Did you have a chance to test it?

Hobbyking now has 2 17.5 motors, but at different Kv ratings. I am curious to know how they perform at 35$!

I've been testing the turnigy silver trackstar 17.5T motor in my tamiya RM-01 and the motor is great, runs cool and has lots of power.
I can recommend this motor to everyone who wants to keep an eye on their budget.

The Trackstar 17.5 2270KV motor is ROAR approved. My ESC/Motor combo just arrived and has the ROAR approved stamp on it.

There are torque(very low kv) motors, and there are Rpm(high kv) motors... Low kv motor gearing should be around 3.0 to 3.2 fdr , and high kv motors are around 4.0 to 4.2fdr... Low kv motors like low timing(30 degrees), high kv motors like high timing(55+ degrees).... Once you identify the kind of motor you have, gear accordingly or else poof....

You need to stop giving out advice. Poor newbies who listen to you will blow their motors. At least the regulars on the forum know to ignore your "advice."

I would never gear lower than 3.5 and this is outdoors with quite a long strait.
The usual gearing for 17.5 TC is between 4.1 and 3.8.
The timing and gearing need to be set to suit the track layout.
I.E. shorter gearing/ lower timing for tight tracks and the opposite for large flowing tracks. The settings depending on your driving style too.
Therefore start with the gearing I mentioned and about 40* timing and adjust from there.
I hope I could help.

Look for the Novak Ballistic, Reedy Sonic, LRP, or Speedpassion. They are all excellent motors, and you can never go wronge with a name brand motor.

Have you heard of Trackstar motors before? They look really decent for the price, but I don't know the quality yet because I do not yet have one (has anyone got one? I'd be interested to know what they are like).

I plan to put one in my Tamiya TT-02b (metal gears fitted)

I have the Trackstar 17.5 2270Kv motor and it runs great. The timimg for this motor was max out at 30* on the skyrc motor analyzer with a Kv reading of 2263. 6 minutes of running and the temp was only 112*F.

Q1) Do you reckon I will need a fan and/or heatsink on the motor?
Q2) Will I need an new 'propeller shaft + joints' (the stick thing that goes down the middle) as my current ones are the standard plastic ones?

Sorry if its too many questions XD

I would suggest fitting a fan even on the TT02B. With the TT02B you cannot get to a really low FDR which would give the motor much to worry about, (I think it's 9.5ish) but the fan would work well as a precautionary measure.

Fans are cheap, and you can easily fit one as the TT02B has a plastic fan mount on the motor cover, so remove the scoop and fit a fan on there.

As to the drive train, it will be ok with the plastic, but the aluminium drive shaft and cups will just be less prone to twist. I would say initially you would be better off to buy the tamiya Aluminium Motor mount (Tamiya 54558). That will act as a heatsink and keep the motor aligned with the extra torque that the brushless motor will provide.

The TT02B is a great car to have fun with, have fun with it
