If it is slow and it had some dihedral you could eliminate aileron type inputs, just rudder and elevator and yaw it around a turn dihedral would keep it centered for straight and level.

But I would rater have a Sockmonkey’ish or Fritz’ish Style Fuselage on it, with thé engine up in front.
Although most of my time is with tractor engines on the wing they were well behind the cockpit and did not affect the view forward, considering the amount of crud they generated this is a good thing. I guess it is just looks that people like the engine on the front but considering mostly when you fly it is for the view do they really want the thing up in front? It is largely just a view obstruction.

Blane, I don’t agree regarding the prop position, having it up in front generates an additional airflow over the wing which generates lift. On the other hand a pusher pilot will fly his bird the same way, either engine on or off.

Sorry because I like you but BS.
Left-Turning Tendencies Explained: Why Your Plane Pulls Left During Takeoff
Have you ever felt like you're veering toward the left edge of the runway on takeoff?

As the American-built Dean Delta proved, delta pushers can exhibit complex pitch problems during take-off. For the purposes of this debate, wee will consider deltas to be merely short-span flying -wings.
First, the keep the propeller out of the mud, they need long main landing gear legs. ... at least half the diameter of the propeller.
Secondly, to prevent the airplane from tipping back on its tail - when parked with seats empty - those main wheels need to be a long way aft of the centre of gravity and centre of lift.
Thirdly, balance requires locating the propeller immediately aft of the trailing edge. Some deltas require extended drive shafts for balance. These extended drive shafts bring with them a whole series of vibration issues. This can create unstable airflow over inboard control surfaces when power is pulled to idle.
Fourthly, with the thrust line that far above the main wheels, it creates a pitch down moment with full power and a pitch up moment with zero power.
Since most take-off criteria require a large pitch-up moment - to lift the nose-wheel for take-off - but immediately after lift-off the pilot needs to relax pitch-up control inputs to avoid pitching up to ridiculously steep angles.
All those problems combined to wreck the Dean Delta during its first take-off.
That is why the majority of successful propeller-driven deltas: Delta Kitten, Dyke Delta, Facetmobile, Verhees Delta, etc. are tractors. The nose-mounted propeller is better for balance and its height can be fixed by a nosewheel that holds the wing at the precise angle needed for take-off. This pitch angle also happens to be the precise angle needed for landing. There is little point to flyng at a steeper angle of attack, because it just generates massive amount of induced drag which kills climb performance or increases sink rate. Rear landing gear legs can be short and light because they only need to prevent the trailing edge from dragging in the weeds.

Fauvel AV-36 and 361 plans project
This is not a traditional aircraft build, at least not yet. I have taken on the responsibility for the AV-36 after purchasing Falconair's rights to the design. After receiving the documentation It became apparent the the plans needed some significant updating. The 'master' plans showed their...

Between my personal situation and all of this Covid craziness it will still be a while before the plans are on the market again for the AV-36.
Lots of misinformation on the Wiki page for the AV-45. Completely different plane than the AV-36 - other than the general look.

Are you desiring to offer specialty parts in addition to the plans?
That was part of the original plan but given the cost of wood and the shipping involved - both ways - there just isn't any practical way to do the wood parts for a reasonable price. Metal parts? Maybe in the future if there is enough interest.
Debrayer isn't interested in doing plans for the Pelican. I think there is more of a market for it than there is for the AV-36. In our modern world a composite version of that seems to make a lot more sense than the wood AV-36. The have a slightly different mission but there is enough overlap to make me happy with the smaller plane.
You may consider the VP-3?

If you like more convicing about why place a tractor on a flying wing, go read this topic in this forum:

Recently posted to Twitter, by someone who visited the Monino Air Museum near Moscow. Said to be called the "Discoplan." Some of you might find it familiar-looking.
