my LHS sells kyosho inferno diffs and xtm diffs , which is better??

wat diffs r u guys using in ur hybrid bulks??

Thats odd and hard to believe! Emaxxter, a poster on TRX busted a HB Lightning diff in his Hybrids a few days ago

Shimming the diffs make the most diferrence. I am using Ofna 8 spider diff on my gmaxx and I still have to strip one of them. Of course, I shimmed them nicely too.

I agree with Lito. 1/8 diffs in a metal case that are shimmed properly should not have problems with the systems we are running.

I use these in my FLM hybrids.

well i opened the diff and the ofna titan spider gears were all broken into tiny little peices unlike the inferno spider gears where the gears stripped , so i put another set of kyosho inferno spider gears in the diff and this time i shimmed it so it has a tight mesh , where it was hard to turn by hand, its been 2 runs now and im not having problems with, i will take it to the track today and will see what will happen.I passed by my LHS to see wat diffs they had , the xtm spider gears looked like they were made of the same material of the titans ,so i didnt get , so i bough a complete diff of a strange brand for 15$ and was planning to useit if the kyosho inferno spiders fail again , but it didnt so far was expecting it to strip the first 5 min

if all fails im gonna get the aluminum diff case and hot bodies diff , , anyone running this setup??

[suicideneil]

Hot bodies diffs + UE ultralite cases, about as bullet proof as you will get apart from ofna 8 spider diffs = my setup.

I broke the output shaft on a hot bodies diff the other weekend

[suicideneil]

Vandal. Was it the original shaft with a cup attached, or one of Mikes shafts that lets you use other cups etc?

[RUSTED]

well after shimming the diffs so it has a tight mesh i havnt been having problems with the spider gears stripping or breaking , but now i noticed that my car tends to go to the right under hard acceleration , its not from the steering i think it m8 be from the diffs , wat could be causing this problem ??

[suicideneil]

Torque steer ftw!

If it wasnt doing it before though, I would check over the steering and the toe-links to make sure everything is right & proper in those departments.

Mine does the same though, its just a natural thing as the truck leans to one side under power- like the way a txt-1 does only not as bad.

[JERRY2KONE]

Engineering wise that is somewhat natural due to the torsional twisting effect of the motor because it is mounted from front to rear in the vehicle. It should not be too noticable though being that the vehicle is pretty small. In 1:1 dragsters it can actually throw the car into the wall due to this physical act of mechanical nature if it is not compensated for. It sounds to me like since you shimmed the diff properly you have a very tight setup that is near perfect, casuing the vehicel to pull to one side.

[Kcaz25]

Some guys on the TRX forum actually had the same problem after installing those diffs I dont remember what they did about it. I'm pretty sure there is more to this than torque steer.

[RUSTED]

well im still having diff problems , they usually last 2 weeks then strip , i think it m8 me cause of 3 things , either its because 1)its too heavy (FULL flm parts arms chassis shock towers .....) 2) the diffs i used were from an ofna titan , used infernop and a non brand chinese diff so it m8 me cause the diffs i used r weak 3) coz im using ofna titan cups with spacers


the solution to the first is buy flextek arms and g4 chassis , for the second is buy lightning hardened diffs , for the third is buy the adapter to use emaxx cups


wat do u think is the problem , anyone used to have the same issues ?


thanks

[mkrusedc]

Not sure about the weight issues. Alot of us have heavy trucks without a problem. Just be done with it and get the HP buggy diffs and you will be fine. I have beat the snot out of my truck without a problem.

[RUSTED]

well i just ordered a set of hardened spider gears from the hot bodies lightning to try it cause i coudnt afford the full set cause i had to get some other stuff for my other RCs , but can anyone help me on how to shim the spider gears , cause im not sure of the way i do it

Here is a pictorial thread on how to shim a Maxx diff:
