FLM Hybrid Bulks
 

Hey guys,

I am trying to put together the hybrid bulks but the shafts that connect the wheels to the differential wont fit together. Only ONE fits at a time and the other one will not..!!!

What am I missing??

Thanx for the help

Its a totally stock emaxx btw.

Your sliders won't slide together is what you saying?
I know they are kind of go together different ways.
Did you rotate and try all the ways?

yes, i have tried almost everything, including rotating them, also tried to connect the shafts to the thing inside the bulks first and then tried to slide the bulks together...it doesnt work either way. :(

did you swap sides? I have seen them not work if inchanged.
If not I don't really know unless you mashed the end some how with out knowing.

yes, I tried that too but didnt work. And, all the parts are in pretty good condition, meaning nothin is mashed or anything. I am not missing any part or anything right..!!!!

Is one of the parts oval just a smidge. I don't know.
it is a good one though. I would take it off the truck and try to wrestle it together so you can figure out better. Cvds are a lot stronger.

If you are meaning the stock pins won't go in, it's because the Hybrids have a tad bit more of an inset. Meaning, the diff shafts don't stick out as far so you are going to have problems getting those pins in, one will go, but the other will be too far in on the other side for the stock pin to go in, it'll be at an angle and won't slide in. If i'm understanding you right.

I am having problems with the stock part inside the differential that you connect the shafts to, meaning I am using the stock ones right now and not the cvd's or UE's. Only one shaft will connect properly with the screw (l-key head) with that part inside the differential. The other side will not connect properly (the hole doesnt allign and doesnt come far out of the bulk for me to connect the shaft properly with the screw).

I am not sure what exactly you call that part thats inside the differential. There are two, one is a lil big and other is smaller.

Hopefully, I made some sense explaining the situation. But it looks like the FLM bulks should connect fine with all the other stock parts..!!

then yes, what i said is correct, it won't allign because the hybrids are a bit different. You would have to put the shafts on first, then put the halves together, if that don't work you will need to get cvds. Are you running stock otherwise? can you send a pic to me? I may have a set that I could let go?

yes, I am running pretty much stock, besides rpm a-arms and 7 cells (IB3800's). I will try to post a pic tonite when get home. I have tried to put the shafts together first and then slide the bulks, but it didnt work either, the end that connects to the differential is a lil thick to go through the bulk's hole. I will try to force it today and see if that works. I thought the flm hybrid's were supposed to work with all the other stock parts..!!!!

What kinda condition the cvd's are in, P.m me with details/pics if you can.

Ok. here is the problem ... They are fit for 1/8 buggy gears. So that's why they don't work. I see the problem now, the cvd's won't cure the problem. DO NOT FORCE them, they will never go. You could mod it with a dremmel too, take very little material off at a time and see if that works. otherwise, sell them on ebay and get the ones you need. If you are still interested in the cvd's pm me and i can send pics or something tonight.

So you got the Hybrids and not the combos is what happened? If so, newuser is right. You need, either A: get the combos, or B: get 1/8th scale gears. I would choose B because there gonna last unlike the stockers.

hmmm...alright, then I guess I will get the gears. what do you mean by "combos" squee..!!!

And yes newuser, send me the details/pics if you can for the cvd's.

FLM makes what they call the FLM Combo bulks and the FLM Hybrid bulks. The Combos are simply a bulkless design for the stock gears. The Hybrids are designed for 1/8th scale gears.

there are two kinds. hybrid bulks, and combo bulks. combo bulks are designed for stock gears, hybrids are for 1/8 buggy gears....if you go to the store you'll see both with discriptions. the hybrids state "uses 1/8 buggy gears". If you're running stocks gears, the combos are the same as the hybrids but use stock gears instead of 1/8 buggy gears. You wanted the combos...

The combo bulks take the stock diffs while the hybirds take the 1/8buggy diffs. It is 30 bucks difference in price as well.

hmmm, I see what happened. Thanx a bunch for the help guys. Now, I think I would be better of getting the gears instead of replacinvg the bulks, coz I am gonna be going brushless anyways (7xl, 9920 as squee suggested in my other post). Correct me if I am wrong please.

Now, with the gears, is there any specific brand or anything else I should be looking at..!! The goal is reliability since I buy once and cry once :).

I would get 8 spyders, 6 will work too. But the 8's are better. go to supermaxx and check ebay, there are some there now. or go to Unlimited Engineering and shop, go to differentials. HB's work too, Squee knows what kind to get. My cvd's, i'll send a pic tonight.

