James Robinson awesome man!! Just keep in mind that with the locked spool your gonna be way more likely to round out the hex in the rear wheels like I did. Or a rear driveshaft could be more likely to break as well. And my steering feels much weaker after locking the rear diff.
Do the cyclones on dirt ONLY. I accidentally started doing them and lucky it was dirt. I'd never do it on pavement just because of the rc materials not being all metal. Definitely fun though. My brother has a 70 chevelle 6 second 1/8 th mile car naturally aspirated and he loves it when I hand him the remote for this. And I love it when he hands me the keys to his chevelle.
chris a you’re right it definitely is fun! Stuff breaks in rc it’s kinda the name of the game so it’s not that big of a deal. Fix it and then back at it again 😊
I bought the same locker a couple of weeks ago. Having the same issue with the rear pushing or swinging out. Don't think this car drives as well with it. I'll wait for the replacement diff.
SubNova91 yeah it definitely is more tail happy. I’ll probably still rock mine for awhile though. Who knows when the diff will show up from Arrma. They told me late August lol 😆. I knew that wasn’t gonna happen.
I feel your pain and bought the same one a little while ago it lasted about five or six runs but unfortunately that little bit of play will eventually cause the pin to snap which did happen then it just turned left I do believe it is a good fix and have since bought a different brand spool which was also a little bit more expensive at 45 but they claim to have a snugger fit so I'm giving it a try. also I have heard that drill blanks or drill bit with 2.5mm shaft tend to be stronger than the pins that are in the diff already you just have to cut to length which I'm also going to try anyways I hope this helps and Bash on
A. Smith thanks for the tip man! At this point I don’t really want to put any more money into my EXB. I think I’m just gonna wait on the lsd that Arrma is supposedly sending me
I stripped one out on mine with the open diff, had to get a set of 2 to replace one I also got the locker but haven’t used it as I rebuilt my diff to lsd again , shimmed the ring fear side and I’ll try that again if it blows it out imo go to the locker! What a pain this Truck g hv as been! I’m on my 3rd diff. Takes the fun out of it. Last run I ran 2 3s packs (6S) ans blew the diff! 😡🤬
Awesome video. I recently added my V3 diff from my outcast and it’s performing well. I made a video as well. I was told about this spool as an option. But the V3 diff is perfect. Easy fix. Of course I had an extra diff laying around. I’m glad to see yours with the spool is driving pretty well. Thanks for sharing! Subbed. Sucks about the hex. Some of proline wheels do
That's true tho about having a matching set of batterys another thing bro you should look in to and you'll get more power with better connectors ic5 at least
Yeah I need to change the connectors out on this esc…it goes into limp mode pretty easy…I think it’s because of the Deans Connectors restricting power flow…
The new outcast 8s has the reinforced wheel nuts And yeah maybe the violent and forceful donuts did you in ?? You got to admit that was a little extreme on pavement! Something had to give !
Frank Schultz I thought it was an Arrma truck. For some reason I thought it was the EXB?? my bad. You’re right. I definitely wasn’t going easy on it!! lol 😂
@@RCKnockout would like to see how well it performs on dirt or grass and maybe some bashing jumps? Still waiting for my diff to come in also 😕 right now its just a shelf Queen. Very disappointed in arrma how much wrenching you have to do to get it right !!! what they should have done .
Frank Schultz yeah it’s definitely an unfortunate situation. I think the thing is probably gonna perform a lot better on grass and dirt. I do probably need a replacement wheel now. I’ll make sure to get a video up showing it performing on grass and dirt
Great fix ,,,,,,I’m just wondering....if you lock the front diff as well It seems to me that the power would be even...on the front and rear diff causing an even acceleration,,,,,,just a thought Love your vids,,,thanks
James George I don’t think that’s a good idea to lock a front diff. Control will be horrible and the thing isn’t gonna be able to turn. Thanks for the support though 😉
Nice bro Atleast the diffs sorted . But now the tyre 🤦🏻♂️😅 OMG . It’s not your day bro . One problem after another. I run the Katar wheels on my kraton and Mojave they are perfect 👌. Light and durable. Well so far no problems. On loose gravel your wheels will hardly strip out but with locked diffs on tarmac will strip like cheese 🧀.
Adrenaline Ash RC yeah hopefully I’ll get the thing up to 100% at some point. It’s kinda trial and error. I did end up just buying another set of the copperhead 2 tires for it. Just waiting on them to get here
So... what's the update here. Do you still stand behind this locked rear setup.. or now that Arrma has fixed the issue's with the diffs, will you go back (or have you already) to the stock setup?
I don’t stand behind it….I was tearing up wheel hexes because of it…..I also don’t stand behind the open diff or the limited slip….honestly I wish I hadn’t bought the EXB at all…worst rc I’ve ever owned…breaks every time I have it out….I might make one last attempt to fix it….I might try an aluminum diff housing….my gears are getting destroyed each run even with proper shimming….it’s possible that the entire case is flexing on big landings….not 100% sure though
@@RCKnockout oh man bought myself the regular pins I think its like qty.10 for 3$ JJ CUSTOMS my local hobby shop is working on making hardened pins but ever since i replaced them ive done 2 8s bashes to test it out and so far so good
So im running a 19t castle 1717 motor on a mmx8s and im getting some rear diff noise. How does that diff handle bashing? Also just got a set of proline mx38s belted tires coming in the mail.
