It would of course have to be built ridiculously light.


Knowing you Q .... you could do exactly that !! 

Me ? I'm nowhere near as good at it as you - so I will be using pusher props ..... 

But I think you are right - but I would still reduce the main body height I think .. with small increase in wing area .... 

The Tail function ... that is a concern as the 'elevator' is so high up away from the props ... and will need decent airflow to work.

Now question is ... size and what power setup to use ... 

Using the typical 2826 2200 Turnigy motors (twin) in my view would be too much ... 

Pity the Floaterjet motors are no longer available ... 

Trawl through Banggood site I suppose for a pair of opposing motors in the high kv but slightly smaller size ... ie 2812 - 2818 and 2400+ kv ... to run 4" props ?

Racing quad motors with 'handed' props are a good source of cheap, high(ish) kV types and most are good for 4s.
I used a pair on my Airbus A350.

4 blade 3x3.5 props inside each nacelle all driven by just a single 40c 1000mAh 4s.

Does an elevator have to be in the prop slip stream?
It isn't on most EDFs and they manage.
Surely its all a matter of sufficient elevator effective area and CofG position.

Well we know that many elevators are not in props airstream ... but then its a matter of airspeed and flow over it.

My concern is that big body causing bad airflow and the elevator being relatively small and high. Possibly being high is good considering that bulbous body ... and make elevator a bit bigger ??