The 1/8 diffs are much stronger. It is a good idea to get the gears instead of bulks. Less damage in the long run to wallet. I would go with the 8 spyder setup as well or hb diffs. If you get the set of ofna off ebay get a set of ue diff cups for I have damaged a cvd cause of the length difference.

Go to ebay and here's what you need. type in this number in the search 120002902568 or here's a link to what you need http://www.unlimitedengineering.com/...ore/13543.html
You may be better off going to UE and build yourself as then you would know how they are built. If someone else has built them, you're not sure what you're getting

excuse my ignorance for being a newbie, but whats the diff between spyder 8 and 6..!!!

It's ok, i'm still kinda one myself...anyways, the number of inside gears and strength, hence the names. Go to UE and you'll see. the 6 use the plastic cups, the 8's use the aluminum. Trust me, you want the eights for the money.....here is a link 6's http://www.unlimitedengineering.com/...ore/13542.html
8's http://www.unlimitedengineering.com/...ore/13543.html

local hobby shop has a set of robinson racing diff gear set for like $35. is that a good one or what..!!!

You can try them, but "buy once, cry once"! If you plan on getting the set up squee suggested, I would stick to UE, in the long run ( and you'll learn this fast ), getting the UE's or HB's from Mike, will save you much heart ache man, ask anyone here! I have gone cheaper many times and burned my self money wise. I jsut went thru my receipts, i actually lost over 750.00 because I went cheap and then got the "real" stuff.

newuser, how fast is ur truck? have u had a chance to check the speed? Ur setup looks pretty good.

Hustler, go with the HB 6 spyders. There superstrong and replacement parts are pretty common since the Savy uses the same internals. The HB can't be beat for the price. Oh, and don't get the Pro versions, get the standard Lightning's. They have the standard gear ratio and not the truggy gear ratio. If your gonna run 12 or 14 cells max, then yes, the 7 or 8XL would be my choice. 8 if you want more runtime...

can u post a link for the hb's..??

Also, isnt 8 a lil slow then 7xl..?? how much runtime penalty are we talking abt here.?

Not sure how fast. 40's i'm sure... i think these are what squee is talking about... http://www.rc-monster.com/proddetail...HPI_BUGGY_DIFF as far as run time give or take 5-10min i would guess. i would go with the 8 myself, but not quit sure on the run time difference.

HEre you go hustler.

Btw where abouts you live north of me?

Haha, beat you to it coolhand! sorry....

I am in Gainesville squee..how abt u? And thanx for the link newuser. U guys r very helpful.

so with http://www.rc-monster.com/proddetail...HPI_BUGGY_DIFF I wont have to get anything else right..!! I mean the stock shafts would fit right in and the bulks would be good to go as well..!!!! I dont see where the third shaft would go.? Does this diff have a hole on the side for that third shaft?

Well I live in Lousiana....but maybe you meant Leroy? He's in Woodford...

No, you need cvds all around with the buggy diffs. MIP and UE are just about the only ones you can use. CVD's and the gear sets are all you need though.

Well, Sorry for the confusion, I meant coolhand as far as the whereabout goes.

Would I also need the center drive shafts as well..?? or the stock ones will do with the hardened diff..??

Thanx for the input guys, I will keep you guys posted occasionally as I progress.

I sent you a pm, you will need centers as well. i found some stuff for you you may want to check out.

A can of worms
 

Alright, so I thought this was gonna be easy. Well, I guess, I was wrong. I got the hardened diff gear (Differential: C8084-1, Pinion: C8030). Also got the cvd's (http://cgi.ebay.com/ws/eBayISAPI.dll...ME:L:RTQ:US:1) to go along with my hybrid bulks.

Now, a couple of problems that I ran into. First, I didnt get the bearings with the pinion (center shaft), but I can grab them from my local hobby shop tom morning. Secondly, the cvd's arent long enough to fit in the differential..!!

What did I do wrong, how do I fix?

You guys have always helped.

Thanx

And the hybrid bulks, diff etc are gonna make the truck "very" heavy. I hope I can beat the 3.3 after I am done with this thing. (7 or 8xl with 9920 is the plan for now).

It shouldn't make your truck to heavy. What diffs did you get?

http://www.rc-monster.com/proddetail...HPI_BUGGY_DIFF

I got it from the local hobby shop.

Those should be fine. They shouldn't give you any length problems.

Well, the cvd isnt long enough to go into the cup thats attached with the differential. I am not missing any part right?

Also, what else would I need beside the bearings for the center shaft. The center shaft doesnt seem to connect to center cvd very well either coz its a lil bigger then the stock one.:019:

I can post pics if that would help.
