first run~
 
got my first runs tonight, LOVED it!!! aside from needing a gear change only other issue was chassis slap at tops of the jumps. i would assume try going heavier on shock oil? i dont have any optional springs and LHS doesnt carry any...

Are you using the plastic under body ? If so, that is always going to cause bad chassis slap. Ditch and get the AE or JCon chassis film instead.

For the standard AE v2 shocks, you shouldn't need to venture too far from 35 front / 30 rear.

Going thru my spares, I found a couple parts from my bj4 worlds and wondered if I should run the carbon steering rack over the plastic stock one? For high traction tracks esp, but also given the currenti setups, does anyone see a reason to get any other rear hubs for the 44.1 other than 0? I considered getting the 1 degree but wasn't sure how it would compare.

Kinda dumb, but on the arms there are 1 and 2 molded in but no explanation of what they mean, guessing R vs L. Book didn't really clarify. So far a fun build. Its been awhile since I have built an entire kit.


Momo

I have been running the 44 for several years. I have built at least 5 44.1's or more. What I like the most is its ready to "race" it really needs no upgrade. But I would say if you want to do something worth the money is to purchase the 12mm hex's on the rear. I like the set up I run but if I need some push on power I keep some .05 rear hubs on hand. I definitely want to try the new avid slipper. I think it would be worth the money. The 44.1 slipper wont handle anything faster than 6.5 with out replacing it often. I have tried the upgraded thick pads and they wont last either. They were worse for some reason. Now it could be the material? The old yellow pads lasted longer.

Avid B44.1 Triad Slipper Clutch Instructions

I appreciate your input. By no means was I insulting Avid, other companies do the same kind of thing, so avid isn't alone.

I have talked to several racers who use it and it seems like a phenomenal upgrade. I still haven't pulled the trigger, but I hear much more pros than cons.

As for the triad slipper, I will wait on more feedback before I make a decision. Ive never been a bandwagon type, so I'll await some reviews before I make a decision.


Un4,
Yea, I've liked that about AE cars, just put it on the track and race it. It's the "Ron Popeil" Of rc set it and forget it. I stick with AE cause it just works!

Thank you, when that warning label dawned on me I got so excited, it was like sitting in a math exam just looking at a problem and then bam the answer hits you in the face. It will be part of our branding for a long time I feel.

I'm guessing that he means if you're running the stock lexan chassis protector it's going to be loud and make your chassis slap seem worse (noise) than it really is.

original question, no that was referring to actual chassis slap and not the noisy under tray. Which if you for some reason leave out the center mounting screws makes it sound like the car is gonna break in half:lol:

that's what I thought... so the answer above was completely off-base and hence delivered in a very peremptory manner still. The internet in 2012 just kills me...:rolleyes:

hard to diagnose your issue from behind a keyboard but yes, try stiffer oil first and then pistons #2 or even #3. That of course assumes your shock has enough oil in it to start with and that the rear suspension isn't binding ;)

In your experience how many runs would you estimate before the pads need replacing ? Can they be scraped or sanded and freshened up ? I run a 6.5, and I'm starting to wonder if it's time to replace my slipper pad. Seems like it's really hard to get it set 'just right' as of late. Been quite some time since I replaced the pads to be honest :blush:

Use 800 grit on the pad and disc in figure 8 motion. I rough up the disc when I build the kit. I flip the pad when it feels weak and then pitch them after using both sides.

So, am I alone in running my slipper as loose as possible on this car? It is the only way to avoid destroying diffs all the time.

I run vented hubs and high-torque pads, then only crank it down about a half a revolution from where the pads are loose. Seems like it's better to have it scream than bark or grind...

mmh

some people have lots of diff problems, while others have rock solid ones... I would do a full rebuild if I were you... I've run mine with a normal-to-stiff slipper setup and the diffs would hold fine. a diff that's slipping uncontrollably is typically a diff that's got graphite lube on the main balls...

I by-passed the Diffs till I get ceramic bearings. I also had a couple of other questions.

Oddly, I might recommend the stock ones at first, depending on your history with similar cars. Diffs are the weak spot and ceramic balls will destroy them even faster if you do something wrong.


-Skip the stock Cups and go with RPM?
It was my first "upgrade" and definitely helps avoid those constant popped links. However, I found that they get sloppy faster than the stock ones, so keep that in mind and plan to replace all of them periodically (probably along with ball studs, since they also get sloppy).


-I see that the SC104x4 has a vented slipper, will this one work on the 44.1?
The SC104X4 slipper will not fit. The part you're looking for is ASC7495, which is a vented V2 slipper hub. Spur gears, slipper hubs, and slipper pads are the same as those used on the 2wd AE cars.


