Default Metric Pinions for Tamiya Tanks

All,

I am looking for a 12T metric pinion for some motors I'd like to purchase. Any direction on where I can find this?

What is the inside diameter you need?

2.3mm. But Daryl said, the reason my other motors were making a noise was due to the the pinions not being metric.

what is the pitch you need - my guess is either 0.5M or 0.6M. There is something called "metric 48" which is actually 0.6M, but it is a misnomer because US 48p is actually very close to 0.5M. These are the formulas you need if you don't know how to calculate pitch:

Metric: Actual diameter of gear in mm's/(number of teeth+2) = pitch

SAE (US): number of teeth/pitch diameter in inches = pitch
  [where pitch diameter is the diameter of the gear half way up the tooth (as opposed to the actual diameter.) So its a little smaller than the actual diameter by the hight of a tooth.]

One you know the pitch, google the number of teeth, pitch and inside diameter - for example 12t 0.6M 2.3mm

If they look about .5m or 48 pitch, they're probably .6m.
.6 mod is what many of Tamiya's RC cars and trucks use.

How is the noise level using this gear? Did you have to alter the motor mounts much?

I have either the 11 or 12 tooth IMPACT pinion gears that I need to use and would like to know of it's performance.


Thanks!

Panther F,
Impact gearboxes are normally very loud, so it would be hard to know the difference. Impact has adjustment designed into their gearboxes and they worked well, especially when used with the DDG (Drop Down Gear) setup, by choosing a Hop-Up gear setyou can pick your desired gear ratio. Check out the chart on the mitosal site for the different gear setups they offer.I never tried other gears on my motors except the 12 tooth pinions. The Impact gearboxes drop right in, at least mine did. I have read some people having to make some adjustments to get all the mounting points to line up but I did not have the problem.
dlobmwm3,
I see Bob at ETO has them in stock you can save some money on the freight if you get them there.
