Yup these motors are legit. If you are a more budget conscious racer these are for you. I have been really liking the one in my USGT. Set fast lap last Sunday (I broke out tho).

How did they run stock? I plan on running a 21.5 blinky foam and a 17.5 vta class at my local track.

I've run 350 packs through my 17.5 and it is still working well. my 21.5 has been working well, too, although I have been finding that I need to gear it quite short due to it having a higher KV than other 21.5's. I run a 4.03 FDR and still get up to a higher top speed than most, but is soft out of the hole. I feel that going to a smaller pinion would help.

Has anyone here run a wind other than 17.5 and 21.5? I'm thinking of picking up a 8.5 or 9.5 for TC mod.

Default 13.5 and 21.5 settings

Anyone successful finding a good motor timing and rollout for 13.5 blinky 12th scale?

Or motor timing and FDR for 21.5 blinky F1 rubber tires?

Thanks,

Ivan

Hi, I've got a Turnigy Trackstar 13.5t 3040kv in my Tamiya M05.
I'd like a bit more speed, but I can't gear up since I'm already using the 20t pinion that's the max for this car.

This motor has variable timing (static), and my Esc has timing as well (That's dynamic I assume ?).

Currently the motor is set at it's default timing, and I've set the Esc timing to "High".
Would I gain speed and/or torque by increasing the static motor timing as well ?
How do I know how to balance motor timing vs esc timing to get the most rpm / torque ? (or is it a balance between rpm and torque ?)

Is this correct ?
Looking at the endbell the + is counter-clockwise, - is clockwise.

So is rotating towards the + "more timing" or "less timing" ?

Well I ran my 21.5T trackstar in a race a couple days ago. I had the timing on the back of the motor maxed out. I was getting smoked in the straights. I was running 88/48 gears in my TC4 which comes out to about 4.58 FDR. After the races the motor was barely warm to the touch. I was going to swap to an 80/48 4.17 FDR but the guys I was racing with kept telling me I was going to burn up my motor if I did that. Any truth in this or would I just need to run a fan on the motor? I was taking to one of the faster guys after the race and he said he always runs between 4.1 and 3.8 FDR in his xray car depending on the track. I'm wondering if the other guys I was running with didn't know that the TC4 has a 2.5 internal ratio as they all run xray cars.

you should be alright...put a fan on it..& just check the temp after 3-4mins

really? that high of a fdr? no wonder your getting smoked. both of my ts 21.5 motors i ran a 3.6 to a 3.7 fdr depending on track size. I always run a fan and i never got over 130 degrees. only one track it got hot at as it was almost 100 degrees that day and it was a small track and i was over geard. totally my fault. but try around a 3.7 with a fan. max timing. i have put these on a g force motor checker and the timing is about 35 degrees. so its not really much timing. gear up bro and go for it.

How long is the straight? You should start around 4.0 fdr on tiny tracks, and move towards 3.5 fdr on bigger tracks.

This is just a ball park guess but I am guessing it's about 60-75ft

at that lenght straight i would start at a 3.8 fdr and go from there. if it gets too hot, above 130 the go back towards 4.0. if its still cool then gear up more towards 3.6. remember these love fans and they have alot of torque since they are low timing motors. i could keep mine under 130 even on 90 degree days. good luck and report back on performance.

What kind of fan do you guys recommend? A clip on heatsync one or something else? I have the fan scoop kit for the TC4 that pulls air from under the car through some large holes in the chassis. Should I run that or something else? It worries me because it pulls air from under the car and that makes me think it will cause lift in the corner that its under
