I agree that the TS rotor being 14% larger would certainly be the main factor, but I've heard really good things about the Vulcan stators, so I wonder if it would be a winning combination to mix both products together to get the best of both worlds while still staying 100% Spec Legal

It sure would be nice to find which brand offers the best rotor, and then mix it with another brand that offers the best stator!

Need to be careful with this idea depending on how the tracks you race at view and follow rules. In the ROAR rules they do not allow for mixing and matching of parts. Technically you are not even supposed to use different endbells like a D3 endbell on a D3.5 ect.

If your tracks do not pay that close of attention, best of luck and let us know what you find out!!

The tracks in my area don't follow ROAR, they do ask drivers to follow spec limits... so we are limited to 21.5T spec... regardless if ROAR decides to ban a motor, etc. I seriously doubt anyone would have a problem swapping parts between two motors which contain 100% spec legal parts.

For the most part, we can tell that all our cars are in spec anyway, the performance is fairly consistent, however I have seen a car once that made me wonder if it had a 17.5T stator in it

Bill if KS = Kill Shot, I can answer that. the Kill Shot comes in a variety of rotor sizes and strengths 12.3mm to 12.5 mm (there are 13mm rotors too but those aren't ROAR approved for Spec racing) and RPM, broad power band, Torque. As I read the ROAR guideline only ROAR approved tuning rotors from the same OEM may be used in a motor. All of the KS rotors (except the 13mm) are ROAR approved for spec racing and are interchangeable with the D3. D3.5, Revtech, kill Shot and D4 motors. My RPM Kill Shot came with the 12.3mm broad band rotor. The Maxilla version comes with the 12.5mm torque rotor. Hope this helps t least for the Kill Shot motor

Just wondering. I have a brand new 21.5. How far round can the timing go out of the box? I have turned it as far as I feel possible and the pointer is between the last line and the 2nd to last line. If someone can confirm this is normal, it would be much appreciated.

thanks
Mike

Thats as far as it goes without internal grinding.

How hot do these motors run?

I'm running a 21.5 in blinky mode with an old xerun 2.0. Its getting just above 70 degrees celsius with no timing running 3.3FDR and no timing. That seems hot to me, but I am new to RC.

I'm also finding that it is a bit slow compared to the other cars in the field. Any advice?

your temp is fine. if you get close to the 90C temps thats way too hot. anything under 65.5 is very safe. but not much over that.

max your timing and gear down to a 3.5 to 3.7 in that range and it will come alive.

For small indoor track (55' straight, very tight infield), I'm running between 4.3 and 4.5 fdr. For a bigger indoor track (85' straight), I was running around 3.97 - 4.05 fdr.
Edit: this is for my 17.5 car in blinky. It gets to around 149F after 5 minutes at 4.3, but Onyx gets to 135F at 4.5fdr.

I also run a 21.5 in vta between 3.91 and 4.10fdr on the little track. Timing is almost maxed. It also gets to around 150F.

Hi all,

I have the Turnigy Trackstar 13.5T motor and the Turnigy TrackStar GenII One Cell 120A ESC, which will be going into my GT12 GT once it arrives.

Links for motor and esc here;
Motor;
https://www.hobbyking.com/hobbyking/...dProduct=39887
ESC;
https://www.hobbyking.com/hobbyking/...dProduct=57973

Could anyone give me a FDR for this motor and ESC please? Also has anyone fount a "sweet" spot or a good point for the motor timing for the 13.5T motor please?

Many thanks in advance.

Novak (Silver):12.3 x 25.3



I also found that the stator could be swapped out and was able to fit the Novak stator in my TrackStar just fine, which can provide a nice tuning option:



Has anyone been able to confirm if the Reedy Sonic rotors will fit the TrackStar motors?
The swapping is not legal and the Trackstar you are showing (Gray can) is not one of the ROAR approved versions. They are red. The rotor that was approved by ROAR in the Trackstar was 12.5mm (ROAR Max for spec).

Noob question, does anyone know how to increase the timing on the sensored 17.5 Trackstar motor? I've removed the end screws but cannot get it to budge. Don't want to pull it all apart, am I doing something wrong? Really want to increase the timing by about 10 degrees.
