Hows it going guys. I was wondering if you could help me out with a problem that im having with my 05.

What would cause the car to be extremely loose in only one direction (left turn)? Coming off of the straight into a left sweeper causes me to spin out as soon as I back off the throttle and start turning. It looks like the car literally pivots around the left front tire.

I also get something like "torque steer", if I full throttle from a stop or slow roll the car will pull violently to the left.

I have a little bit of understeer on all right turns though.

heres some more info for you guys - the track is clean asphalt. F/R diffs (no one-way), novak 4.5r, trf yellow dampers w/ 60wt (brand new, but the car acted the same way with the stocks), hpi belted 33r tires. -2 rear toe, 0 front toe, -2 rear camber, -1.5 front camber.

Could the diffs be the problem? maybe too tight or too loose? The rear diff is starting to feel notchy.

Default First time with an 05

Hi all

I was just loaned a 05 for the upcoming Tamiya race at trackside. I setup the car not knowing whats what, and put it on the track. IT WAS AWESOME !! I never had a car handle so well the first time out. It would take me 2 to 3 days to figure out a setup on my TC3! At this rate, I may have a problem going back to it after the race is done.

check the bearings on the front right hub, if they're locking, that'd cause it to pull left off power

I'd also check your droop settings are equal, that can throw any car off centre.

@k808:
Sounds like you have something binding...i'd check whether the inner edge of the front wheel rubs against the ballcup that is attached to the kingpin (in other words, the c-hub end of the front upper link), especially if you run tires wider than 24mm.

Use the white spring in front and the yellow at the rear.

Match the damper holes/oil with the springs.

Use less dragbrake.

Check the ride height front and back.

Use less % stearingmax.

Succes!

Bearings (most likely) . I had the exact same problem with my FK05. I just found out the other day and now im gonna change all my bearings. Its probably the rear right hub.....thats what mine was.

Agreed, I'd check both the bearings & recheck your droop settings all around, those things can make most any car pull to one direction or another(happened to me plenty of times)....

105 / 49 = 4.821 FDR
105 / 48 = 4.921 FDR
105 / 47 = 5.026 FDR
105 / 46 = 5.135 FDR
Thanks a ton! Have you had any experience running silver cans in the TA cars, or mainly mini?

Does anyone know if Tamiya part#: 3454395 (Direct Center Shaft) can be used with the TA05?

I don't believe so. What are you trying to accomplish?

Hi All

I have a TA05 and have been racing it for about 5 months.
I started racing with a standard kit with no hop-up's and do pretty go for a beginner in racing. I have in time put some hop-ups on to it from 46mm Assembly Universal Shaft on the front and rear, front one-way, centre one-way and the TRF Damper set with a set of On-Road Tuned Hard Springs also a LW Carbon Lower Deck.(weight 1.648kg)

The class that I race is the 540 group(Spur 68 and Pinion 35= Final Drive 4.37).

For the Summer Nationals at Fairy Meadow-Australia, I raced in 27 turn stock (Spur 72 and Pinion 22= FD 7.36).

I am now building a new TA05 for the TCS event in Sydney-Australia. I'm starting with a LW Carbon Lower Deck, A- Parts Carbon Reinforced Bulkhead, K- Parts Carbon Reinforced Bulkhead, Reversible LW Suspension Set, 46mm Assembly Universal Shaft, Aluminum Motor Mount, Carbon Centre Plate, Titanium Screw Set, Aluminum Racing Steering set, Carbon Steering Link, Aramid Drive Belt, Front one way unit, Center One Way Set, TRF Damper Set (Fluorine Coated) and for power I'll have the Super Stock Motor RZ- Lay Back Brush. The reason of getting the carbon part is to get it as lite as possible.

That for starters in this build and will post some pics later down the build.
