Quote "Fail ! if you read the speedpassion site, the speedy you mention handles only from 9.5T on 2S (this is what is recomended). 8T with 3S ? what are you running ? ".
Thanks for the reply, checked site & downloaded a manual also. Found that the lowest turn motor for use with the GT2.1 prostock ESC on 3S is 9.5T, but using a motor less than 10.5T with stock software will damage the motor.
I have been using the 8.5T(sensored) motor on 3S with a 60A hobbywing non-sensored ESC, without problem so far (about 90 mins total runtime), so thought a 120A Sensored ESC would be a much better match, (but I dont know how the software works between the 2 of them).
The odd configuration is due to having no track(we use a marked out carpark), club or rules in my location, we just make do with what we have, I guess I was hoping that someone else has used the 8.5T with the prostock speedy with success, but knew it was a long shot!

If someone you know has a motor dyno, you can adjust the endbell timing to get the current draw as low as possible. now thw motor will be more efficient and the 3rd cell will give you the top end speed you want.
Another alternative would be to buy a 13.5 motor and run with that.

[QUOTE]The key to trying to run that configuration is NO additional timing. try the BLINKY mode and test temps of both the speedo and motor every minute or two to see how they are handling the additional voltage. Since you are running on a non-prepped parking lot, the traction won't be very high. That's a good thing for your test because there will be less loading on the drive system.

Thanks for the help. So, if the temps are low will the setup be OK? I have a Watt meter which I have used to test current draw on the 3S, 8.5T, 60A non-sensored setup, the current draw generally doesnt go above 59Amps, but I have seen it spike at 75A, that's why I decided to upgrade the ESC.
Also if I get a 13.5T motor, will I be able to run the GT2.1PS on 3S with boost & turbo safely (also checking temps regularly)?

You should be able to run boost with the 13.5 but a good rule of thumb is to start conservative and check temps frequently to find the right combination.
You're not likely to find much information regarding the use of 3s batteries since most people race and adhere to the rules in place for the most part.
I for one, will be doing some experimenting with 3s for a project car I am building. More about that later...

Dear Speedpassion usa support,
On July 2nd I wrote you an email reguarding overpayment on order 6791, I resent it that email on July 14th, I haven't heard anything back, so I'm asking here. my bank account shows a double payment, think maybe you can check into it and send a refund or maybe let me know if you got those emails

I guess maybe I should have asked a gearing question.

Hello
I'm looking at the following for my f104x1.
ANybody know if I need sensor cable & capacitor seperately or they r included?
Also any thought would be greatly appreciated.
