Mooney Owners, The STC Group LLC is ready to begin the STC effort for the M20 model. We have completed preliminary engineering studies on the M20. The STC Group LLC will be pursuing STC approval for all models of the M20, not just certain models or years. We will need get our hands on a few different years of aircraft to meet the above objective. If you are interested please feel free to contact me via email at paul.odum@thestcgroupllc.com. Do not reply to this post. Hav
