sounds like chatter from your front drivetrain. the spool causes this.

Double Quattro

edit: Sorry Hebiki beat me to it but here goes anyway:

Maybe the inside wheel is spinning because of the spool. I have just run with a spool for the first time and I thought I heard that very thing when accelerating HARD mid corner.

It makes sense to me because you have zero diff action. Try the stock diff again and see if the vibration goes away. I think 4.5 is a bit MEAN for a stock TA05

I think you 2 are right on...make it 3, my buddy who has the 415, MSX, MSXXX EVo3 Evo 4....etc that deal with Tamiya for so long saying because I was using the SPOOL....I have to get a shorter CVD bone...NOW, that really make sense because I do see Tamiya have 136 different length of CVD bone for "SOME" reason...and that is WHY....

I have not open the diff case and measure, but I can tell, the end of the bone right now is TIGHT, but not binding...however, with the 4.5 motor power, and when the steering is turning...that little space will not cut it...

Not to change subject too much, but when you guys run the TA05 with a 27-turn motor for a stock class, do you run one-ways or spool setup? Does one tend to work better than the other with the slower motors?

Hebiki, if you are selling your MRE after the beginning of July, I would be interested in talking a look at it!!!

So it was my first ever rubber tire asphalt race. I ran some Sorex 28R's on Tamiya rims(no offset), 2 degree camber all around, yellow front springs, red rear springs, toe in front and rear, rear 2 degrees, front 1 degree, and 6mm ride hieght. Car was quite loose off power and pushed on power that was until my tire glue let go.....

First question, I'm still new to racing not even one year, what kind of droop setting should I be running with this car, because I thought that might be my issue. I know it could be a number of things, but any help on setup would be great.

Second the Tamiya rims I used were clear ones and I used CA glue on the tires and they came apart in the A main, first A main I've made it to in Stock needless to say it was a last place finish, but anyways glueing the tire should I sand the rim first or anything else like that?

Any help would be greatly appreciated.

One other thing right now the car has diff front and back with a centre one way, I have a front oneway, but have never tried it. Our track is 100 ft by 50 ft and pretty open, would a front one way work better?

Cutwo,
If you measure from the top of the axle to the bottom of the chassis, I run 23mm in the front and 25mm in the rear. I believe that works out to about 4.5mm in the front and 3mm in the rear, depending on tires, It's critical that the droop is exactly the same from left to right.There was a great article by Dave Jun in one of the RC magazines last month that is very helpful, I try to find out which one it was, I have so many!
If I run diff. in the front and the rear I run direct center pully not one-way. Only use one-way if your running a one-way up front.
If you run a spool up front run the direct pully also and try and use the least amout of dual rate in your controller as possible or turn down the steering endpoints, the universals will start to bind if the throw of the steering is too extreme. It's actually better to learn to drive using the throttle on and off in the turns to get the car to swing around vs. pushing the servo to the max to get it to turn.Also using the steel outdrive on the spool will cause more vibration, so I use the delrin outdrive with the MRE coupler. You just have to grind a little of the bottom of the bulkhead for clearance. My little secret!
Hope this is of some help to you!

carking... it depends on your driving style. a properly set up spool car will be just as fast as a oneway car. but with the added benefit of using brakes (just in case).

Looking for after market hop up for TA05 bulkhead...
Aluminum bulkhead got one?

R/C Car, May 2007. I had all these droop questions too!

"SQUARE" i think is one company that sells aluminum bulkhead and try Speedtech they might still have some

3Racing make the bulkheads, but you got to check the online shopping sites as they make them in batches and when they are sold out, you got to wait for more.... they do make belt tension adjustments far easier though.

Xenon makes the TA05 bulkheads also.

My experience has been that a spool is easier to drive on low traction surfaces and tends to make the car tight when
the traction comes up. The one-way works well on medium to high traction smooth surfaces. If you can get the one-
way to work, its usually a little faster because corner speeds will be a little higher.

Of course this all depends on driving style.

The spool tends to be better for an agressive driving style (drive deep into
the corners, brake and throttle out).
You can't lay into the brakes very hard with a one-way. So it favors a
smoother driving style that uses less brakes.

Depends on track and driving style. My daughters car uses centre and front one-way on tight technical tracks. One track is carpet, the other asphalt.
I found one-ways harder to drive, it took me about three months to equal my diff lap times when I swapped over. My daughter loved the one-ways from day one and found extra speed, mainly thru carrying a higher corner speed.
She TQ and won the club round (27 stock) for the first time last sunday, including beating me. She hasn't stopped bragging yet.

Thanks for the input, I will be trying some things with the one-ways this weekend.

I was also wondering if anyone could tell me where to find info on the Tamiya B3 tires; stuff like optimal tire temps, what track temps is runs best on, etc. I got some tire warmers and I need to find out what temps to stop heating the tires at.

Hebiki, you going to be at the Tamiya track anytime soon?

yes sir. ill be at tamiya this sat. got three bodies to test. ill bring an extra box of B3s for you. it has the temp chart on there.
