During his time, Flashing Red crossed paths with harness racing's elite pacers Blacks A Fake, Be Good Johnny and SlipnSlide and his competitiveness made him "one in a million", Butt said.
"He was a terrific gutsy great staying horse," he said.
"I remember him sitting outside Blacks a Fake in the Victorian Cup and going down to him just by a head.
"He never missed a dogfight and never had an easy run, so horses like him, to still be giving when they are 10 years old, are one in a million."
Flashing Red contested most of the biggest feature races across Australasia including the Inter Dominion, Miracle Mile, Victoria Cup, AG Hunter Cup, New Zealand Cup, WA Pacing Cup, South Australian Cup, Queensland Pacing Championship, Australian Pacing Championship, Hobart Pacing Cup and Treuer Memorial.
Racing Queensland holds an annual race in honour of the Hall of Famer, in the first week of June, The Flashing Red Discretionary Handicap over 2647 metres. This year it was run at Group 3 level for the first time.
Flashing Red first announced himself as a star pacer in Tasmania as a two-year-old for Blomquist with a second in the Tasmanian Metro Stakes and third in the Tasmanian Golden Slipper.
He would go on to win 16 races of his 60 starts for Blomquist, including the Danbury Park Cup, the 2002 and 2003 Hobart Free For All and Devonport Cup.
It was as a rising six-year-old that he was sold and raced in Queensland.
Flashing Red was inducted into the Tasmanian Harness Racing Hall of Fame in 2014.
