A few more explanations on this aircraft and its construction / weight:
It is built with the aim to fly outdoors with a 800w setup. For the casual flight, but also for 3D.
If I only was going to fly indoors, it was obviously built differently
And I just wanted an indication - will the speed be 10 or 20mph.
easily 20 mph and less if you have power enough to hold a higher angle of attack
Slow flight is not all about stall speed - the plane will still fly in a stalled attitude IF you have thrust loading high enough to keep it up
yesterday when we were doing indoor flight (Friday meeting is in a very large gym). We eyeball measured forward speeds -Our group includes Physics prof, Structural engineer Professional model designer etc., and we all agreed that the little VAPOR could fly , slightly vectored at aprox 1 meter per second.
level flight brought the speed up to closer to 4-5 m per second. ( lift /drag change makes big difference).
My own, old Seniorita which weighed 3.5 lbs -800 sq in., would fly outdoors in the under 20 mph speed range
Just some comparitive info-
