Jordan and the gang
It is nice for me to see many participants in this thread.
Admittedly we are not discussing a beginner's subject.
From the first posting, nothing is said about the type of plane. It only mentions the use of these fan motors under the wing(s). So all I could say is make it light and if it does not work (not enough thrust) the plane is not lost. More thrust can be achieved by switching to motor and propeller.
My understanding is that Jordan is working on his own model design and is not a beginner.
There are tricks in design to achieve a satisfactory performance of a new model in which the forces acting on the model can be compromised.
In straight and level cruise at partial power the forces have to balance in amplitude as well as in rotary momentum. Extra power has to exist to provide climbing.
Personally I like a balance such that adding power automatically result in a climb and reducing power automatically result in a descent. That is not essential particularly if the model is to be fully aerobatic and never flown in straigth and level.
I have to assume that Jordan is enjoying whatever he is doing or planning on and has the basic theory to guide him along.
I have seen some design guidance on the internet but I do not endorse the idea of "copy typical models known to fly nicely".
How well a model flies is very relative to who makes that judgment and his ability as a pilot.
I would dare say as well "the quality of the training received".
I think I am getting out of topic although I do not see the topic of this thread being well defined.
For sure two fans under the wing(s) will provide some thrust. We do not know how much thrust which led me to suggest to make the model as light as possible. Always a compromise to strength.
