Florida Aero Services "After installing several Navajo ULTRAcooling Systems over the years, we at Florida Aero Services have found the quality of the products and ease of installation to be very good. We also found American Aviation’s support to be very professional and of the highest quality. Navajo owners with the American ULTRAcooling System installed on their aircraft have reported back to us with improvements ranging from ten to tweleve knots increased true airspeed. Keep up the good work!" Fred Ware, President Florida Aero Services, Lakeland, FL Back to Navajo Page
