IRS only makes a solid front axle for the TC3
same thing as what a spool is in a drag car

John,

4 mm, is this the asso or the yokomo one or isn't there a difference (I don't have a TC3).
Tech Racing makes a very strong 6 mm one way:

the yokomo one has bigger bearings and is less prone to one way blow outs. also looks nicer since it is anodized blue.

Bigger one way bearing or outdrive bearing?

I am using it on a GPM center one-way and swap it out to an IRS alum shaft. I don't have any problems with either setup other then the pin for the mount has a bit too much play, but I can live with that. Does not seem to affect performance.

hey, i havnt checked this thread in a few days. i see you are here at rctech now sharkman. cool

dave, the irs inputs are nice, very light.

does anyone know who makes the titanium stubaxles for the tc3, i remember seeing them somewhere but cant remember. this seems like it would be a great rotating mass reduction.

Barry-Thanks for the info. I am using the Associated TC3 one-way. The shaft size of the outdrive is 4 mm. The one-way bearing seems to be holding up well.

Northerner... thanx for the correction. I couldnt remember for sure what all IRS offered. Shark... did you say a GPM center one way? Is that the one that replaces the rear or front drivecup for the main driveshaft? I have seen one like that, and wondered who made it. I currently run a Niftech Ti shaft...it is my second one... but they arent bomb proof. I have twisted one before, running modified on a high bite asphalt track in MD. No hits or anything like that... just alot of torque i guess is what did it. It had a persistent wobble near the end where it attaches to the rear gear adapter. Is the ASC aluminum one i have seen mentioned as an update, any stronger? Or is it hollow as well?

Thanx Spaz... i got one on order. There is nothing i hate more than a wobbly spur gear when i am trying to set gear mesh on 64 pitch gears! "its tight on that side...loose over here on this side...GRRRR" Hopefully it will put this to an end for me!

DaveW,
The GPM one-way is mounted on a steel input shaft with the one-way drive cup being aluminum. It is mounted on the rear. It looks pretty durable.
I am still using the composite main drive shaft and I think it is has some wobble to it. Have been thinking of getting the aluminum one. Anyone have any thoughts as to if this is worth the expense?

sharkman-i definatley like the aluminum ae shaft. it is not perfectly true but it sure is alot better than the carbon ae ones. the only thing i dont like is the roll pins that come in the ae aluminum shaft, because i run the irs input cups so i think i am going to put irs pin cusions in the shaft instead for better wearability. maybe ill get some this weekend when we go to ct.

dave- you wont be dissapointed.

So from reading this thred so far if your diff by itself will not spin freely in the transmission cases you need to remove some material from where the bearings ride, correct. If the diff spins freely and the input shaft spins freely but when assembled gets tight you need to remove one or more shims to free it up, correct. This thread is going to be a life safer. Just switched from the XXX-S to the FTTC3. Not going as fast but a lot more consistant and easier to drive. Just need to free up the drive train and get a little more speed. Hopefully this will due it.

I am also running 64pitch, what is the biggest spur I can run without major chassis modifications. I am currently running a 104 with no problems but would like to go alittle bigger.

Later,
Tony

Crash-you have the right idea on gear mesh. More than likely you only need to remove one shim from the input shafts.

A 112 spur requires chassis and motor cam mods to fit. I suggest sticking with 104 or 100 spur.

Has anybody tried the heavy duty oneway for the TC3 from yokomo? Comments/impressions?



SP-3638-6 TC3(Electric) Heavy-Duty Front One-Way Unit $58.50
Featuring larger one-way bearings than the standard front one-way, expect much better durability from this heavy-duty unit. Compatible with the Electric TC3 only.
