Poll: What pinion/spur you running on TC3/TC4?
 
I'm interested in compiling some simple real world data on exactly what pinion and spur setups are working with exactly what motors. I think this information is useful to compile in one thread, for future reference by TC3 and TC4 owners.

TC3 or TC4 owners, please post:

Car: eg. TC4
Motor: eg. stock 15t
Pinion Gear: eg. 24t
Spur Gear: eg. 61
Any Other Information: eg. overheats after two battery packs.


Thanks! James

Here are the three setups I have used at one time or another.

TC4, stock except for metal outrunners and CVDs.
spur 78t
pinion 19t
Neo 3-star (6.5r) motor.
Sphere Competition ESC. 2-cell LiPo.
Runs very hot, heatsink and fan recommended.

TC4, stock except for metal outrunners and CVDs.
spur 78t
pinion 16t
Neo 4-star (5.5r) motor.
Sphere Competition ESC. 2-cell LiPo.
Runs hot, heatsink and fan recommended. 44mph top speed.

TC4, stock except for metal outrunners and CVDs.
spur 78t
pinion 21t or 23t
Mamba Max 5700kV motor.
Mamba Max ESC. 3-cell LiPo.
Can run hot, heatsink and fan recommended. 49 or 54mph top speed (theoretical top speed is 2.84mph per pinion gear tooth, actual is around 2.5mph).

Here are some updates from my TC3 and TC4:

Team TC4:
Pinion: 24t
Spur: 72t
Motor: 19t Reedy Quad Mag
Motor would overheat when I ran it in a really humid climate, but in a non humid climate it's nice and cool. This is doing drifting.


RTR TC3:
Pinion: 28t
Spur: 72t
Motor: Silver can 27t
This setup would also overheat in humidity but not here on the west coast, even on a hot day and after an hour of constant drifting.

ft tc4 27t 72spur sock,19t and mod good for all round speed and power.

TC4
Novak 6.5R
Stock spur size
20 T Pinion

The motor and ESC never overheat. I do have a fan on the ESC and a heat-sink on the motor. I would say 50-55 mph top speed.

Going to upgrade to the Novak 3.5 when it comes out.

RTR TC4
Novak 5.5R
Pinion: 22t
Spur: 72t

I hit about 50mph. I think I figured with a 31t spur I could hit about 70mph, but I don't have an airstrip handy to try it out.

it is very helpful to go to 64 pitch gears on touring car, i run on mine 32 tooth pinion and a 107 tooth spur with 6.5 novak. This thing is insane.

explane how thats going to be helpfull.all its going to do is wear out quicker becouse of dust and sand.the only advantage with it is more gear options lol.and 48 pitch already has insane amount of gear tuning options.also explane how it would be faster.

TC3
Motor: Speed Gems 2 10t
Pinion: 19
Spur: 72t

Just popped this combo in to test it, but the motor and Tekin esc get too hot after 10 minutes of high speed runs.

Basically using a finer pitch can actually make the gears last longer and have less 'slop'. If, at 48 pitch, at any time 3 teeth are touching between the gears; at 64 pitch 4 teeth will be touching. Plastic will typically flex until some force / pressure is reached, after which it will permanently deform or break.

yea 4 teeth are touching but they are smaller.and if any amount of sand gets in them they are ruind.unless you race on carpet or indoor tracks with no dust they are useless.
