so i broutg a new wild thumper motor controller load code below on it and now te controller makes this noise whn i turn on te rc controller. also my ardiouno idle says its not syn. still it seems programs are uploading. basicly its the onl the rc code on the basic code provided . but as far as i know the sound indicades something is wrong because when i used my first vcontroller it wasnt making sound altho i did blow that one up after a while. any 1 can tell me why its making the sound i must have missed somthing ?
