Thank you again OVA!

Just curious about where the 2.05 comes from? Is that just for the TA05vII?

Zac_with_no_K

Just started to try and calculate some FDR's. (this set of results being 3.8 for 17.5)

At first I forgot to multiply by 2.05 and was getting results such as 96/25, 80/21, 76/20..

But once I remembered to start multiplying I got: 48/26, 45/24, 41/22 ...

I really don't know where to start from or if a larger spur gear is better than smaller.. Do any of these results sound like a good starting point?

I noticed when you lower 1 tooth on the pinion the FDR raises and when you gain a pinion tooth the FDR lowers. And opposite for spur gear teeth.

Does this mean lower FDR means faster and hotter temps?

2.05 internal gear came from the belt pulley 37T divide by center pulley 18T = 2.05

large spur gear are better than smaller..
think of the car steering wheel..the bigger steering wheel are easy to turn than the smaller steering wheel

the lower FDR will make the motor work harder...it like gear shift in the car started in second gear instead of first gear

what is the biggest 64p spur gear that will fit the ta05 ver 2 with out any modifications

I run 48P but the conversion is easy. The stock spur is roughly equivalent to a 70T 48P which would be about a 84T 64P spur.

I have run an 81T 48P but it sticks through the bottom of the chassis about 3mm. I haven't hit it on anything but I don't race outside. 81T 48P is equivalent to 108T 64P. I ordered a 73T 48P gear that I plan to switch to [I've gone back to the stock spur until it comes in] which is roughly a 97T in 64P.

So I'd say a 64P 108T spur is probably the largest you want to use for indoor racing on smooth surfaces but there is some risk since the spur sticks below the chassis.

If you have access to several 64P spurs around 96T to 98T, I suggest using the one fits without any part of the spur sticking below the chassis. If you are OK with the spur sticking below the chassis, then 108T fits. If you go much larger than 108T, it may rub on the aluminum mount or drag on the ground when the chassis rolls.

Hi thanks for the info, I have still not got my car its in transit, I am going to run it in 17.5 boosted class, so an fdr of 3.8-3.5, so if I were to use 64p gears what is the biggest spur, smallest pinion gear I would have to run, without any modifications, would a 100t 64p spur and a 58t pinion physically fit the car with out any modifications, if not then what are my options, thanks in advance for the advice

Does a different gear pitch change finding the tooth count at all? I'm not too sure but I think I have 48p installed at the moment..

I know 36t was too big for this car and someone online advised me of using 43t pinion with 72t spur. (Although it's incorrect for the v.II.. it was for the TA05 with internal gearing being 2.25)

Yes it makes a big difference, 43/72 is definitely 64p.

I don't think 100/58 fits, I run 82/44 for 17.5, that has room to go larger on the pinion.

Zac_with_no_K

Thank you, I guess I'll be switching to 64p then.

Another question..

Does anyone know if Xray or team associated on-road springs will fit the TRF shocks?

I know the xray springs have the same diameter of 1.5. I don't know if they're the same length or anything.

Just asking because I know my lhs has xray springs and not sure but most likely have AE springs and I would prefer to support them than making any online orders

I have the complete Associated tune springs set...will work on Tamita shock..I will let you know today..I think they are nip

Zac_with_no_K

Awesome, thank you!

I found the package..there are a few are missing in the package.I'm wondering who was in the cookir jar?
what color spring are you looking for?

is 82/44 in 64p or 48p thanks
