twin force center diff.

[jollyjumper]

thanks promod,
can you adjust toe-in/out on that steering?

[jollyjumper]

mike, could you make a sprocket that fits onto a mp7.5 diff?
this is the stock sprocket:

[Promod]

You can adjust toe-in/out by adjusting the rod ends.

Thank you,
Promod

[jollyjumper]

ok, thanks.

I thought about a chain drive slipperential too, Jolly :)

[jollyjumper]

roflol, i think it would work nice.
i'm always exploring ideas.
i need someone that can make the sprocket.
and i cant draw it aswell, the teeth.:mad:1 :mad:1 :mad:1 :mad:1

[jollyjumper]

promod, yet another question, how does the thunder tech racing stuff hold up?
is it good quality?
thanks, mike.

[jollyjumper]

this chassis would be nice for making center chain drive diff.
i dont want the diff to be bigger in diameter then the chain drve sprocket is now.
it sticks out 12mm below the sides of the truck's chassis plates.
even with a small 44 tooth spur that distance will increase.
so i really want the chain drive slipperential or w/e you'd call it.
here the nice thundertech racing chassis:

[Promod]

Thundertech stuff seems to be good. Have four or five of there clod chassis and they take some abuse. Although my one ripper-pro clod chassis did crack a side plate an a bad high speed flip. Anthing can break,but I would recommend the thundertech stuff unless your going to get real crazy.

Thank you,
Promod

i'm not going over 40miles an hour really, so i guess it should be fine.
i think can do my diff upgrade easier on the thunder tech enforcer.

[jollyjumper]

got my F/R diffs, 4.3 ratio.
dont really know what to do, get a motor that will run nice with the 4.3's in there or get 3.31's and get a motor for the ratio that would give me?
any advice?
ratio will be 25/1 with the 4.3's. with 20T motor pinion.
need to shim the diffs, got shims on the way, any tips you could spare?

[jimbob]

bring up old thread :024: but i too would like to know about the centre diff and if you got it running :004:

im gunna try and get some designs drawn up in cad soon

[jollyjumper]

i'm still thinking about it but not working on it right now.
i would like to make it with the chain drive, the hard part is the sprocket.
i would also like to use the thundertech chassis as the center plate is longer, wich is needed. i'm kinda holding of since this project may be more difficult then doing 1/8th nitro conversion, wich i plan to do 2 of soon. most likely i wont be able to make my own part so i'll have mike do the machining.
if you draw stuff defo show it of here. maybe we can work together on this?
thanks, mike.

[jimbob]

ok kl... i will try and get some measuring done.. i was thinking of running the lightning centre diff as i am converting to those diffs anyway...

looks like you could use that spur pretty easy (not sure on pitch) or swap it with a 32p spur
im currently using this Carbon Fibre chassis - (cant find like :013: ) but i may use the stock tranny plate as it is more solid

[jollyjumper]

direct drive? then you need plastic spur for the diff, steel does not work, eats pinions. look in the shop here in gears and tranny section.
i want it to be like the stock trans, but with a diff in it.
