Sick of going through diff's on my ERBE !!!
 

Hi All,

I'm going through diff's on my erbe like tic tac's and I'm sick of it! My slipper is very loose, i've upgraded to avid bearings, aluminum diff case and cup...still, they're toast after the 3'rd or 4'th run. I think what's causing the strain is me using the throttle to control the nose while in the air. i'm not landing it throttle on etc...honestly, i think i'm rather easy on it, too easy. Which is why i'm giving up on this rig. I've spend a ton of time and a ton of money on upgrades and i'm not happy with the results. yes i am running 6s and do not want to go back to 4s...that's not why i bought it.

I have two questions.

1) Aside from ls lst diff's (heard mixed results) is there anything i can try as a last resort to beef up the diff's on my erbe.
2) What's a alternative Truggy (not interested in savage sorry) which will be much more durrable and allow me to use the MMM and motor combo along with 6s that I can bash around with.

I realize parts will break given the power and abuse we throw at them. but honestly, the erbe on 6s is a joke. i have been warned by others and now i'm swallowing that pill. I would just like to take it out once in a while and play around with it, rather than driving to a pit and have something break in 3-5 minutes or mild bashing.

Suggestions or advice on the most durable Truggy are greatly appreciated :great:

Well, sounds like you need a lst2.

Pretty much any truggy will be more durable than the revo.

Lst diffs work great in the revo if you mod the bulks and the lst cases. The rcm hybrid diff cases are the only drop in option, but Mike is not currently making them. I have heard that fastlane are making a hybrid revo bulk that will accpet an 1/8 diff, but no idea on cost or timeframe.

I never cared for truggies, boring. But the hyper st I had was very well built and looked very strong. Might be a good option?

Welcome to rcm.
 

Well welcome to the RCM forum. I am sure that there are plenty of guys in here on the know who can help with your problem. First of all for the time being can you set your power ban down just a bit to save your diffs temporarily. Yes it is nice to have crazy power, but it is not always the best choice to have things set balls to the walls. Second I do not have an ERBE but share your whole electronics setup with us and lets brainstorm on the problem (ESC, Motor, Batts, what speed are you geared for, Etc...). Just from your explanation it sounds as if your diffs might not be setup perfectly (shims?). Just an observation. Are the gears in your diffs hardened steel, or stock?

Why do you say truggies are boring? my biggest concern with going to a truggy or buggy for that matter, it's limited ground clearance and bash'ability. I just desperately want some more durability...

I'm running 6s geared for around 45 mph max MMM 2200kv neu motor. the gears are the stock traxxas ones (ring and pinion) and they have been shimmed properly. i just truly think that the erbe is not designed properly to handle 6s. I try and leave my slipper clutch as the weak link or even don't mind replacing the drive shafts occasionally, but the amount that the erbe is down is not appropriate.

Quick story, long time ago when i first got into rc cars i bought a Mauruchi Hunter (i was a little boy). at first i had a grin ear to ear when i drove it...soon it disappeared whith all the problems i had with its drive train. My other two friends had the same problem with their hunter. Then i switched to Tamaya, bought a Frog then a Falcon. Better, no drive train issues but still a little too beginerish i felt. Then I bought a RC10 and that was the love of my life (rc wise :). I started racing it and it dished out everything i threw at it...and more. Parts would wear but rarely break. That's what I'm looking for, something which is designed to handle todays MMM output on 6s.

I realize that's a big difference power wise today from yesterday's nimh and cad batt's motors etc. However, I'm just looking to take it out occasionally and have some fun with it. My erbe sat on the shelf for almost a year...now I know why i put it away.

I was warned that i would spend all my time and a whack of money on the thing...and i have. I think its time to move on. I'm hoping to use my radio (dx2s) 2x3s xps 5000mah lipos and my MMM and neu motor (have new back up in box) on a new rig.

Any advice on what truggy (maybe a buggy) to look at would be appreciated.

Yeah, limited ground clearance and I am not really fond of the center diffs for bashing. You have to fill them with thick fluid to do wheelies and such.

Now if you want the best of both worlds a Losi Muggy will easily handle your 6s setup. Run 50k fluid in the center diff, and upgrade to rpm arms and new era hubs and you will be good to go. This can handle 40 series wheels and tires, and is build very tough. Good solid diffs, and lots of parts interchange with the lst.

when i had my erbe i went through those stupid pos plastic axles all the time, and when i say "all the time" i mean like i was damn lucky if i could get a set of batteries through the stupid thing before i broke one. I know you dont want a savage (not sure why not?) but i sold my erbe and bought one and i couldnt be happier. A truggy might be boring like other have said because of the center diff and ground clearence issue. I agree with Linc, get an LST XXL or LST2 and convert it to brushless, they are the next best thing to a savage as far as toughness goes
Arent those pretty hard to come by since they havent made them in like 4 years?

