**Race report -** 04.04.2009, 10:14 PM

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.

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.

RC-Monster Mike · 04.05.2009, 09:04 AM

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.

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.

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?

super dave · 04.16.2009, 12:25 AM

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?

super dave · **pinion -** 04.16.2009, 10:24 AM

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

super dave · **race report -** 04.16.2009, 01:46 PM

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.