-And am i crazy or did I see someone offering a drilled Slipper PADs?
No clue, either way. I'm not a doctor.

Just run regular (ASC9603, included with kit) or high-torque (ASC91170) slipper pads. You could also try garolite pads, but they're pricey.

I have rebuilt them a number of times. Avoiding "grinding" (stripped gears) is mostly in the shimming of the diff, where you aim for a tight mesh (with light drag), no left-right slop, and give them a tiny bit of lube. I use fresh cases every time, because they take a beating and get sloppy (I also noticed a decrease in diff damage with this).

The diffs are not slipping uncontrollably, they bark and rip up the rings if the slipper it too tight, or if the gears are not meshed perfectly they will strip. Which goes first depends on which is the path of least resistance, but either case requires a diff rebuild.

With the looser slipper I've run diffs until they became gritty from age, rather than replacing them after damage.

Here's my method for diff building....... Your eyes are going to hurt on this post....LOL

All stock and trust me you will have a better diff if you use the stock rings and your diff will seat deeper and have more ball surface in the groove of the ring and with more wear life and more spring tension than thinner sanded rings. The more ball you can get in the groove the more agressive grip and longer wear you will achieve.
After I put the diff together I don't tighten it. I set the tension just enough to get the opposite out drive to turn the other way. Then I put a slow speed drill on it and run it both forward and reverse for at least a minute. Then I use this method in 5 increments.

Then the diff is almost set. I set the front diff to the stock setting and the rear just a slight touch less. Even with a 5.5 I can get several weeks out of a diff.

I put all the shims on the gear side of the out drive and put 5 spots of diff grease on the gear before sealing the case.


Before building the slipper I scuff the pads on the side I am going to use and the slipper hubs in a figure 8 motion. After they glaze from running I scuff the new side flip the pad and clean and scuff the hub. When both sides of the pad are used I pitch them and buy a new set, there to thin at this point IMO. The slipper will remain more consistent and glazing will take longer before occurring. I use Denatured alcohol to clean the slipper assembly before final assembly.

Setting the slipper is an art. I will never master it. But I do it the same all the time. I run the kit with the stock setting for a battery to insure all is broke in. I run it kinda hard but not race hard. The kit setting is loose. So I then begin to tighten it, but only about a 1/4 turn at a time till I get so I feel like the power is getting to the ground and I want it so that the kit will just break loose. I run dry wet dusty and never know how the track is going to be so knowing settings for all conditions helps and takes lots of practice nights to dial in. I sometimes have to tighten the set screw to get the diff just tight enough. I like my front diff tighter then the rear.
If you set it on medium bite your there. Its set and you can forget it pretty much. When the diff is right you just know it and can feel it. If on high bite 1/8th tighter and it will feel good if its loose 1/8th looser and it should be good. It all can vary though.

If you take the time to build the diff right it should hold up even in a real tight slipper setting. At our track the pros set them so tight they wont slip on a rubber mat...LOL

On power throttle control saves the diff. Off power I see more blown diffs due to just plain to much breaks. Dial the breaks down and try not to hit them to hard when in the air.

Go Fast and try not CRASH!!!!

UN4RACING 08-29-2012 06:49 PM

AE ball cups?????

There the best IMO. They will all wear out its just how it is. But the AE cups are easy to snap on and hard to pop off. I can not count how many times watching a race I have tried to snap on other off brand types and needed pliers to get them on for racers and the hole time thinking how did it even pop off. I doubt any of us will win a race after any brand would pop off but you can get back out quicker if a marshal or onlooker can pop it back on with a finger and not snap any plastic.

Stick with the stock AE ball cups there a great design.

EricJ 08-29-2012 07:11 PM

I don't sand them. In fact, I don't sand them for any of my cars, since all it can do is make the surface more uneven than it came. I do clean them, but that's it.

I'll try this next time. It sounds like it would be more reliable than the usual hold-one-side procedure, though I have seen many months on a diff done this way, so it can't be the worst way to do it. It also sounds like some kind of jig with a motor for running it a while on each side might also be beneficial.


I put all the shims on the gear side of the out drive and put 5 spots of diff grease on the gear before sealing the case.
If I put all the shims on that side it'd eat the gears alive. One of my diffs takes 3 shims on the gear side and 2 opposite, while the other takes 5 and 3. Mind you, I've played with it a lot and my friend that owned one long before me also went through a lot of this, so he gave me some pointers.

This is essentially my method, though I usually tighten it slower than that. The end result is usually not much more than the stock setting, usually less than a full revolution.

