What I would like to have/do differently (if I would be the Sonex CEO)

• modify fuse length/tail surfaces/CG in such a way that the airplane gains positive pitch stability
• offer a documentation pack which contains all calculations required for registration in EU-countries
• allow for engines of up to 250lbs (so that the Subaru or O200 or whatever automotive conversion could be used)
  • offer an FFWD kit for the Rotax 912(S)
• offer a silencer/noise reduction option to receive German 'blue angle' reward (which would allow flying on sundays and public holidays)
• offer full-swivel tailwheel option and hydraulic differential toe-breaks
• offer wing-fueltanks
• install a proper vertical instrument panel with space for all of the usual VFR instruments (including gyros)
• have a forward tilt/sliding canopy option so that passengers can enter from both sides, have real/contoured seats
• offer an emergency parachute rescue system (required for all EU ultralights)
• offer a horizontally split cowling
• offer one-piece fuse bulkheads (best with slightly rounded sidewalls to increase buckling resistgance)
• include step-by-step (Video, CD-R, printed or whatever) building instructions
• open a German/EU support/sales center
• offer a 'metric' version (all bolts, nuts metric)

list is ordered with topmost entry the most significant (in my very egozentric point of view)
