Hi, I want to change my foam bumper to what the 416 or TBEVO V is using.
Will it fit the TA05R without any mods?


Thanks

supafastsupra2, pretty sure you will need to buy the diff parts seperate. I don't think they sell a full assembled diff. I could be wrong though. But check speedtech r/c. He has the front spool in stock.

Airflow, most of the local racers around me just use the Parma tc3/tc4 bumpers. Takes just a little bit of shaving on a few spots and it drops right on. Just place it on top of the stock bumper.

One mark mounts the diff high, and the other mounts the diff low. If you don't know the difference, just mount it low as this is typical for most touring cars. To find out the difference, check out one of those tuning books.

Thanks. So it doesn't matter which pt I use, triangle = lower, circle = higher. What tuning books?

Thanks.

Diff height doesn't effect roll center, does it? Perhaps center of gravity, or may have some gyroscopic effect. I'm not really sure...

Yip it doesn't effect the roll center, since the camber link, suspension arm angles aren't changed at all with a change in diff height. Do you think there's enough weight in a diff to have a gyroscopic effect.

sorry.. i got confused. what i meant was you can control how much roll you have with the eccentric diff bearing holders. because the holder is eccentric, you can position your diffs above or below your car's roll center. i hope i got it cleared.

Default CVD/Spool Vibration

Hi,

Sorry if this has been covered before, but the search function doesn't seem to be working...

I'm running a spool up front in my TA05R and noticed today that when at low to mid-speed and turning the wheels, that the front end has a considerable amount of vibration/chatter, so much that it sounds like gears are grinding. However, when at full throttle and turning the wheels, there's no chatter present (or at least not noticeable). I first noticed this today while doing a test run on my street, then figured out the behavior on my work bench, with the car up on a stand for wrenching and just testing the running of the car with the wheels in the air.

Is this just something that's a characteristic of running a spool or should I be looking for another problem in the car? I'm a bit new to on-road and have never run a spool before on any of my off-road 4wd cars (can't see why I would want to in that application ), so I don't have much experience with this problem. I do realize that just about all CVDs have some amount of chatter...I've just never seen it at this amount. It just sounds painful! Unfortunately, the track I run at isn't conducive to me going full-throttle in the turns, so that's not a feasible solution.

BTW, I got this car used and granted, the outdrives of the spool could probably use replacement. Does Tamiya have replacement outdrives for the spool as a standalone part, or am I stuck having to shell out for a whole new spool assembly?

TIA for your help.

The chatter is caused by running the spool, if you bought the car 2nd hand then it wouldn't hurt checking the spool cups for wear and while you're at it check the universal joints and wheel axles for wear too, the spool does cause more wear on those parts too.

The part number for the TA-05 steel spool drive cups is 9485079

From everything I've heard, this is just a characteristic of a spool. This same question came up in the 416 forum a few days ago. Under full power it seems smooth, but makes a bit of a chatter with light throttle...
