Cascade Aircraft Conversions, Just recieved STC for a Barrier Filter Modification for the Hiller/Soloy and the Bell 47/Soloy.
We helped with the Data acquisition for the mod, and saw a 35 Deg. lower TOT during Data collection with the New filter vs. the old Centri-Sep Particle Separator. A Huge improvement in performance, especially at hot and high alt. conditions. Check it out! http://www.cascadeflying.com
