I have been attempting to get help from goodluckbuy regarding the gimbal I have not been able to get to pitch using the transmitter. After several emails I was sent to a link I was told is the firmware for the gimbal. The link brought me to a download page displaying what I believed was the firmware. In reality and unknowingly it was malware, one being something called Whitesmoke. This is apparently malware and in instances contains trojans and keystroke readers. I am running security programs now to remove the crap. So far my computer his only 11% scanned and it has detected 1, 100 harmful malware objects! I cannot say they are all from the download I was directed to but whitesmoke is 376 of the 1, 100 so far. I will open a case with Ebay and will dispute the purchase with my credit card company, they will never recive a penny of mine.
