- I sorta made a promise to a few people that I would make a video showing the install of an Integy Spur Gear.
The following list is of gear combos and the top speeds I achieved:
"FT"= Full Throttle
Arrma Typhon -Toro TS 150 esc - Poseidon 2200kv motor
29T/46T Team Durango Spur - 89mph on 6s 60c 5000mah "FT"
29T/38T Integy Spur - 96mph on 6s 60c 5000mah
Arrma Kraton - Castle xL2 esc - Cordova 1440 2000kv motor
30T/40T Integy Spur - 76mph on 6s 60c 5000mah
30T/38T Integy Spur - ? Haven't tested this combo yet - เพลง

Of all that I am subscribed you are the best
:-) Thank you!
Lol tools speaking from experience I believe my friend u know exactly what ur doing, thanks for Intel on how to change
Chris Cosey Thank you! My pleasure!😄
Ok I'll try that rite now thank alot
Jovan Joseph No problem 👍👍
Thank you
edwin acevedo You're welcome 👍
Good job bro nice video my gasket does the same thing on my kraton it stays to the spur gear instead of being on the diff cup
RCJer Thank you! Those gaskets do get pretty tricky sometimes.😄
Thanks for doin the vid Dave I learn a lot. I knocked my pinion loose after a very rocky gravel bash.
I also struggling getting a good mesh its always stiff after you start tightening everything down.
Bartholomew Slobodzian No problem...My pleasure. I know exactly what you are going through when tightening down your gear mesh. I'm not sure which rc you have, but Hot Racing sells a new style motor mount that takes all those mesh problems away. I have a video on it too. It's the Hot Racing Channel Lock Motor Mount.

I got a senton dave so I should be good I will look it up thanks
You're welcome!
Hi mate I've been looking for a smaller spur gear for my kraton 6s I fitted the 8s motor and ESC and that smaller spur will help with getting the speed back up. Try some bearing mount for your bearings just incase the bearing starts spinning on the spur gear it will do some damage. Thanks for spur information brother 👍👍😷🤪🤣🤣🤣
Thank you!😅👌 My pleasure!😀👍👍
Thanks a lot I'm doing this to my brand new arrma talion I'm going to take everything out clean it and I going to make sure everything is sitting right ...i did it a couple of time but wen I screw the screw tight it locks up but thanks I'm going to keep trying..
No problem.. Glad I could help!
Good job my Brother but I use plastic tweezers are wood toothpicks when remove rubber seals and gears to keep from cutting or scaring them. Just a tip.
Thank you! That's a good tip. I was being a bit of a MacGyver using what was in close proximity at the time to cut down on camera time... lol... but now that you've said it, I need to put a set of tweezers in my tool bag! :-)
Have you got the new arrma blx motor or esc in any of you mr cars
If I'm not mistaken, Yes. After my Kraton caught fire, I sent it in to Arrma and when I got it back among the things that were replaced was the motor and esc. It originally had the red motor and red esc, but now it has the black esc and the motor has a totally different color scheme.
The link below is it in action:

Hi Dave good video, I'm having the same problem as j j it get all stiff wen I tight the four screws it gets lock up doesn't want to spin I'm trying 38t 29t pinion..u have any suggestions pls let me know...thanks.
Jose Lopez I did a 96mph run with a 29t pinion and 38t spur in my Typhon. If you have already cleaned all of the inner parts of the center diff, filled it up with fluid, and it's still doesn't spinning, I'd suggest taking it apart again and when putting it back together make sure each part of seated properly in its slot. The sun gear on both drive cups have to fit perfectly on top of the pin that holds the cup shafts in place on the diff. Before closing it and screwing it back together, spin the drive cup with the open side of the diff facing up to make sure all of the gears are meshed and seated properly before screwing it back together. Again, make sure the sun gears are seated on their pins perfectly. There's a notch on each of them that the pin slides into.
The new talion v3 the diff comes w shims aready and I made sure that the ends things that
are in the gear are sitting all the way down and it turn w no problem but thanks I'm going to work it out..
I forgot to mention about the two sets of gears that sit on top of one another; there is a certain way they sit on top of one another too. You have to make sure the notches on each touch one another so it'd sit perfect. As you see, any slight millimeter in any direction throws the whole functionality of the diff off.
