RTFM Aircraft ~ Home of the Tiny Cedar Flea

After a few weeks of intensive research, I have finally narrowed down the design candidates for RC (25% scale) testing.  They are:
The jean de la Farge “Pulga” variant:

Main features:

1. Main wings of equal span
2. Wings same chord (1m)
3. Tail wing also swivels (about 1/3 area of main wings)
4. Both wing swivel (front: 20 deg, rear: 40 deg, tail 60 deg)

Expected flight characteristics:

1. Very low stall
2. 5x speed range (stall/S&L flight)

Axel Darling did pioneering aerodynamic research into the so-called “Reverse Pou” and sometimes referred to as a Canard Pou.  So called because the smaller wing was in the front.  Axel calculated (and verified) that if the Eh and Ev (horisontal and vertical wing gaps) were identical, both wings would experience laminar flow.  In addition he writes: (Pou Renew ed 41)

“the smaller foreplane leaves lift bumps at about the vortex locations, which when the aeroplane yaws,
allows a much greater yaw/roll force and much stronger
dynamic lateral stability and much better and immediate pilotage in turns. This undoubtedly is the reason why the mad professor exclaimed that his backward Pou flew so much better than the reverse”

Main features:

1. Smaller wing in front, larger in rear
2. Vertical and horisontal wing gaps equal

Expected flight characteristics:

1. Superior handling, esp recovery from disturbances
2. Very low drag
3. Slower stall/landing

Keeping to the Axel formula, I’m going to try a low-wing Pou.  Why not?
