Harold said; You cannot just call it a Motor glider as tempting as it might be.... there is a definition out there regarding what qualifies... the more stringent being "the maximum weight to wing span squared can not exceed 3.0 kg/m2 (0.62 lb./ft2)".
All details are outlined in Advisory Circular 21.17-2A. I checked on 21.17-2A. If you look at the introduction, it is an advisory for "certification" of gliders and motor gliders. I have no intention of certifying my aircraft. Patrick Driscoll Saint Paul, MN patric...@usfamily.net If you can read this, Thank a teacher If you are reading this in English, thank a veteran