Well, I wanted a truggy/buggy initially but decided on the erbe becasue i wanted something that would handle close to a truggy and offer the ground clearance of a monster truck...erbe seemed to fit the bill the best. Soon i started going through the stock drive shafts like tic tac's and diff's too. I upgraded to steel traxxas cvd's which were not much better. I've since switched to summit shafts and they seem to hold up much better. the reason i don't want a savage is bc they just don't seem to handle as well and tend to flip over too much.
i just took the front diff's off and realized that the ring bearing had let go. this wasn't the upgraded avid bearing (as is the case in the rear). maybe its time to just get out of rc cars for me once again...go back to my heli (trex 550 3g) or my yz450.

I wouldnt give up just yet. Just off that ERBE and get a LST like Linc mentioned, they are a good balance of handling and durability. I agree about the savage not handling well, but they sure take abuse like a champ.

You still see them up for sale here and there. Sometime I wish I had not sold my muggy.

As far as handling goes, alot of people think the revo handles really good, then they race a lst2. Considering its size and weight Losi got the lst2 right, it handles as well if not better than the revo, especially rough terrain.

Consider losi has 2 distinct sections, their race and sport branches. The race branch is responsible for the eight lineup, the xxx 2wd electrics, and the lst series. True, the lst1 was not all that great from a durability standpoint, but losi fixed that on the lst2 and it is a great platform. Losi makes their parts very well, some of the best molded parts I have seen.

After owning alot of revo based stuff I now only have a summit, and as far as I am concerned it is the best use of the revo chassis.

And I understand about the dislike of the savage. I have had a few and still have a few, and I really would not miss them.

I completely agree. I recently did a custom chassis for my LST and the handling is awesome. I would of raced it last weekend but i keep having reliability issues, these issues are cause of stuff i made not stock losi stuff.

Also, i think the added weight may actually help it get better traction and make it feel more planted.

I also regret selling my muggy but at least it went to a good home (v8Hatch)

Just my $0.02

As for the e-revo issue. i completely agree with what has been said above, sell it. buy a LST2 and have some fun. I also own an e-revo but it is primarily for racing and i never use it otherwise, i also have an electric revo which i bash but not very hard. Technically i own 2 LST XXL's, they are great, once you get them set up the way you like it you will love 'em. Just remember to shim the diffs, if you don't they can break.\

Wow, i really hope this all made sense.

I have to disagree. The LST/LST2/XXL are fun MTs, they are tough... enough. But as for their handling, they are big fat pigs. :yes:

My last diff problem was a bearing which let go (front diff's/first time) and the rear is where all the mods have been made (avid bearings, aluminum diff cup and case) and it's seems to be holding up. Time will tell.

My question to you mistercrash is, I know at one point you moved to another MT (which one was it), did you go back to the ERBE, is so why? I've seen your lst2 diff mod, are you having success with this setup?

Sorry Mistercrash, but you're the man that just might save me from selling her...I still love it :)

FLM answered my email now, and said theire alu bulks are in testing now, and might be in production in 2weeks time or so...!

Earlyer they said they will be making them for 1/8 diffs, so this will be VERY interesting for the Revo people..

Dont know what diffs they are testing with / making them for though..
And i`m to polite to ask more questions about it.

http://www.rc-monster.com/forum/pict...&pictureid=837 Will Race Your Revo Any Day See Ya lol!! I won't even see you in my rear view lol!!

LST diffs and 2-3300mah 5s packs in parraelle, ben rockin this set up for 8-9months and recently maintinanced the diffs and they're still looking great.

The LST/XXL is THE best basher IMO but the Revo does handle 10X better

Good luck with what ever you decide to do.

well isnt that just special.....

http://www.rc-monster.com/forum/pict...&pictureid=859 My Revo Conversion Hot!!

:rules: Stop trying to hijack the thread. If you want to post pics of your truck start your own thread to do so.

Don't Hate!! LOL!!

Don't hijack the thread. :lol:

Ok Just Had To Show Off The Toys:na:

@SM456, 5 needless posts(6 including this one) having to do with nothing pertaining to the thread ?

Hi all,

My erbe has been a shelf queen for some time now. I'm waiting for some, anyone or anything to come out and rescue the erbe's weak diff. I've upgraded to aluminum cup, aluminum diff case, upgraded to AVID ceramic bearings and gone through countless clutches to keep the drive train alive. Yes, I'm running 6S...that's what its advertised to run 65+mph etc etc. But it just doesn't hold up to the use (NOT abuse) of 6S.

So now I'm thinking of going back to nitro, miss the sound, smell...dare I say, less power??! Durability is what I'm after and YES 4 or even 3S is an option, but then that's not why I purchased the ERBE. I was sold on the power and that's what I love. Not the countless diff's that get eaten like tic tacs almost each run.