Im running the kraton v4 I have good fan with a 16t pinion for 66mph. Question with the stock moter and esc what gear setup can I use and keep my temperature down for more speed?
Gerry Little Unfortunately when doing speed runs, heat is always going to be an issue. A 16t pinion is the highest you'd want to go for all-terrain driving. Anything over 17t I would keep it on hard pavement to prevent heat from the heavy load on the motor/esc from riding off-road.
I hope that helps!🙂👍
@@TheDeterminedFisherman is a 14t good for my arrma kraton 6s v2 for bash and off road With stock spur???
What all did u have to do to get that spur gear on cause i went out and got one but doesn't fit properly?
killaharl III Honestly I just screwed it on as if it were stock, but what I didn't know until recording this video is that shims are needed to prevent the spur's screws from rubbing against the motor mount. If you fast forward and pause the video at the 18:30 mark, you can see the rub scratches. I couldn't tell the Spur was rubbing while running it, but the visual marks on the mount makes it very evident.
I put the 42t in mine and the neck of the drive dog shake bad under acceleration
hi
is the centre hole diameter of this spur gear that you are using fit to the arrma ?
because the center hole of the arrma seems smaller
thanks for the help :)
Hello..... It fits onto the stock center diff, but the overdrive shaft of the spur is a tiny bit wide, wide enough to allow the screws holding the spur on the center diff to rub against the motor mount. The easy fix would be to at add few washers/shims between the spur and the motor mount. I honestly didn't notice the rubbing while running it, but you can see it on this video at the 21:53 mark. I reached 96mph with that center diff setup in my Typhon rubbing and all.
13djdave13
thanks my friend for the reply and for the good info :) nice viedo men
Clinton Mangion No problem👍👍
Did the 38t spur lock the diff? I tried it and the diff seems to be locked.
No, but I think I know what happened... After running this 38t spur gear many times, I noticed that the motor mount/center diff had scuff marks on it and it was coming from the screws that held the spur gear on to the center diff case. A good way to eliminate that would be to replace the center diff with a spool, but with a spool you may run into heat issues and it is not recommended for off road use.
The integy looks like 6mm bore, but arrma cups 5mm, did u usea reducer?
I ran it for a long time by itself to later realize the screw holding it on was scrapping the motor/diff mount. I was able to do several speed runs and when I went to change the spur is when I saw it. It fit the center diff case and I've used them on the Raw Steele Spur adapter.
@@TheDeterminedFisherman cool, im looking for a spur to fit typhon, anythingupto 46t even
Great work man. I did not know you could use the integy spur gears on the outcast or kraton. Is it still 42 pitch with 38T? I was just wondering if you have to change the pinion pitch.
Thank you! Actually with Arrma's 1/8 scale line up, all of the pinions and spurs are "Mod 1". Usually gears that have "pitch" in the name are for 1/10 scale or smaller. 1/5 scale rc's use "Mod 1.5" which is pretty thick and heavy duty. That's what I used on my 1/5 scale gas to electric conversion.👍
@@TheDeterminedFisherman thanks for the info! I bought a new pinion yesterday and put it on. Now I just have to get the diff rebuilt. You really helped me out man! Thank you
i guess Im quite randomly asking but do anybody know a good site to stream new movies online ?
@Kingston Douglas flixportal xD
@Jeremias Justus Thanks, signed up and it seems like a nice service :D I really appreciate it!
I tried putting the 42t on my arrma typhon but it got stiff and wouldn't spin it lock up is that normal or probably the diffs ar different can u tell me where I'm going wrong
When taking putting the diff back together (I'm not sure what they're called) there are 4 metal pieces that go between the 4 inner gears that are turned by the 2 sun gears. They must be positioned so that the flat side is facing towards the side of the spur gear which should make it sit flush with the plastic diff case. If that doesn't solve it, I'd suggest taking the whole diff apart, cleaning it thoroughly, put it back together, and refill it with diff fluid of your choice. I actually had the same thing happen to me once too. Just have to make sure that everything is position how it originally was prior. I also noticed the screws in the spur rub against the motor mount as well, but somehow never noticeably affected the smoothness of driving.
