A suggestion….from a non-engineer.
Make the bottom vert. stabilizer srong enough so its wheel can absorb a heavy tail down landing without damage. (Perhaps use it’s strut as the leading edge).

With such a short wheelbase and overall length, I have a feeling it would be used a great deal.

As I recall, the BD-5s were very unstable in pitch and susceptible to PIOs…this design looks like it might be as well.

Boyle,

You have very good points. The strut and leading edge will be used as you said. In Dh Airco they had neat usage of the leading edge as well ( WW I design ).

This design actually came as a by product of much slicker pusher and I just wondered if this could be plausible as AIR SCOOTER..if we think PA-28 as a familycar with 4 seats ?

I am at time being copying a set of Lear Fan 2100 description from FLIGHT magazine 1981 Christmas edition. I have also discussed some aspects of it with Mr.Penney who test flew it ( in a chat ). Several questions remain open to me of this kinda layout. I see it is pretty economical…about 3.5-4 liters / 100 km / person on board…better than in a so called smart jets that consume 6l / 100 Km / person.

Dh-89 Dragon Rapide is really good too in mileage !!! : )

CG may be hard to manage in a really small plane ( due to pilot who might weigh from 120 – 250 lbs ). That may be a cause of PIO too in planes this small…also in Gnat jet etc.