Case in point, each time i head out for some bashing with my friends (they all run Savage's) and occasionally I give them the roost and show of power. What they hand me back in return is a sub erbe handling monster truck that keeps running fill after fill. That's beginning to sound like the better trade off for me, going back to nitro or on to a more durable rig.

I'm just down on this thing, starting to feel as though I made the wrong choice, spent a TON of money for upgrades and spares. Not to mention all the wrenching time. I just want to play for once without being sidelined. Help me out fellas, any diff upgrades on the horizon (not lst2), step down to 4s, go back to nitro or take my loses and buy another more durable nitro MT?

Help, I've been here too many times

savage flux, not many diff worries (just a bearing that goes occasionally) and you'll have a savage with the same power that the erbe has!
Nitro is decent too.....but electric is better ;)

I got rid of my revo love my flux best basher ever lol!

Really, should i jump ship? Here is the response I got immediately i got from traxxsucks ass .com to my vent...

http://traxxas.com/forums/showthread...ove-any-more-(

Here is what the "Marshal" had to say to my last post, he closed the thread.
Well then, there are your options:
1. go 4S or 5S and stay with the handing;
2. go nitro and stay with the handling;
3. go with the other vehicle and be unsatisfied with the handling.

Whichever path you choose, it's not a great idea to pop back onto a forum after 4½ months and immediately start what some would consider trolling and spreading lies -or at best half-truths.

you made a traxxas questioning post at the traxxas forums? surprised you didn't get BANNED.

I'll admit I'm sure the savage does not handle as well as the revo. But they are monster trucks....have you seen the real things? I would hardly call them graceful, lol.
If you want something that is tough, but can still drive competitively get a brushless truggy. If you want something to beat on with your friends in a field when they are all running savages, get a savage. You can trade for parts and borrow from each other and what not.

Yah, I know. I guess I felt like I wanted to expose others to the truth...even for a short time. Initially, I was going to buy a savage 4.6 based on what i read, but I ended up going for a erbe. I thought it should be able to handle what "I" would throw at it. Which meant, nothing comparred to what my friends were throwing at their savages. I thought they were almost abusing them. But they would take it! Granted, they were nitros and not electric. I have not seen a savage flux nor do i know if it handles the torque of 6s.

The erbe seemed to fit the bill for a "truggy" type truck with a ton of configuration ability. That's what I wanted, or was looking for, a monster truck type truggy able to bash with the savage. i don't care to rase it, that's the role of high end buggies...i just want to get out there and have some fun, a stress relief with some friends. A hobby!

Sorry guy's....I'm pissed man! I spent alot (over 2k) on my erbe to keep it on the playing field and all I seem to manage is a few (less than 3min) with them. I was warned and now I'm eating their words. Its not like my friends are being rude about it at all, I just feel that traxxas hasn't addressed the weak points as well as HPi has. Now do I just dump the erbe and jump ship to a flux and rebuild all the spare parts list etc? I know the flux will break as well, its to be expected. I just don't want to spend another xxx amount to.....you know the drill.

Ughhh, any suggestions on a "truggy" type rc car I can buy that will handle some rough stuff and keep together for some lipo charges? or is there a erbe diff upgrade (please lsd upgrade) coming or available? Help....I'm about to shelf it for good and I really don't want to.

Here's what I sent to the moderator....

Please help me (US!) then, why hasn't Traxxas come along to provide us with a more beefy diff upgrade. Clearly this is a major topic which seems to come up again and again. Why isn't Traxxas addressing this?

I feel so ashamed that Traxxas will not offer any suggestions aside from offering the following suggestions:

1. go 4S or 5S and stay with the handing;
2. go nitro and stay with the handling;
3. go with the other vehicle and be unsatisfied with the handling.

Really? Is Traxxas working on something to address or provide a more "beefy" option for those of us who signed on the 6S experience. I will be moving down to 3S and if things are going well (aka. i did not break) then I will move to 4s for a run or two. But really, I feel ripped off with this purchase. I really do, its not designed for 6s, it really isn't. My clutch is setup as per the manual, if not a tad less (it will barely wheely) and i'm running the summit shafts etc which have yielded much better results than the Traxxas CVD's. Anyhow, that's not really the problem I'm having.

Whichever path you choose, it's not a great idea to pop back onto a forum after 4½ months and immediately start what some would consider trolling and spreading lies -or at best half-truths.

I'm not a liar, if I did state a lie on my post, then please prove me wrong. I will apologize otherwise. All I'm looking for is for honest advise and help, no offense but your advise (and not posted) is rather trivial.

Is Traxxas looking into addressing its customers out with a strengthened pinion and ring as other companies have or will I need to move to the other side? I'd like to stay but I'm looking for someone from the "inside" to offer a helping hand. Is Traxxas going to help "us" and many of us out there in the near future?

