Contact Cammie Patch, or Craig McPherson (Texas). Both are very experienced instructors/dealers/AutoGyro brand experts. Either can guide you in a purchase or inspection. I have worked with Craig (Blue Skies PPC) and when I was having problems with the Rotax engine in my used Calidus, Cammie was very helpful with suggestions and offers of help. If you are considering a Magni brand gyro, then Dayton Dabbs at Lone Star Magni Gyro is your man. Hope that helps.
