stol concept wip Free 3D model

This model of a stol-lsa-airplane is work in progress, a lot of parts, like the interior are still missing. There are lot of details waiting to be done in the next few weeks. Like all of my models posted on grabcad, this concept was created entirely in my spare time. My idea needs to fits these requirements: -fits lsa requirements -max.599kg mtow -max.223 km/h -short take-off and landing capabilities (max.305-457m to take-off, if possible, even shorter) -electric propulsion -hydrogen fuelcell in combination with li-ion and/or capacitor for short-time energy boost during take-off and climb phases. -stable flight and slow-flight characteristics -low maintanance - -

Please feel free to come up with any new ideas regarding design or technical aspects.
