XRAY - Model racing cars

I ve got a question...

I've this set and Im a new owner of SX6R and Im a little bit woried,because when i put trothle on maximum it sound low,but 1 sec later sound is way much lower

do you want short video?

Hi,

you need to set fullthrottle, neural and fullbrake before you use it the very first time. Did you do that? Also this forum could help you. It's from GM Racing:

You mean did I "calibrate" SX6R?
I did that
I pressed button "set" and then I put full trothle,fullbrake and neutral

Did you change the throttle/brake trim before or afterwards? That trim must be at 0 with 100% "EPA" in both directions. Maybe you could try to calibrate it again. If that's not working I would try a different motor (But sounds like your motor is new, too, right?) just to test. If then there's nothing better I would contact GM (also in English there, no problem). Ralf Helbing from GM sure will be able to help you out.

this motor is not new
but this motor is working

i can hear this sound when i ride car in home and he is "drifting"
maybe its because of that?
when i hold the car in my hands i dont hear that

Sorry but I don't understand what you are meaning with sound and drifting. Maybe you could post the video of which you were talking about?

i was yesterday outside and everything is working fine
