So as to avoid a long discussion about this in the forum I put this in a PM. Tango gyros have the Yamaha engine option. The Tango 2 may be what you need. Once built, with a LODA, you can instruct. Dayton Dabbs at Lone Star Magni Gyros is a gyro DPE, and he has been through the LODA process many times with the FAA. The Sparrow Hawk and the RAF both use the Subaru engine and are relatively cheap, but I am told the RAF is much more stable with the later optional horizontal stabilizer/tail found on the Sparrow Hawk. As far as I can tell, a Magni or AutoGyro will run $70K or more lightly used, but a Tango 2 will be $50Kish new, and an RAF or Sparrow Hawk 2 will be in the $25-30K range used. Experienced instructors all have ideas about stability and reliability so talk to some. Good luck. I fly an AutoGyro Calidus with the 912 out of Boerne TX near San Antonio. Ray
