Race report
 

I figured I would start a thread on racers experiences with the Slipperential. I got mine on Thursday. It went together without a problem. I found I needed 2 gaskets on the diff side. It says to do this in the instructions if the gears are tight. So in all it went together without a problem. So I dropped it in my Losi 8ight-E buggy. I did need to trim some plastic from the plate under the diff. I am running the MMM 2200kv on a 4 cell lipo.

I raced today and was pleased with performance. It takes a different driving style. I found you have to drive it more like a nitro buggy now. You need to roll up to jumps instead of relying on the instant acceleration of the direct drive setup. But I was able to turn smoother laps. And to be honest I felt more at ease knowing some of the shock was being taken away from the motor.

I went with 7k diff fluid in my center diff. I am wondering what some others are running? I ended up with a .060 gap between the pressure plate and aduster ring. What have others found to be a good setting?

I am happy with my purchase. It's a very nice part and I feel worth the money.:yes:

Glad you got it built and installed in short order, and it sounds like a good race day. It sounds like you have a decent amount of slip dialed in, which should really make the slippery tracks much more drivable, but I encourage you to tweak the slipper settings as you continue to "get to know it" - you may find a tighter setting works well on a high traction surface(the slipper will still slip when the hard impacts occur), and use a fairly loose setting on dry, slick surfaces or "blown out" track surfaces. That is the beauty of it - it adds another element of tuning along with the protection. :)

I was kind of limited on practice time. I wanted to try a tighter setting. But was afraid to change what was working and screw myself up. So you would consider a .060 gap a loose setting? That's why I am a little curious as to what others are running. I hope to get a little time to tinker with it next week.

A couple other drivers ran my buggy. They wanted to see the difference the slipper made. After a couple laps they where impressed. I think you will have a couple more orders shortly.

.060 inches is equal to about 1.5mm of gap.

I believe that somewhere it says most settings should fall between 1mm and 1.25mm.

The 1.25mm is meant to be a base setting - to be tweaked from there. We found that this is a reasonable starting point - may be a little stiff in a buggy and a little loose in a truggy (dependent on other factors as well), but need a baseline for people to start with.
I really can't say how well this will work in your particular vehicle at your track and with your driving style. Factors such as traction, vehicle weight, track conditions, etc. all play a role in how well this setting actually works. I was basing my observation on your description of the driving characteristics - this is ultimately what you are trying to tune, so the "gap setting" will fall where it may. This .06" setting is helpful information for others looking for a similar feel(or for you to remember when trying to duplicate the setting), but the track conditions, etc. will ultimately determine the best setting. Your description sounded as if it had a fair amount of slip - if you like it, you can certainly leave it here, but you can also tighten it and loosen it as the driving conditions dictate.
I guess my point is that the unit has a high degree of tunability (is that a word?), so I want to encourage people to tweak, tune and dial it in like they would any other tuning aspect of the vehicle.

Well I was running on a tight indoor hard packed clay tray. Running Panther clay switch tires. It is pretty high bite in the groove. But if you get out of the groove it is slick. After thinking about it I wrote down .055 when I set up the slipper. So I had it slightly tighter than I first reported. I could have stood to have it a little tighter. But the slipper did help to keep the buggy between the pipes on a tight track.:rofl: I look forward to working with it a little more.

i built mine yesterday morning during practice used 10k oil and raced it the rest of the day in my rcm rc8t truggy,track was big FAST and had a nice blue groove, i was running m2 holeshot lprs for the day, i was i did happen to miss the part about the 1.25mm setting at first go and though out the day , i was geard for 44mph and tested settings every where from 1mm to 2.5mm at the end of the day i really liked a 1.4mm setting i know this is supposed to be slightly loose but i roughed the plate up real good where is contacts the pads when i built it, the truck could still EASLIY wheelie down the straight away and really ran great, i also broke my personal fastest lap and my personal fastest qualifer yesterday, im very happy with it!

btw has anyone else noticed how quiet it runs even though its metal to metal? i was asked if i was running a plastic spur gear on my truck more than once yesterday...

