The funnel is based on Vien Dong 5. VTC Sky on 28 September 2007 shows an alternative with a narrow black top, straight upper and lower edges to the oval, and a darker red closer to the website flag logo; Rosanoski finds no apparent reason for these differences on similarly sized funnels. The flag logo is horizontally red over blue with an overall yellow V whose dexter arm is thicker. António Martins-Tuválkin comments that its overall scheme is based on the Vietcong flag.