Answer
 

Seems to me that you answered your own question there. Your friends have the Savage Flux and seem to have endless playtime and half decent handling. I get it you wanted to do womething different and maybe out run them, but it is just not working out that way now is it. Just do what you know you should have in the first place and move over to the Savage Flux and be done with it. Sell off your ERBE and wash your hands of all the diff problems. The only real transformation has been to convert teh LST2 diffs to fit your truck. Anything else is just going to give you headaches and keep you tooling on your toy. Screw Traxxas for being bad sports about complaints and dealing with custormer misgivings. I doubt that this is ever going to change. To run a forum where you can not speak the truth and be real is just kind of stupid if you ask me. Why even have a forum if your are not going to take criticisum and work on fixing the issues. Just like Maxamps they just don't want to hear the truth. Good luck and have some fun with whatever choice you make.

My suggestion: get a truggy and be done with it. I gave up on my ERBE and it is now my kids toy. I got me an MBX6T and converted it to a BL setup. Even though I've tried to destroy something I haven't. Only thing that I've managed to brake was a plastic spur but that was due to my own error for using a motor screw that was too short.

Advice taken, I was able to get a 1yr old 8ight t 2.0 with the electric conversion for $250. Its been used for 1yr and in immaculate shape, no slop, very little wear etc etc. Now, I'm going to be running my MMM along with the neu 2200kv motor (have spare).

Questions:

- Is there a "must do" mod for this truggy to increase durability?
- What is the best bang for buck servo I should buy?
- Will the buggy body fit on the 2.0 t frame?
- Can I use my 3.2 rulux with 1/2 " off set along with mounted badlands mounted on them? Or should I stick to the truggy tire/wheel combo?

Congrats on your new toy! :yipi:

- Is there a "must do" mod for this truggy to increase durability? Not familiar with the Losi but my guess would be shim the diffs! That's the one thing I know that's recommended for the 6T. Also get the DE Racing skids! http://www.deracing.net/store/index....ory&path=92_96
- What is the best bang for buck servo I should buy? I'm using a Savox 1256TG. It's in the range. There are several others in that price range that will fit your needs.
- Will the buggy body fit on the 2.0 t frame? No idea really :)
- Can I use my 3.2 rulux with 1/2 " off set along with mounted badlands mounted on them? Or should I stick to the truggy tire/wheel combo? You can but AFAIK all truggies already are ½" off set and use 0 off set wheels. I've tried my Rulux ½" off set on my 6T and it looks really weird.

I use both truggy wheels and Losi Super Bolt-Ons (40 series wheel). I really like the Super Bolt-Ons for bashing. Tons of grip and even though they're a 40 series tire they aren't super heavy. I can weigh both my truggy wheels and the Super Bolt-Ons if you're interested.

Probably dealt with in PM's, But have you tryed the torque control? I just started usint it in my T4 associated with a MM/4600 combo, went from wheelie happy to barely lifting the wheels and still accelerating quickly

It looks like the 8ight 2.0 t E uses plastic diff cases and cups, this is where I get nervous. Should I be?

As for the servo's, I know Savox essentially is Align servos (align just rebrands them....I fly heli's too and been happy with their larger servos). In which case, which Align (savox) is it? DS610, DS620 or DS650 the reason is, I have them mounted on my Trex 550 fbl. I can swap back and forth for now until i find the best solution. WOuld be good to use this line, since the parts would be interchangeable with my heli. I like these servos, they've been hassle free for me (except the smaller 410).

Wow, 40 series tires on your truggy! Crazy, no issues with bent dog bones or drive shafts? ARe you running 4s or higher? Thanks so much for your support, I went to the track and almost everyone voiced the same concerns that you did previously. You have been steering me in the right direction where on the Trx website.....ughhh, I don't want to talk about it, spent waay too much money on my erbe. Still like it, but it will only see 3s. I refuse to put more money into that thing.

The 6T also has plastic cases for the diffs and housings. Quite thick plastic I might add. Haven't seen any issues there as of yet and honestly don't expect to either. I have managed to slightly crack the rear shock tower due to bad landings while trying to do back flips on the track. This also caused 4 screws to bend. Nothing else has broken, bent or in any way deformed. It just keeps going and going. :)

Those 40 series has been working flawlessly. No bent dog bones or any other issue in the drive line. Using 5s and 4s :)

The servo is the 1256TG: http://www.savoxusa.com/Savox_SC1256...avsc1256tg.htm I see the price tag fell out from my previous post. Amain has them for about $80.

I have some 1/8 aluminum rc monster hybrid diffs for sale. Design specifically for the revo - pm me if interested

hey u might wanna try a mbx6t or an xrayxt8 I have seen some at some pretty decent prices if you sell the revo trade up they are beefier in everway
