My dear Smee - I've had an epiphany! I've heard (but not yet verified) that you can get a glider rating with less hours than an LSA. A glider rating does not require a medical (similar to LSA). A factory built LSA can be a glider (ready to fly S-LSA). Gilder pilots do not have as many restrictions as Sport pilots (though I don't yet know how they compare) A motorglider can tool around chasing thermals, or stay under power all its life, cruising cross country. There are only two types of LSA that can use retractable gear; an amphib - and a glider. Therefore: Design an LSA as a motorglider, and you can include retractable gear. Offer trainng for either Sport pilot or glider ticket. Motorgliders do not necessarily need stellar climb rates. Design with an engine more suited for cruise power than climb power (within reason). With retractable gear, you can attain the maximum level speed with much less power/fuel required. A lower cost engine is thus viable. Chase thermals or travel distances with power - freedom of choice! Be able to sell such a ready to fly (two seat) aircraft for under $40k. At max LSA weight, stall speed with a high AR wing could probably be met with a wing loading of 11-12 psf. To be able to fit in a sta ndard T-hangar (even though the wings will be removable) the span should be no more than 38-39'. An AR of 12 gives a span of 38', with a chord of 38", and a wing area of 120 sf (11 psf). Questions: What qualifies as a "motorglider"? Are there certain criteria that need to be met? Does this idea seem plausible?
