Switch to 48 or 64dp and you should see the noise go away
I'm running 38/100 64 pitch. I will give it a few more runs to see if it will work its self in place. Thanks of the tips guys

After finally getting a TA-05R, I club raced it in 13.5 rubber and got the TQ and win(out of 6 cars). The car's first run was a race, so I want to get my car better for the final Hurrican race at Trackside in WI. After owning a TB-02, the weight distribution seemed better than the TA-05. The car seems heavier on one side with the same preload on the shocks. What should I do to fix this(I'm hoping it doesn't involve weight). Also, what should the droop be set at with a normal gauge?

mjderstine: 64 pitch will go on the TA-05, along with 48 pitch

Waltrip55- The brushless system is heavier than the STD ESC so chances are the weight is not even from left to right. To check the left right balance I use kite string or equivalant, loosen the center screw on the front and rear shock tower bulkhead wrap the string around both screws a few times and visually see if the car is level. I've also put double back tape on the bottom of the chassis to hold a small bubble level on it and make sure the bubble is centered.
Just my @$
mjderstine- www.speedtechrc.com has Xenon spurs and pinions which I use quite a bit. Depending on what system your using. 102 is pretty std. But if you run Brushless sysytems that require 5:1 FDR or lower, 96 spur is a better choice. I have a large variety of pinion sizes for all my needs. 25-51. Of coarse you don't need all these pinions but what FDR are you looking for? For 19turn if it's a torque motor 5.5 is good but RPM motor 6.5 might be better. This all depends on the size of the track you run. Motor rpms should peak close to the end of your longest straightaway. If you have a temp gauge then motor temp would be best to get the right FDR.

i just got back from the LHS and got a 104 spur and a 32 pinion 64p, my math says 104/32=3.25. is that the drive ratio and how does that compare to the final drive ratio calculation of 5.5.

i am running a 19T orion core stock motor. i will be running the car on an oval track and a road course. so i will probably want a different ration for each. speed on the oval pick-up/accell on the road course


thanks for the help.

you need to multiply that by 2.25 which is in the internal ratio of the TA05.

mjderstine,

The 32 tooth pinion gives you a FDR = 7.31 (3.25 x 2.25). You'll need to go back to your LHS and get a 42 tooth pinion. That gives you a FDR of 5.57.
Actually, you should buy a range from 39 to 42. That'll give a range of FDR from 6 to 5.57. The Orion 19T usually likes something in that range depending on track size. Good luck.

so would i multiply the 3.25 by 2.25?

that would get a drive ratio of 7.3125?

im getting confused guys, sorry, but this is my first mess with gear ratios.

editawesome, thanks for the help guys, i guess i'll save the 32p for some really tight tracks. or just return it...

yes to determine Final Drive Ratio,

take the (Spur / Pinion) x Internal Drive of the Car.

Thanks for the tip. So, my preload on each shock should be even regardless if the balance is off? Also, what should the droop be at(I know...2mm), but what should it be on a normal gauge?

Set the pre-load so that the ground clearence is the same on both sides. I have almost zero preload on the motor (Novak GTB/13.5) side in the rear to keep the clearence at 5mm.

i have a 104 spur and a 42 pinion that gives me a FDR of 5.57 now.

ill be at the track wed to try it out at practice and let you all know how it handles with the 19t pushing it.

That's how my car is right now...but doesn't seem right for some reason. Maybe because I've never had the weight distribution this off

Yo guys, are there any fitment issues with a standard TA05 oneway on a TA05R?

Nope,
Only difference is the pulleys. 05R comes with wide pitch pulleys.
Standard Oneway hop-up comes with the standard pulley.
You can upgrade the pulley to the wide pitch if needed.
