Our First Upgrade - Tamiya BBX Slipper Clutch Install

With Tamiya's BBX coming one of the 'cars to have' this year, we thought we'd do a quick video on the install of one of the more important upgrade parts - the slipper clutch.
This kit comes with everything you need outfit the stock transmission with a slipper clutch, a system you'll want if you're dropping in a hot motor!
In this video we walk you through the install, adding a few tips where needed.

Enjoy the video!

I like how access to the gearbox is still relatively simple

[@Competitionx]

Agreed.

[@cfusername]

I still was hoping for a secret trick to get to it even faster. But it seems there is no way around taking off the rear part of the cage. ;-)

[@glacialphoenix5921]

I will likely be ordering the slipper after my car arrives. This install video should make it much easier for me.

[@Competitionx]

Definitely a must have upgrade for sure. Glad the video helped you out.

[@rcdriver]

Nice! Installing the slipper on mine tomorrow.

[@Competitionx]

Ya, pretty easy. Makes a big difference with more motor! Time to put a 10.5T in yours :)

[@user-vm6gk8xy4e]

Enjoyed the video. Definitely will pick up the slipper kit for my BBX. Seems to me that should have been part of the kit. If I'm not mistaken a slipper is included with the Super Astute. To piggy back off the last comment regarding the Makita Gun...Did you pick up a driver bit set from Makita as well?? Thanks again.

[@Competitionx]

Well, the BBX works well without the slipper if you're using a low-power motor. If you're going to drop in a bit more power, you'll definitely want the slipper to both help protect the drivetrain and monitor the power delivery. And yes, we picked up a driver bit set from MIP! :)

[@alexsoul247]

That top bushing on the spring looks so wrong to me in the instructions. I have installed it same as the bottom (reverse from the instructions) . It holds spring nicely, fits right in into the gearbox opening and does not touch the bearing whilst pressing against shaft nicely. It makes more sense to me that way. Runs ok and looks much cleaner. Also, you don't need to unsolder engine - you can remove it and leave it handing on wires. Less work Great video, thanks for your help

[@Competitionx]

Ya, the placement of those parts is a bit wonky - we thought so as well but kept it as it per the instructions, you know, just in case it is SUPPOSED to go that way :) You are correct, we didn't need to unsolder the motor but for the sake of the video, it made it easier. Glad it helped! :)

[@RCBirds]

Great upgrade. Curious abot your test and experienc

[@Competitionx]

Have run it twice now - once at the beach, once at a track. Both times the slipper made a huge difference in the performance, especially with a hot motor (was running a 13.5T). Definitely a first upgrade to look at.

[@gael582]

Nice model ! What is the reference of the rear paddle tires you used on the thumbnail ?

[@Competitionx]

If you're asking about the brand of the tires, you can see that info in the description of this video here: kzbin.info/www/bejne/qH6kpJiijLFnlbs

[@user-vm6gk8xy4e]

Hey There...Great video, Thanks...Also, can you tell me about your Makita Screw Gun

[@Competitionx]

Makita Cordless Drill - the best tool we'll ever have in our toolbox: amzn.to/3QuHfDs

[@AC-bl1rl]

I went to run mine for the first time today, and it wouldn't move, it was spinning. So I cranked it down a bit, and it still slipped. Went to try some more, noticing that it was just about bottomed out, and SNAP! The shaft broke. What the heck?

[@Competitionx]

What were you tightening down on - the diff or did you have a slipper installed. If you were tightening down on the slipper, it sounds like your diff might have been loose. If it was the diff you were tightening, sounds like it was built incorrectly.

[@AC-bl1rl]

I was tightening the slipper clutch.@@Competitionx

[@leegengxiang2173]

Just to confirm, the slipper clutch assembly pack comes with the exact same spur gear as stock, correct? I'd like to buy a spare spur gear or maybe a spare set of pads but not the whole assembly if possible.

[@Competitionx]

Yes, they are both the 86T spur gear.

[@TwinsportMotorcycles]

I'm curious what you used for the paddle tires? Sand Scorcher? Thanx

[@Competitionx]

Used RC4WD Sand Thrasher tires in the front and rear (fronts are ribbed, rears are paddles).

[@JarrettDorough]

"If you have the BBX" lol, yea right

[@Competitionx]

More for future owners ;)

[@bradkalman2353]

I haven't seen many people do builds or say they got them haven't they been out since last month?

[@Competitionx]

Arrives on July 20th, so just a couple more weeks.

[@jonthomas8487]

I’m wondering if going with a TA06 gear differential is a better option than a slipper. That way you get rid of the ball differential

[@Competitionx]

We actually loved the way the ball diff made the car feel (not necessarily in the sand though), but thought the slipper might help with the increased power we want to put in it. Plus, we didn't want to have to remove the gear diff constantly to adjust the fluid for different surfaces. Not sure how much that would of happened but, well, sometimes we're lazy like that LOL

[@jonthomas8487]

@@Competitionx what I’m seeing is that so far in other reviews the ball diffs are having to be removed and tightened quite a bit just after a few runs. I guess I’ll build one and see.

[@Competitionx]

Hmmm, ya, we've beat on ours pretty good and not had that issue. Yet. LOL Maybe the slipper is helping with that?

[@ZekeSkylar]

Sorry if asked before. What brand mini drill is that? Thanks

[@Competitionx]

Makita. Best drill out there! :)

[@markbruton-young9228]

Slipper nut is very close to the motor tabs, better be careful not to short out the motor phases

[@Competitionx]

Ya, thought the same thing but since the top shaft and the motor shouldn't move, it should be ok. If either DOES move, we've got bigger problems than a short on the motor LOL

[@preyingmathis2517]

Do they have a gear diff for it?

[@Competitionx]

They do, part number 54471. You can find it here: alnk.to/gKPTWs7

[@ryverchoy1370]

I’m confused. Is this upgrade more of a performance enhancement or a preventative factor? Hate having to go through all that work, esp soldering

[@Competitionx]

If you're going to keep the motor tame (ie, something like a 17.5T), it's not really needed. However, if you're going to drop some big motor in it (say, a 13.5T or hotter), then you'll want to have it for 2 reasons: help protect the drivetrain and help manage power to the ground. Hot motors WITHOUT the slipper are just going to create a ton of wheelspin unless, of course, you're really good at managing your throttle finger.

[@alexsoul247]

A tone of wheel speed is exactly what makes it so much fun. I have installed it on 13.5T anyway and tightened a bit harder. It is still a good upgrade, not as much on the performance side, but rather on longevity and care for your gearbox

[@CharlesFlahertyB]

I'm confused, it's 2wd and has a differential, what's the point of this?

[@Competitionx]

It helps provide traction to the rear of the car under acceleration. Almost all 2WD cars and trucks (both onroad and offroad), have a differential, the only exception being drift cars or crawlers.

[@cfusername]

What you think about, is probably a center differential between rear and front axles. And you're right, it makes no sense for a 2WD. But the video mentions the differential between the rear driving wheels which almost all RC cars have. Usually, if someone is talking about a diff, (s)he means the on between the wheels, because it's much more common.

なんで、本家の日本タミヤのBBXが8月発売なんや！遅すぎん？？😂

[@Competitionx]

The release date was July 20th worldwide, as far as I know.
