Winhern, motorgliders are one of the most under-rated machines going. You can have fast touring speeds with low fuel burn, great weight lifting capacity and fun all in one aircraft. The Grob I fly cruises at 90kts easily, burns about 12lts per hour and can lift two 90kg bods with almost enough fuel for about 5+ hours flying! I'm amazed there isn't more interest in them.
I think the gliding community / BGA are missing such an opportunity with motorgliders. Sadly, most clubs see them as some hallowed machine that sits around until some inner-circle instructor member decides to use it for field landing training or suchlike. There are legions of power pilots that would queue up to fly a motorglider from a friendly airfield, with great social scene and members environment etc.. I reckon stacks of potential students would do their PPL training on motorgliders as well given the chance.
