Kyosho Gears: 48 Pitch Or 0.6 Module?

[Snake Plissken]

As you may all know its very hard to tell the difference between a 48 pitch and 0.6 metric module gears. I'm trying to figure it once and for all: when did Kyosho change their spur gears to 48 pitch? I know that the Optima Mid had 0.6 module and so did the Lazer ZX, but does the Lazer ZX-R spur has the metric or imperial spur?

Good question! I think they sporadically used 48 pitch as "upgrades" for racing. As far as I know, they always used metric pitch gears. 0.8 and 32 pitch are nearly identical so they can be used interchangibly. This is what I remember most Kyosho's coming with as standard.

By the way, there are formulas out there for calculating the pitch/module if you really can't visually tell the difference between the two. I think all you need is the tooth count and gear diameter.

Kyosho changed to 48dp spurs with the Triumph 100 tooth spur, which was used in the Lazer ZX-R and later models, prior to the Triumph all Kyosho spurs were metric.

BTW if you raced a Kyosho in 4wd and an RC10 in 2wd it's amazing how quickly you learn how to tell the difference between the two sizes.

thanks for the info terry. Rich, do you remember where you saw the pitch calculation formula?

I found this on google.

Thanks Rich, I remembered seeing that page some time ago but couldn't for the life of me find it in google (wrong search words I guess).
