Tamiya Type Rr, Rz, Tz.....differences?

[CarKing]

Can anyone help me out with the main differences between the Tamiya Type RR, RZ, and TZ motors? They are all listed as 23-turn motors, and all seem to have the same rpm range. So if they are so similar, why are there 3 different ones?!?!?!?!?!?

The RZ (red end bell & laydown brushes) is slightly faster in a straight line (higher RPM) than the BZ so is more suited to faster tracks.

The TZ (blue end bell & standup brushes) is the opposite, slower in a straight line but has the bonus of more torque so accelerates and pulls better so is more suited for tigher twisty tracks.

The BZ is for off-road use as it has some built-in dust shields and has similar characteristics to the TZ.

The RR I'm not too sure about, I think it's discontinued. I know the older Type-T, and Type-R motors wern't rebuildable where the newer BZ, TZ and RZ are

Thanks for the reply! The 3 motors are:

Item: 53696

Item: 53697

Item: 49260

I run the TZ and RZ in various buggies and trucks and the difference between them is not hugely noticeable. They're great motors and I swear by them. They provide the perfect balance between decent speed and battery run time in all the vehicles I use them in including my TXT-1 which has two RZ's in it. They look great too!

The RR has less than half the torque of the other two. Not very quick off the line, but probably longer run-times.

You can find the specs of most the tamiya motors here:

The Type RR is rebuildable, otherwise it is the same as the Type R.
