TA-03 question

Recommended Posts

Okay, perhaps a bit silly, but did you try searching for 0.4M pinions? I get over 20,000 results on Google... :)

Pinions to fit 2.5mm shafts are everywhere.

Not any for 3.2mm.

Might just have to change to the black gears....

I finally got the TA03 running.

I swapped out the white Pro gearset with the black 0.6M set, as 0.4M pinions are too hard to find.

Took it to the track today, and it's way undergeared.

I was running a 17T motor pinion at first, then swapped it out with the 20T pinion from my M03, which gave a slight improvement.

(I forgot to take the other 23T I have. <_< )

So a few questions.

What is the transmission ratio?

What spur gear options are available, or is it limited to the stock 43T?

I need a final drive ratio of around 3.5, so what are my options?

I looked at Gearchart.com, but they don't have TA03.

Going by the TA04 chart I'll need a 26T motor pinion.

BTW, the belt pulleys are 15T, and I'm running HPI Vintage tyres with an outside diameter of 64mm.

Any help will be appreciated.

Thanks in advance. :unsure:

TA03 gear ratio chart.

The belt pulleys willl not affect the FDR.

After doing the calculations, a 28T motor pinion will only give me 4.25 FDR. <_<

Hmm, what to do...?

28/43 will give 4.25:1, but will that fit though? The list shows all the possible combinations. There may not be enough movement in the slots or the motor hole to get a pinion that big in there.

I'm getting about 60km/h from 14/43 with 2S Li-Po and 5700Kv brushless, with crazy acceleration.

I found that the 21t pinion just cooked a silvercan, I used a 21t single wind motor with good results, but a brushless set up just brings them to life, even something as simple as a 12t Ezrun.

I'm sure I read somewhere that a 28T will fit, but I could be wrong.

Will have to try find it again to confirm how big I can go.

It's for VTA class, so I'm limited to a 21.5T BL motor. (Which is only 1600kv)

All my problems would be solved if I could change to a faster motor. <_<

It seems a 29T pinion will fit, but only with the 0.4 gears.

25T is the largest I can go with the 0.6 set.

Seems like I'm in a bind.

Guess I can try a 25T, and if I can't keep up, buy a new chassis? <_<
