LOTS of PSR there Tophe, rather you than me.  :o
Any aircraft can be improved by fitting longer wings, and/or a longer fuselage

...and I'm not a closeted 'Take That' fan, I'm a REAL fan! :)

Regards
Kit

With paint, the Putty/Sanding/Repeat hardwork disappears... ;)
(or it should have disappeared if perfectly done) :-\

The SAM-SAM-13 is finished (according to my low standards)... :-\ ;)

My older brother, who offered me this SAM-13 kit, was surprised by my result and told me this will crash.
Smiling I explained him:
"si, ça vole, et même ça vole bien. Comme un hélicoptère standard (mono-rotor) : le rotor tournant dans un seul sens, ça crée un couple faisant tourner l'appareil en sens inverse, alors les constructeurs mettent dans la queue un rotor auxiliaire poussant asymétriquement pour compenser. De même un avion standard à hélice (mono-hélice) a tendance a basculer en sens inverse de son hélice, c'est hélas la normalité, et c'est souvent compensé par un braquage des volets d'aile pour créer une force inverse asymétriquement ; au lieu de ça, certains constructeurs choisissent un montage asymétrique annulant le problème par principe général. Le plus célèbre construit pour de vrai est le Blohm & Voss Bv-141, hélas nazi :
https://www.google.fr/search?q=blohm+%26+voss+bv+141&biw=1580&bih=757&source=lnms&tbm=isch&sa=X&ved=0ahUKEwji8qvEz87MAhUmAcAKHUTNBBwQ_AUIBigB
Pour ma maquette, la grande hélice propulsive produisant un couple basculeur (faisant plonger l'aile gauche et lever l'aile droite), cela est compensé par un rotor sur l'aile gauche pour la relever, et par un empennage baissant spécifiquement l'aile droite. C'est délirant mais plausible dans un bureau d'études, avant refus par le chef disant que ça gaspille de la puissance ou quoi..."

I try here to translate for you my words:
"yes, it flies and it even flies well. Like a standard helicopter (with a single rotor): the rotor turning in a single direction, that produces a torque making the aircraft turn opposite, and designers put in the tail an auxiliary rotor pushing asymmetrically to counteract. As well an airplane with a single propeller tends to rotate in the opposite direction of its propeller, this is alas normal, and this is often compensated by wing flaps angled to create an opposite force asymmetrically; instead of that, a few designers prefer an asymmetrical layout curing the problem by principle. The most famous, built for real, is the Blohm & Voss Bv-141, alas Nazi.
For my model, the big pusher propeller produces a torque (raising the starboard wing, the port wing tip falling down), which is compensated by a rotor on the port wing to raise it up and by a tailplane pushing down the starboard wing specifically. This is delirium maybe but it can be imagined in a design bureau before the boss refuses it saying this is a waste of power or else..."