That couldn't be easy on the diffs... When I ran mine tight the diffs were gone in no time.

Very good point. I also noticed that braking too hard will damage them, so I have mine dialed down for just this reason... Too much braking in the air and you're going to lawn dart it, anyhow.

It will feel tight for a couple of packs but it will loosen up. It works. Been doing it for years.

You have it absolutely right. Anything needs time to break it once shimmed. Trust me, you'll want those shims in there. You want no side to side play when your diff is seated in the bottom half of the diff housing. It will break in, trust me...you don't want that thing being too loose.

sorta yes, first run out i heard alot of chassis slap, turned out i forgot to tighten out one of the screws on the underbody i hope, ill find out tonight... but with our new layout on a big outdoor 1/8 track, on my 2wd i was rdy to go up in shock oil also...

hesh 08-31-2012 05:43 AM

first race night with mine, took 3rd racing with open short course $$$ was funny watching this little thing dart in, around, through, and even under SC trucks.... had fastest lap even... think i just need to dial in the shocks, and mess with some ballast weights :)

Lonestar 08-31-2012 06:59 AM

the thing is there is no "standard" setup for diffs, neither for building the shim nor for shimming them. Depending on which batch of diff cases, you must shim the diffs completely differently for instance... now think about how hard the diff spring is - so hard that like 1/8th of a turn can make a heck of a difference on how tight your diff is. Then think about how the tolerance on all the parts add up... I don't recall the recommended number of "turns" of the diff bolt in the instructions (say it's flush with the t-nut, for instance) but it isn't hard to imagine that one diff built flush will slip while another diff built flush will be too tight...

I like the idea of breaking them in with a drill when they aren't very tight though :)

Paul

UN4RACING 08-31-2012 08:47 AM

No argument here. I have done my diff the same way for years. Its my standard diff build and procedure. And has been my best result after many attempts to get the best result for mod racing. For stock the only difference in procedure is I would shim the rear gear freer with less grease on the gear and I would run a one way in front.

I think to a degree the slow break in makes the diff last longer. I do not sand my diff rings just clean them off before a build. You end up with a good thick diff ring with more spring and diff ring tolerance making the diff and thrust bearings more evenly torqued. Not sure if that's the result but they did make the thrust washers thicker and the bearing smaller? So who really knows on that. But I would bet tolerance was a part in design and testing before the end product.

The slow break in will end up with less break in heat and ultimately allowing the diff and ring to seat with less stress on the ring before hitting the track. And you get closer to a full torque setting before hitting the dirt. Less chance for the diff to prematurely get gritty. I have done this and not even have to set my diff after running it in with the slipper set perfect. 4 to 6 inches of slip work well on our track. 4 inches is pretty tight.

The diff and slipper are a team and they have to work together. So screw up one setting it can all go bad pretty quick none the less. GRRRR!

My kit will be in tomorrow. So looking forward to get back into some 1/10th 4x4. Been running 1/8th all summer.

Breeze 09-01-2012 05:19 AM

Has anyone installed the triad slipper in there B44 yet? I have the instructions but when I put it together I had a lot of back and forth play, I used the shims. Also does the 1 side or the 2 side of the spur face the front of the buggy?

There is a little bit of play but not much once it's all in, the 1 pad side goes toward the rear.

UN4RACING 09-01-2012 07:00 AM

Keep us informed. I am a bit skeptical about the beveled washer in the design. After I use up my present stock pads I want to try one out.

The RCShox GAROdiscs do not wear and do not glaze. They also hold your setting, the car will perform the same from start to finish. You also dont have to sand them.
They feel more like torque control than anything else. you can run them extremely loose and still make every jump.

I ran them in my sc10 4x4 for several months, then in my Durango and now I put them in my b44.1 I'm talking about the same set of pads! They don't show any wear and work as well now as when new. If my SC 10 couldn't cook them I think they are pretty tough.

Standard AE pads are $6-$7. So for two and a half times the price you get something that may never need replacing for as long as you have the buggy? That plus the constancy is worth it to me. They don't fade even on a high bite track where they are working hard. The only reason I have to adjust them is if the track conditions change and I want more or less slip. I almost bought the avid slipper but didn't see any advantage over the stock setup with Garodisks.

suprdave 09-01-2012 10:07 PM

Hey guys looking for a little insight. I currently have the original B44. Its getting a little long in the tooth so I'm thinking about a new wheeler. Looking at a couple different brands but mainly wanting to know how much of a difference a guy will see going from the old 44 to the new .1, what does the newer car do better or worse than the old one ect....
