64 or 48 Pitch and why
Im looking for a few answers. one alot of racers have said stop using the 48 pitch and go to 64 but I havent gotton a good reason why. What are the advantages to running a 64 over a 48? dose the 48 have advantages to the 64 and since I went from a Xray to a TC3 what is a good all around Spur/Pinion combo for VTA with a 21.5 and a SpeedPassion GT2.0 speedo.

Others have used 64dp with no problems and it allows for a finer range of gear ratio.

Agreed. There's no difference between 48 and 64. The only thing that 64 allows you to do is achieve a more precise/desireable gear ratio. For all applications, 48 will be fine.

I also found 64 pitch to be more reliable than 48 pitch now that we running brushless.
Myself and a few other guys in mod used to strip our 48 pitch but since going to 64 pitch no hassles.
i was told by a engineer buddy that its due to more teeth per cm when compared to each other which makes 64 pitch have more contacting surface area.
Bonus is smaller increment gearing changes making for finer tuning for racing.
also a lot easier to get a variety of pinions and spurs locally compared to 48 pitch.

Gear ratio is almost the same. Mechanically 64T gears have more contact of surface, Making it quieter than the 48T.
My opinion of subject.
Have fun!

48 pitch tends to be more popular with the outdoor crowd, with the thinking that the teeth are more resistant to damage from stones, etc. The indoor crowd tends to favor 64 pitch for the better gear mesh, quieter, finer resolution over gear ratios (which comes in handy for maintaining rollout when running foams), etc. Personally, I only want to have one set of pinions to share between my TC and 1/12 scale cars.

BTW: The finer pitch is slightly more effecient. This is why it runs more quiet. It's not enough to make you faster...

I honestly don't know why Jeff's Kyosho ate up spurs at such a rate. I've had the same 0.4module (close to 64p) 105T spur on my Tamiya for 2 seasons with no problems. Same aluminum 30T pinion has lasted just as long. I even acidentally melted one spot on my spur with a soldering iron and it still runs quiet as new.

Maybe im the only one that finds this weird, but why did you go to a TC3 from an Xray?

Overall I have always found 48 pitch to be more reliable overall with no loss in speedo and still efficent.
