How To Change Pinion On ARRMA 4x4 Mega and BLX RCs - Easy Upgrade

This is a tutorial that works across the ARRMA 4x4 lineup: Typhon, Senton, Granite and Big Rock. It's a simple way to get a little more speed. Going with a smaller pinion will reduce speed and lower motor and ESC temps if you are overheating your car. I bought a 17T pinion because I think it is where I will want to be when I go brushless...though I may jump up to a 20T. If you want to stay brushed and go for 30+Mph, you will want a 27T pinion. These are all 48 pitch gears. IF you do go to 27t, don't bash with it and only use on cement.
Pinions:

The ADJ. Mesh Aluminum motor mount allows you to put whatever size you want on the older versions. It's usually $15 or less on Ebay or JennysRC. This also will allow you to switch to 32p teeth gears. Great video! Great information!

Thanks for the video. I'm a visual person and your video really helped me understand how to disassemble and reassemble the motor/gear assembly. I'm not sure if it's a design flaw but my son has been driving it on our long gravel driveway and the very fine dust and some small rocks have gotten into the motor/gear assembly and eaten away at the main plastic gear. 😟 Now that I have an excuse to order a new main gear I'll also order the t20 pinion upgrade. 🙂 Thanks again.

Yeah this is my first Arrma and I love the simple design and layout. Makes working on it quick and easy... I have the Arrma Typhoon Mega 4wd also. Im putting a 3500kv 3S brushless setup in it now. What pinion gear size did you end up running for general bashing? Just so I can get an idea on where to start.. Also have you broken or upgraded anymore parts on these for the bigger power & speed?

@kylekallies3381 3 года назад

I agree very easy to work on I used 3s LiPo just to see if the motor would hold it and it of corse didn’t so I had to replace the motor which was actually cheap $21 bucks for a new mega 550 motor

@patmarcus172 3 года назад

Is there a significant difference in run time when you gear up or down by a "few teeth". One of the reccommendations Im hearing for getting more Vorteks run time is to gear down to 15T from stock 18T

@Evan-rq2ee 2 года назад

My gear mesh is right, but when I put it on the car, it screams like the pinion is too close, also do you need grease for the pinion and spur?

@brianu33 11 месяцев назад

My PTO r bearing broke on my Typhon 3s. The one side that always breaks has half blue ring under a metal shield. Do you know what it is. I don’t think a new bearing willl lay right. I can’t even get the metal shield off not sure if it’s part of broken up bearing. I posted a video on my channel if you could take a look. I’m new to this and completely stuck. Thanks 8n advance. If you need more video or better please let me know.

@spinster4000 3 года назад

I recently got the Arrma BLX100 combo and I’ve noticed the shaft size was too big for my current pinion and so I swapped it and found one of my 17 tooth 32 DP pinions that fit perfectly. Now the only problem is the spur gear, it’s still a 48 DP spur gear and it’s a 91 tooth. So I was wondering if I could swap to a 32 dp spur gear but keep the teeth the same? Or will I have to go with less teeth, I need help on this I’m clueless lol

You shoulda got the 120amp max 10! 4s fam! OMG! it’s quick af! Can I ask though. You know why the blx comes with a 57spur and the mega a 91 spur? They are different pitches but will that make them the same final drive? Arrma put a bigger pitch on the blx’s to stop them from churning gears?

i just installed a 26T pinion and new Metal Spur gear in the slipper clutch. But, feels like I have a stall on 1st punching the throttle, but when she gets going OMG its insane. Keep in mind the 26T Pinion is literally maxing out the space allowed on the mount, and so Mesh is very difficult. Lets say I wish would went with the standard 23T

When you took out the red thing next to the motor, did you do something else before drag out the motor? Or you just took out the red thing and then the motor? I have a granite blx v3 3s and it is extremely difficult to take out the motor

@CCxRC 3 года назад

It can get dirty and hard to slide. Once the red piece is out, you lift on the tab and pull.

@crazylarryjr 3 года назад

While i understand the idea, the 3s BL line is $319.00. You said $229 for the car and $101 for the BL setup, that's 330.00. Also the better support for the long driveshaft on the 3s version. Not saying this is bad, but you save money in the long run, by getting the 3s version and turning the End point on the throttle down a little

@_N4VE_ Год назад

If my motor shaft has play and can wiggle around does that mean it’s bad? Took apart my brothers granite today cuz after a jump it started making grinding/chattering sounds. I assumed the spur stripped but it seems fine. I only notice the excessive play on the motor shaft. I’m sure the diff gears are fine since they’re metal.

@CCxRC Год назад

motor bearings might be toasted. How hot was it?

@@CCxRC it was pretty hot but I could keep my finger on it for 3-5 seconds. didn’t hit safety cut off ever. i pretty much confirmed it’s the motor tho cuz I took out the one from another arrma vorteks and it didn’t have play like the broken one lol. so my brothers gonna upgrade to 3s brushless now 👍🏽

How do you choose which type of pinion to use? I’m upgrading my granite mega to the firma 85a combo and I’m not sure which pinion to use. Thank you

@CCxRC 3 года назад

I usually stay with the same size as was on before and then see how it does. If it doesn't run too hot and you want more speed, go up 2 teeth or so. If the temp runs too hot, go down a couple. But I'd try the same ratio when you give it more power via the motor.

So lemme ask you something. The smaller the tooth the faster it is? I’m new to this. I have one of these coming in the mail next week

@quarans08 3 года назад

I believe smaller tooth (e.g 19) has more acceleration, less heat, but lower top speed, and a bigger tooth (e.g 23) has the opposite, less acceleration, more heat, higher top speed

@donuttime2507 3 года назад

I've got the 3s and just a bit of advice from me. I've threaded 3 screws trying to change the motor mount and pinion. Arrma lock there screws in so tight so just be careful you don't go to hard on the screws.

@CCxRC 3 года назад

If it’s hard...use heat to help loosen the bond of the thread lock. Put a soldering iron to the bolt. Luckily these ones came out real easy. I’ve had a few tough ones on the Kraton 8s that needed heat

@DJSpannamanUK 3 года назад

Grass and mud (off-road) is harder to drive on. Thus putting more strain on the motor. You can just about get away with more pinion teeth on road cos it’s flat and smooth.
