thanks Beaver! since this is my first mini rc car, i dident know what to expect, but both wheels are rolling perfectly now and that works for me :)

I recently upgraded my AWD MA010 to a full drift spec partially based on your videos. Thanks for that! But I wanted to chip in on this left side diff issue. My kyosho front one way also has the same issue on the same side. When I throttle and brake so the front wheels spin freely, the left wheel of the car always stops a bit sooner. not by much, i'll also keep and eye on things and keep you informed. Thanks again!

Darkphizer nice! So the conversion worked, that’s great to know!! I think part of the issue with the front one way is they require a bit to break in & become fully lose. Also, don’t lube your bearings. I thought lubing them up was a good idea, but everyone on the forums said to run the bearings dry since the lube will create more resistance (at this scale) & attract dirt that will slow the bearings even further. I’m glad my video have helped! I love to hear when people find my videos informative & useful. Have a great day! Let me know if anything changes with your set up

Darkphizer wait, did you mean the 020 front end conversion worked? Or that you upgraded the differentials?

Great video! Wish there were more videos like this out there. Subscribing for sure. One thing, those are universal joints or CV (Continuous Velocity) joints and not swing arms. The parts that you slid the pins out of are more like swing arms.

Hey @bmr 3, Ive been watching your videos for a little while. You do great work!! What one way do you use on your MA 020? KYOMDW017 says its for MA 010 and MA 015. Its the only one way i can find so far.

Hey brother sorry for the delayed response & thank you for the support! Yes it will work, the Mini-a AWD have universally compatible differentials so its will for sure work.

Great Video! I installed a front one-way in my car and I couldn't have done it without you. I just wanted to ask for some advice. I'm pretty sure there is something wrong with my front oneway. I did the same thing you did at 2:32 and all 4 wheels just locked up. It might be dog hair clogging something in the car or there is something wrong with the bearings. Also when I reverse all 4 wheels spin even though in the comment section on one of your other videos you said that only the rear wheels will spin when you reverse. Thanks for the help man :)
@BMR3
@BMR3 4 года назад
Sorry this got marked as spam so i dident see it until just now. Have you lube the front one way? It sounds like it has a major issue if the front wheels are spinning in reverse.... It may even be a lemon or have a damaged internal bearing
@extremerc2972
@extremerc2972 4 года назад
@@BMR3 I haven't lubed the front oneway but it seems to be doing what it's supposed to. If I brake while going relatively fast the back spins around and the car does a 180 degree turn. About the be bearings I used the ones from the old differential because bearings didn't come with the front one-way. Thanks for replying 👍

Sorry to comment on such an Old video. Im running an ma020 essentially stock. I’ve noticed that when I pull the throttle just enough to get the wheels rolling, one of my front wheels does not roll until Im at 50%+ on the throttle. It’s also a bit quicker to stop rolling than the other front wheel when I let go of the throttle. Any idea what the issue may be?

@kyotei2
@kyotei2 Год назад
What kind of oil do you use for your bearings?
@BMR3
@BMR3 Год назад
Extremely light weight silicon oil, it’s the stuff used for Airsoft blow back units. In my experience it’s the thinnest/fastest & still provides long lasting protection. I recently tried to switch to the Yeah Racing bearing oil & it’s way thicker & slower.

Quest8i it normal when I back up an turn the wheels one way one wheel locks up with the one way diff? The other way they both move.
@BMR3
@BMR3 2 года назад
yes and no. This does happen from time to time depending on the QC from the factory. If you have a controller that has EPA adjustments you can limit the end point on the side that's binding to prevent it from locking up.

Hi, what was the first issue that make you start diagnosing the whole front system? I just installed my front one way diiferential and i want to make sure i don’t have the problem or don’t realize i’m having the problem. Thanks
@BMR3
@BMR3 4 года назад
I noticed that one of my wheels had some resistance & was spinning much slower then the other side. As long as both of your front wheels roll the same, then you are fine. Basically I just needed to clean the bearings, relube the diff & everything was working fine again

I’m new to mini z but I have an issue where I turned off the mini z and turned the front wheels left and right because I was trying to see how well it can turn each side now when I drive around it doesn’t auto center anymore it stays stuck turned all the way to the left or to the right does anyone know what’s wrong?
@BMR3
@BMR3 4 месяца назад
Sounds like the servo is sticking. Do you have a controller with EPA? May be able to turn the settings down so the wheels don’t lock. If not you may need to pull it apart and check for obstructions & clean it out. Good luck!

Hi, what is the reasons to upgrade the front differential and rear axel?
@BMR3
@BMR3 Год назад
Better control. The front one way acts like a e-brake & a solid rear axle forces both tires to spins at the same rate so you have quicker transitions on a tight track.

Hi bro, I have done the upgrade for "Front one way differential" but when I roll either one of the front wheel forward, the other front wheel did not move. The front wheels can only roll independently. Next, when I roll either one of the front wheel "backwards", all 4 wheels follow moving backwards together. Did I done it correctly? Thanks

It barely rolls. When I had my ma20 the front wheels spun for quite awhile after...
@BMR3
@BMR3 4 года назад
In this video my front one way was still brand new & not broken in, so it wasn't spinning 100% freely. The point of the video was to get both wheels spinning at the same rate, not for as long as possible. Were you running stock bearings and was your car a 020s, or a standard 020 chassis? I think the 020s have lower quality components, i will be looking into bearing upgrades down the road.

BMR 3 do your front wheels spin free now, after 5 month? (I also have a new one way diss and it behaves similar to your video)
@BMR3
@BMR3 4 года назад
Yes but I switched to ceramic bearings so it’s not really fair. But my one-way also took a while to break in, just give it some time and your wheels will become more free.
@lh4039
@lh4039 4 года назад
Do you have to add lube or oil to the drivecups for the front one-way to work because when I accelerate and let go all of the wheels lock up. Here is what I mean. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-LyPQCK7Xdlo.html
@BMR3
@BMR3 4 года назад
There is no volume in that video so it’s hard to tell, but are you just letting off the gas & letting tires coast, or are you hitting the break as soon as you get off the throttle? You have to immediately hit the breaks to get the rear wheels to lock up & the front wheels will only spin for a moment longer. Is the one way brand new? They require a break in period & it’s a good idea to put some light oil inside the one way to make sure the internal bearing is nice & free.
@lh4039
@lh4039 4 года назад
@@BMR3 Thanks for answering😀In the video I just let go of the throttle but when I brake straight away instead it does the same. I'll put some oil in the little hole where the drivecups go into. What's a break in?
@BMR3
@BMR3 4 года назад
Beak in is just the time it takes for the parts to wear in & work smoothly. Basically just drive the car & the front one way will get better in time.