That's what happened to me. What did you do to resolve the issue?
Looks like that spur gear was made for it. Stock spur seems huge
Chris Chupp I hear ya. The only problem is using a smaller spurs creates more heat. These Integy spurs fit, but also unnoticeable rubs a little on the motor mount. It could use a few shims between the motor mount and the spur's out-drive shaft.👍
I got it to work but the rear cup is leaking diff oil is there a way to fix that
Make sure not only the rubber O-ring is in place, but also that the sun gear is seated on top of the retaining pin that goes through the shaft of the diff cup. There's a little notch etched out where the retaining pin fits into on the underside of both sun gears.
I want to see that speed run, with that setup.
I just got my Talion.
About to go hangout with #MINIHEAT from facebook.
Nice Vid bro.
Thank you! I actually have the speed run video of that setup here: th-cam.com/video/S-wor5Ycfqc/w-d-xo.html
I also swapped the 38t to a 34t so now the gearing is 30t/34t. So far I've topped out at 86mph and 87mph. Hoping to get a better run in someday in the triple digits :-)
U need a high speed alignment my friend or like a little steering stabilizer or damper
Chris Cosey I eventually learned that the Arrma Typhon was a better platform to use for speed seeing that most other Rc's weren't so stable.
Trial and error was fun though.
😅🤙 🏎💨💨💨
What's the top speed with ur set up
87mph with the Kraton so far using 30/38 gearing on 6s. Video below:
th-cam.com/video/S-wor5Ycfqc/w-d-xo.html
Its a proses swapping these spur gears, but do you get any leaks between the shaft and the bearings? Cuz the way I did my Typhon 38t spur I cut off a 5 x 11 gearing in half and used the center of it and put that on the spur gear plus a new gasket and no leaks at all out of it...
I haven't had any big problems or messes with leaks. After a few runs I get the usual sand particles on the chassis, but the diff fluid is still at a good level inside the diff when I go to switch spurs. Possibly because I use very thick fluid? I'm not sure, but no problems though. Just dropped it in like as if it was a factory upgrade with no modifications. I did notice the screws on the diff brush against the metal mount slightly, but not enough to impede the ability to drive it smoothly that I've noticed.
R/C CUSTOM
What do u mean by 5x11 ??? Mine leakes a lil to to much play between the shaft arear that gos threw spurr
Your sun gears don't have the washers behind them. They act like a bearing for the sun gear to turn on for front axles wheels...
Mike Fahner Thanks! A while ago I was always wondering what people meant when they talked about using shims, and then I finally figured out that shims were just very thin washers. Lol
That's an accessory that I've yet to venture into besides using the copper washers I've used for my spools.
How did you deal with the spur 6mm diff hole, the kraton v2 is 5mm..lmk thanks.
After several runs, I finally noticed that the screws were bumping into the motor mount. Strangely, I didn't see it until I went to swap out the gears.
So to do the spur swap you need order 6mm screws??
Yeah iv been wondering that...been trying to do the same mod but it's no good...unless I can put one of the 6mm outdrive cups on the spur side, but no doubt the pin hole or something else will be a different size....
Will the 38 spur work on the arrma Typhon
Yes... it's the Integy 38t HPI 1/8 Apache SC & C1 Flux Dessert Buggy Spur. It fits the stock center diff and it took me to 96mph. It will also make your esc and motor heat up. Off-road use is not recommended if you install it, on-road only!!!! You might also want to put shims between the spur and and diff motor mount to prevent rubbing although it didn't noticeably cause trouble while running it, there were rub marks on the screws and motor mount.
13djdave13 thanks
no problem!
You think this would work for tge 46??? Cant fint the team Durango aby where
Yes, for both Kraton and Typhon and if I'm not mistaken, maybe even the Senton and Talion too.
I installed that spur on my Typhon and got 96mph. The only bad thing that happened that was that the screws that hold the spur onto the diff rubbed against the motor/diff mount a little leaving marks. This video above shows the marks I'm talking about at the 21 minute 40 second time mark of the video. I couldn't tell I was having that problem and I believe it had the capability to achieve more than 96mph if it wasn't rubbing. Some people said to add shims to keep it from rubbing and wobbling. Here's a link to a run video I used it in. th-cam.com/video/iTb1mlvi4cg/w-d-xo.html

Awsome good to know ima order it today...thanks for the help also is there any where u can buy extra gaskets ...?
