I'm going to start racing at a track 200' x 100' asphalt. Rubber tire Sedan.

7.5T Tekin. What is a good starting point for FDR, motor timing and boost timing?

The esc is set in dual mode per your email settings, so I'll reset to sensored only and see if that solves the issue. And the motor is fine I've used it with a gtb with no issues.
That thing about the lights in Randy'/s post was directed to someone else from a page ago who was having the 1,2, 6 and 7 lights come on with a brushed stock motor...

The part of his post that was directed to you mentioned to use the sensor check to make sure that your sensors and cable are okay... have you done that? switching to sensor mode will not do you any good if there's something worng with the sensors or cable.

With your car and transmitter on, leave the throttle in neutral and rotate the spur by hand. You should see the last three leds on the RS going on and off in sequence. They're not going to be full bright, so look close. That's the RS telling you it's seeing the three sensors... IF you don't see those last three LED's alternating on and off with rotation of the motor, you have a bad sensor or bad/disconnected cable.

Thanks Trips!

SRW, I'd start your setup with Sensored only mode, 0 motor timing and 15 on the boost to start out. That track sounds big and the 7.5 will need some revs. I'm guessing an FDR around 6.5 to 7.0ish. Without seeing the layout it's hard to say really.

Check motor temps often, compare speeds,etc.

You decide on a car yet? Make sure you check the car out on r/c carfax first

Thanks Randy for the info. The infield is technical.

hi guys,

i upgraded my esc to 194 and installed my car, and make the settings how randy suggested in the forum and it works perfect no problem....
but my friend has the same esc and make absolutely same everything, but motor runs reverse.

we tried everything with and without sensor nothing helps.
the connection between esc and motor is as it supposed to be a to a , b to b , c to c.
when we reverse the a and c,
1- if the sensor is not plugged, motor hang ups, reverses and then starts working normal
2- if the sensor is plugged everything becomes overheated, it draws so much from battery even the other fans slows down. the cables becomes burning heated.

he tried to install version 180 back, it didn't help.
what you suggest.

edit: also tried with 3 different motors, nothing changes.

2wdrive, of course we tried that, we are talking about bl-fw mode, what is it to do with reverse function????
if you set it wrong , when you apply the brake it spin... but our problem is it spins on the wrong side....

"i upgraded my esc to 194 and installed my car, and make the settings how randy suggested in the forum and it works perfect no problem....

well i read that your motor was running in reverse? Does it do that only in BL-fw? The other settings the motor runs fine?

I must admit that i only read the third message up and there was no mentioning that you only had problems in bl-fw or brake function.

Anyway.....sometimes a problem can be something very simple.... maybe this time it is not the case hehe.

Yes the RS Pro can run a delta wound motor.

From the sounds of it you've updated the esc. You MUST have a to a, b to b, and c to c . If it runs backwards my guess is that it's not a Tekin motor and that you've somehow managed to spin around the endbell so far that you're firing on the wrong phase. I've seen this with a Duo and another brand of motor. There's no "stop" to prevent this. Since it does it with "other" motors and yours works correctly use your motor to test it.

After you upgrade the software you MUST recalibrate the esc to the radio again. Make sure that you max out your epa's when you do this also. Make sure there is no abs or traction control function turned on.

What kind of car is this in?

I also reset the speedo after updating to be sure that it's ok.
After resetting i recalibrate my transmitter to the speedo. after that i program my speedo again with the right settings.

A club member forgot after updating to recalibrate his speedo.
He didn't hath a lot of power but after resetting adn recalibrating the speedo it worked great.

I tested full timing on the motor and full boost.
didn't drive with the car but just hold it up in the air and puled the throttle.
The Tekin 10,5T motor maked so manny rpm's that my tire riped of.
incredible power.
Tomorrow i test my tekin motor geared very light with 24 on the motor and 6 on the boost.
from there i start gearing it heavier. hope to get some more top speed.

After that i try to ad some boost.
not much but a litle bit like up to 10 boost in total.
and chek the temp.
