RE:Maybe DDC can show Workhouse how it's done !Shout out to PhantomSr on StockTwits A logistics firm that bought and tested an early version of Workhorse's (ticker: WKHS) drone, called HorseFly, says the product suffers from critical quality issues, including poor navigation software and substandard construction. The logistics company Unmanned Systems Operations Group, or USOG, said in its letter that it was unable to fly the drones as a result. In its letter, the private San Diego firm identified what it sees as roughly 25 issues with the HorseFly drone, including taped and glued-on components and corroding materials. The company said a communications antenna had come detached from the unmanned aerial vehicles. "HorseFly has a solid foundation to become a viable UAS [unmanned aircraft system] commercial platform," the letter reads. "Unfortunately, at this time with reliability and safety as our primary concern, USOG has grounded and suspended the use of the Workhorse UAS System."
