experience with redline Gen3

+Jonathan Postell II I have one on it's way to me....it will be going in my D413. I honestly haven't read the specs yet, but I'm sure it's lighter and more efficient with more cooling vents

+The RCNetwork nice I'll be ordering it soon as it's back in stock, thnx for the replies and keep up with the D413 updates luv them

+Jonathan Postell II D815 build next???

Most of Tekin stuff is price protected, so your best bet is a shop like Amain that you can use a coupon

RC Johnny Thanks Johnny!

mtctookie25 Thanks MTC!

Sounds good!

Thanks for stopping by!

If you're looking for "industry standard" that's definitely not RC! Motor can sizes are all over the board.....like you saw in the video - 540 and 550 can sizes are common in 1/10th scales. I've seen it referenced once by Team Orion where they call 1/8th scale buggy motors (thee 4030 T8 by Tekin) a 690 can. Usually for 1/8th scales you have to rely on kv and can size in mm. Sorry to confuse you, but it's like clarifying muddy water, TBH

Also, Tekin references the two different T8's as 4030 for buggy (69mm can) and 4038 for truggy (longer 74mm can)