Im still on stock esc and motor but want to get the most out of it befor i swap...
Will it matter if i change only the middle diff fluid when i swpapp the spur?, also what the best ratio for diff fluids
Front
Center
Rear...
I spent almost 700 on my 7s typhon and charger i dont want to damage my investment lol ...!!!
Btw thanks for help and advie great videos too
No problem. Thank you. I feel you on not wanting to mess up your investment. As for diff gaskets, I'm not totally sure because I've never really look for those. For the diff fluids on my speed run rc's, I personally use the brand Team Associated 200k CST in front, 200k CST in the center, and 7k CST in the rear. A hobby shop guy told me that with a 4x4 rc, you'll want to have most of the power generated in the center and also in the front so that if you end up gunning it it'll have less trouble with handling because having serious power going mostly to the rear will create tailspin/fishtailing. The thicker the fluid you use the more power its going to disperse which will cause more stress on all the attached drive components and act closer to a locked diff or spool. Those diffs heat up quite a bit depended on how frequent it's ran without cool down time. Some people have experienced their diff melt. Hot Racing sells an aluminum center diff (FYI) if you plan on sticking to using a center diff. If it's raw insane speed you want, I'd suggest in looking into replacing your center diff with a spool. Also keep in mind that if you plan on running off-road, I wouldn't use high gear ratios nor a center spool because it will blow your motor, esc, and put hard stress on your lipos with mad heat all around. All the stuff I'm suggesting here is for on-road only and you'll want to use a temperature checker to make sure the temps stay well below 160F. Solder starts to melt away and electronic tend to short circuit and fry. I don't really have knowledge of off-road fluid usage, but I do know if you have a 50T mod 1 spur, you'll want to run with a pinion that is 16T and lower. I have a video where I used a 50T spur with a 22T pinion on my Kraton off-road and the esc kept cutting off on me every time I came close to full throttle until it just started cutting off completely from all the heat generated. Luckily the esc had heat protection (or so I'm assuming) and nothing got damaged from the heat. I use the "Duratrax FlashPoint" and here is a link to Amazon below.

will this spur work on typhon
bigfan man Yes, but you might want to add a few washers to the outdrive part of the spur because the screws that secure the spur to the center diff case run against the motor mount. You can see the chaffed parts somewhere in the last 10 minutes of this video.👍👍🏎💨💨💨
i see 80 mph coming soon on Kraton....BASH-ON
Thank you! I think I need to shim the steering. It doesn't stay straight like my Typhon did on 29t/46t. I felt comfortable getting the Kraton to 76mph on the 30t/40t gearing, but feared it'd veer off into a power pole. I was only pulling 3/4 throttle for a very short period of time and almost lost it trying to gun it to full throttle towards the end. lol
Diff gaskets are so over priced.... 3 for almost $8.... You should get 20 to 40 for that price, their damn paper....
If mine get destroyed from wear and tear, I just don't even bother to replace it. The chassis will be a bit messy though.
U need a 52 teeth pinion an see the difference. I run these on my talion an Savage x.
Roosevelt Raines jr That'd be a pretty huge pinion.
A 52t pinion?🤯
Thanks wanted more speed without the spool
My pleasure.👍
if thats the way you ran your batteries and your running two 3s lipos, you were only running at 3s
With the Castle connector, I currently don't have a parallel wire harness. The only wire harness setups I have are in series if I'm not running a single 6s brick.
based on this video with the xlx and the battery plug its a parallel setup, it looks like positive to positive and negative to negative
Oh...I'm thinking the liquid electrical tape and other regular electrical gave that appearance, but I can assure you that ever rc I have runs either in series or single pack. :-)
You said "that's real gooood" lol...
SUPER-SET RC LIFE 👀👀👀😂😂
lol
Is it just me, or when hes screwing everything in on fast forward it ummmm sounds like a teenage boy with a bottle of handlotion?
🤣😂🤣😂🤣
You said "that's real gooood" lol...
deonte cook Lol... thanks for watching!
