sorry to hear that man, hobby shop is allergic to their customer when it comes to warranty issues, they will really pushed you away cause they have nothing to do with what breaks and fail. electronics is electronics period!! they can break anytime in any place. I had worse experience, I bought an RX8 from my local hobby shop about 5 months ago, I got home soldered everything, turned the power on, did all the settings, 10 mins after , smoke came out from esc, what i got ?? DEAD ESC. I am just saying they can fail anytime. to me it sounds like the esc is bad, I would send it in if still under warranty, TEKIN has a good customer service and quick turn around.goodluck.
