The aircraft was specifically built to race in the Unlimited class at the Reno Air Races.[1] Changes to the Unlimited class rules made the GP-5 no longer eligible for that class, so it was entered in the Sport class instead. Further rule changes excluded the GP-5 from competing in that class until the Super Sport class emerged. The Super Sport class was merged with the Sport class becoming, effectively, an Unlimited class for aircraft with engines less than 1000abbr=onNaNabbr=on displacement.
Sweet Dreams was entered in the Reno 2010 Sport class, but engine failure during practice runs resulted in the need to find a better engine/propeller/gearbox combination. Eventually the GP-5 competed in the 2012 Sport-Gold class at Reno finishing fourth.
On 8 September 2014, during a qualifying heat at the 2014 Reno Air Races, pilot Lee Behel was killed when Sweet Dreams crashed due to an inflight wing failure.[2] [3] [4]