I did notice my buggy wasn't as noisy. I thought it might be my imagination. But now that you mention it I guess I am not alone.

test report
 

wow this slip diff is great what a big inprovement is the car. yah it is very quiet now, but i read in the other thread that it made someone change their driving style a bit to suit the diff action. i didn t find this ! my car was good mbx5t, into corners better mid and out so good just better all round i am very happy with this diff. ( i ran 2050 nue v3 6s 12-46 and city blocks )

That's nice to hear, r u using motor brakes or mech?

yes motot brake, i find it easy to adjust as i have on a button on the radio

wats the smallest pinion u can run with ur 46 slipper diff?u r using rc monster motor mount?

pinion
 

i am not sure on all the different cars, on my mugen 6 the smallest is 12-46 and i am sure you can fit a 11 on there, on my mbx5t 12-46 this is very close to being the same as the buggy and my rc8t the same, the slipp diff gears is the same as any other 46 spur so no big deal there.

good idea, i will try a normal 46spur first & see the speed

race report
 

it looks like you are listing crt with 2000 motor,, so if this rite you should be ok with 12-46 and then just depends on which batteries you run, this is my second season with a combo close to that and i am very happy with it. the slipp diff did make a big inprovement.

thx wat I worry is I can't get my pinion lower than 11t becoz I down size my spur.

I will be using 4s on 11t n 6s on 9t on 46/50 spur

firts race with my mugen this weekend at the track i won a club race last year with almost the same car except nitro.

it was part of 1:10 electric national chaps so we used same system
4x5min qualifier - who knows how many count
3x5min main - 2count

since it was my first ever race with electric i was taking it kinda slowly. especially MGM does not brake strong enough to my liking (its sold now and RX8 frome Mike is on the way).
track was hard packed and very abrasive.
slipperential was at default setting with 17k oil (7k front, 2k rear)
my mugen has MBX6 shocks and pillow balls. BCE chassis, 2mm offset buggy hubs to make it more narrow compared to standard MBX5T

qualified 2nd with only .7s slower run

1st final - 2nd. just did not want push the car too much
2nd final - 2nd messed up start a bit
3rd final - 3rd. got hit from rear (was 1st) after start and thanks to slow marshal eneded up at last 10th place. Well with nothing to loose i started to push the car like I should have from the beginning. Was second with like 2 mins to go but I just wanted to be 1st so pushed even more made small mistake and finished 3rd. the track as just too easy.

5 mins is just not enough.

During the last run I finally had same lap times as with nitro last year and I can get them better with car that will brake better.

Next race is in a month, cant wait for tekin as i really need something that will brake :)

Slipperential worked flawlessly. It makes the car so easy to control.

ok it's was my turn now, i raced with the 50teeth slip diff.

Crt x1 with x2 gearing
4s-6s 5000 zippy
Motor medusa 1600kv
Pinion 16-12t
Esc hobbywing 150
Rcm kit
50 slip diff

I had 2 heats 7min each, the car no longer wheelie n was more stable corner in n out fast without spin out.

I was driving stable n smooth, I did not push d car very hard as the slip diff was sitted with a spacer on each side.

The fastest guy was clocking 37sec me 40sec.

1st heat I finish 5th out of 11drivers second heat I was 1st I did not overturn at all.

Then d finals I was in Amain postion 5th. It was a 25mins main, in 15mins I was second already I was supposed to come back in 20mins to change batt but I changed my mind wanted to push d batt to it max.

I was using 6s 5000 esc set at 3.2v cut off, but at d 20mins my motor desoulder n I hv to retire. My motor was at 60degrees esc 50 n batt 50.

I m happy that d diff made the car so easy to drive. It's a good invention by mike.

Nxt race I will try again with 2000kv medusa n with 8000 batt. N hope to finish first.
