how to get the most out of 17.5
 

i lost some speed somewhere in 17.5 class..i dont know if its my motor.. my lipos..or my esc
i just started charging my 5000 40c's @ 10amp..(did i mess my lipos up by doing this??)
i been running the same 17.5 motor..(duo 2)..temps around 150 to 160
or i had a viper esc & it stop working..so i put in a 4year old GTB..could it be the esc..because with my viper in my car it was really fast & with the gtb its @ an ok speed.....just wanted to know what y'all thought:cry:
thanks

I'm guessing ESC......

thats what im thinking..but i wont know until i try another/better esc

Back to back testing would tell you for sure:nod: Are you coming out this weekend? I might be able to round up a Tekin RS for you to try.....

You can try changing the gtb throttle profiles, and make sure the motor is running at 30° timing, nothing less ....

i want to but in not 1oo% yet

Cool

well i did the different profiles..the deadband..min drive had it all set @ its most aggressive points....now im thinking it maybe my power trans cap...(dont know if that makes a difference in speed or not)....i did see smoke come from it back in the day..but the esc it still work so i thought nothing of it..(i wounder:eek:)

Have you recalibrated your radio to your speed control?

yes i have

It think the cap impacts braking.

You wonder right ! The capacitor protects the ESC. If the cap went poof in a cloud of smoke a long time ago, it is likely the ESC is open to being damaged ever since. Or you got lucky... but given your performance issues it is the first place I'd look.

thanks maybe ill buy a cap & see..(thats the cheapest way as of now):D
