Don´t forget that 15K EUR is for KIT (and depends what stage of KIT is in this price). Plus... to have a self launch you need to add price for propulsion system. However I agree that is good price for composite plane with L/D 1:30 and low EW-in my opinion=the best of the bests ! (for not rich pilots...)
f.e. L/D=30 / 15 kEUR +some homebuild work.
=my concept of not pricy propulsor= DC PM motor ( LEM200) +simple discreteneed to add price for propulsion system.
Well... I am a bit conservative+very low Cd fuselage (Goldschmid aerodynamic) + low Cd wing (BKB1-A type, NACA8-H-12) with AoA control ("FREEWING"=super big Cl at AoA> 30 deg.) =super energyeconomic flying device...
thanks !"V" tail has lower drag than classic "T" tail.
Well... I am a bit conservative
Nothing against your design.
"V" tail has lower drag than classic "T" tail.
Just... when I was flying with RC models I noticed difficulties to recover spin with "V" tail models. What I want to say is that when you will start test flying pls. focuse on non standard situations like stalls, stalls during turns, spin recovery and flutter resistance. This is even more important when you use unusual aerodynamic solutions (free wing).
When I fly with new airplane I am glad to feel performance, but I am more glad if flight characteristics are friendly. In other words - I try to imagine situation when airplane is flown by non experienced pilot making mistakes.
Airplane you design has "V" tail?