@@rungunrc1306 I don’t. I need to put a link to it in the description. If you go to ebay and type Arrma EXB diff locker spool a bunch of similar options should show up. I think this one cost around $30 maybe another $5 for shipping. I think the brand is called src or something along those lines
I have these same lockers. My problem is the main gear and input gear shredding teeth. Have u had that problem? I use proline street fighter tires for on road bashing, less grip than off road tires.
Paul Clancy the diff lock isn’t why I blew my main gear and input gear, they shredded 4 min into my first run. Then I bought the lock and shredded the gears again. My next solution is to never use spiral gears again. I had spiral diff prob with my V3 Kraton and Mojave changed them both to straight gears now they’re cool
@@99ville that is hilarious, I have exact opposite experience, i have box stripped ring gears to finally use spiral mojave in front of my v4 kraton and been goid so far, ive only had problrms ring gears with the kraton. I own few arrmas .
jessiejames the front has a limited slip so the front doesn’t need to be touched. I locked the rear diff because Arrma did not assemble the open rear diffs properly from factory and it’s really my only option as of right now to get the rc running. Arrma is sending me a new diff to put in the rear but it’s on backorder. Who knows when or if it’ll ever show up. So there are some like me who have had this issue. Some diffs were assembled properly others weren’t. They shoulda done a recall
jessiejames I assume you’re talking about the rear diff? There should be 3 shims on either side. But I think in the manual it says it should be two large and one small shim on either side
Here's me crashing my EXB and ended up bending the tower and breaking the pin inside of that spool and damaging that spool as well. th-cam.com/video/uadkGyp_VVc/w-d-xo.html then ended up putting back the old gearing (brand new) and tried running on 4s as to not grind them but end up doing so regardless in this vid (did get some double flips out of it though) - th-cam.com/video/fH7aQ6Bg2YM/w-d-xo.html cant wait for the diffs from Horizon so i ended up buying another one of those LOL. You should be ok running, just land right and you should be able to make that last hopefully.....
Appreciate the vid. But this is terrible. Does Arma really expect its customers to come up with solutions to their faulty diff designs?? The EXB cost $470. If you don’t have spare electronics lying around it’ll cost close to $1K just to get it moving. Then we need to play trial and error to make the diffs work right?? This launch has been a complete failure for the EXB. So glad I didn’t run out and purchase this RC.
pewterngold I’ve kinda done mine on a budget. I probably have $750 all in on mine not including the cost of the locking spool. Its definitely been frustrating. I think Arrma was just trying to get as many EXBs built cause they were on preorder and in the process they made some sloppy mistakes. To be honest I would be kinda concerned about buying any new release Arrma just because they’re trying to mill them out as fast as they can to keep up with the orders. That’s where mistakes are made. I think they need to take it back a few notches and really focus on quality control cause issues like this could really hurt their reputation if they continue to make mistakes
RC Knockout....I agree. I’m just having flashbacks. I have an early version Outcast that was nothing but one big headache with all the shimming vids I had to watch to remove the slop inside the diffs they were shipped with. I don’t think Arma addressed that until the V4 Outcast but I might be wrong. Anyways, I’m just tired of giving this company a pass on stuff like this. They take our money and then they’re like... “ try this or see if this will work”. I think they knew the rear diffs were going to be an issue. There’s another TH-camr (well respected) who said that when he picked up his EXB from his hobby store, there was an Arma rep there who suggested that he upgrade the rear diff to an lsd. If that’s true, than shame on Arma if they knew the open rear diffs were going to fail.
pewterngold I’m not sure if they knew they were gonna fail but they definitely didn’t shim some of the rear diffs properly which caused damage. It doesn’t sound like isolated cases either. Sounds pretty wide spread. I guess it just comes down to luck whether or not you receive a correctly assembled rear diff?
pewterngold yeah I was looking to buy a Arrma just to get away from cheap diff gear problems all that’s money to be fixing on it every time I wanna play with it is frustrating true it’s a hobby and things gonna break eventually I totally agree Arrma needs to step up their game they should no better helI can buy 2 cheaper RCs that holds up better than this this.
@@k9chance250 And thus the reason I will not purchase another Arrma until they figure out their drive trains and scale incompatibility. Such a good machine, but there are too many faults right now. Other brands although not perfect, have figured most of these issues.🤘
That is the very part that ruined my Mojave😒. Now, Integy billet gear boxes properly shimmed. M2C out drives and axles all around. 30k 500k 30k oils and now all is good👍 -keep it loose if a off-road basher😁
I'd try to fix it properly. What's the problem? Cheap pot metal? Well, it is Chinese right? Maybe you just got a bad one. You won't like how it handles with a locked up Diff. That's only going to constantly stress the rest of the driveline. Why not do the front too and really make it a mess. Usually it's the front that blows.
