First Plane?
The very best plane for right now is none at all. Instead find your local club. Circulate and meet the folks, let it be known that you wish to buy equipment and get started. Virtually any club will get you an introductory flight(s). This is a huge advantage by connecting with folks you will be flying with first and you can be guided to appropriate airplanes and equipment that will make your initiation to this wonderful sport not only less expensive from inappropriate sidetracks but also far easier to learn.
