Is anyone going to make metal replacement gear diff for the Miniz AWD (MA 010/015)

If not, what about just the spider gears?

Kyosho?, Atomic?, PN?, 3Racing?, X-Power?...Anyone?:D

I have a pair of these hard diff gears, I did not know they had metal spider gears. So I just took one apart to have a look inside and you are right! The bevel gears on either side are still plastic, but I haven't had a problem with those. This assembly also gives you metal outdrives too, it's a nice part for the price and I like to use them in my AWD too.

Yep!

I found the gear diffs worked extremely well in my awd cars, especially with the correct amount of grease added in. I only switched to ball diffs so there was always a part of the drive train that had a little give during impacts.

Also would like to know if these hard gear diff metal gears (Or the entire buggy gear diff with the 3 metal internal gears) will work with the MA010 /MA015 AWD???... :)

Yes, I use the buggy hard gear diff in my MA-010. Direct drop-in, no shims needed at all. I run mine dry but I will try them greased as TheSteve suggested.

The rear should be quite light, the front is best with a little more - no where near packed or anything though, you don't want it oozing out.

1)Has anyone tried running one gear diff and one ball diff?
I tried a stock gear diff in the front and a ball diff in the rear it seemed to give me more turn in and more on exit, but stopped using it has the stock gear diff would break.

2)Has anyone tried running the gear diff in the rear and ball diff in the front?

3)Also what do you guys think might be best set up? (both ball diff or both gear diff or variation of gear diff and ball diff)

4)Any ideas on expectation on handling with the different set up?

Thanks in advance for your input.

My AWD was handling extremely well with the gear diffs front and back, the grease can make quite a difference. I tuned mine like I would tune a 10th scale touring car - tighter/stiffer front(more grease) and a softer rear(less grease). I did get the odd click from the spider gears though. I figure it was only a matter of time till the diffs died but before they met there natural fate my car was stepped on while I was full throttle, that finished them off in one quick shot.
The hardened buggy gear diffs and buggy ball diffs were both released by Kyosho out about this time so I bought a pair of the buggy ball diffs. I also installed Atomic thrust bearings into them both. It took quite a while to get the ball diffs tuned to work as well as the gear diffs. I found the gear diffs much easier to get working well. Once I found the right settings for both ball diffs though they are every bit as good and I haven't adjusted them for many hours of driving. They also take the impacts very well with no problems or damage so far.
I will keep using and would recommend the ball diffs just because they can slip a little during extreme impact.(such as when the guy in front of you takes a turn too tight, bounces off the RCP border and right into you while you're going full throttle, we all know that crunch sound...)

My experience is good on front/rear gear diff BUT it seems that rear undergo more stress. Therefore i switch to run ball diff on the rearend. :)

Thanks for the response thesteve and D1nzfe. D1nzfe how did you like the gear diff up front and ball diff in rear?

I agree the rear diff get alot of stress, specially if the front and rear tires/wheel combo has drastically mismached roll out.

Anyone know the difference between these two Buggy Gear Diffs? They cost about the same, pics on kenon look the same, but 2 different part#'s :

MB020 - Kyosho Mini-Z Buggy MB-010 Differential Gear Assy

MBW002 - Kyosho Mini-Z MB010 Hard Differential Gear Assembly

I know that the MBW002 gear diff is supposed to have metal spier gears (What I'm lookin for). Is the MB020 Buggy Gear Diff all plastic parts like the AWD Gear Diff? Or what is the difference? Any help is appreciated, Thanks!

You have it correct, the standard buggy gear diff is the same as the AWD. The newer one with "hard" gears has some metal internals.
