DAYTONA BEACH, Florida — Power Flow Systems reported recently that the Tuned Exhaust System it developed specifically for Cessna’s Cardinal 177RG, at the behest of the Cardinal Flyer’s Online (CFO) owner’s group, is now flying on about 20% of the fleet.
Initially, the company was reluctant to pursue the costly and time-consuming STC process for the RG airframe, officials noted. This was due to an internal analysis that indicated there were too few 177RGs in the GA fleet to constitute a viable market.
It was only after “considerable and persistent persuasion” from CFO’s principals that Power Flow re-considered and introduced its STC’d system for the 177RG in 2009, officials noted.
Since that time, more than 180 of the firm’s Tuned Exhaust Systems have been shipped and are now flying on 177RGs worldwide.
Chief among the documented performance improvements for the RG are a 10-15% improvement in the rate of climb and an increase of 2,000 to 5,000 feet in the service ceiling, allowing RG owners to cruise higher and faster, with maximum fuel efficiency.
