I hope the project goes well.
The thing I noticed about the requests, was that apparantly the concept portion of a design became - using math to determine the design parameters.
Math is useful- of course- once the desired flight parameters desired are nailed down.
These, can be easily sorted out -in most cases - by researching past results for similar designs.

I am a great believer in experience and the direct hands on approach to all this stuff.
Those who know of Paul McCready-who designed the first workable man powered aircraft-may be interested in his approach to that design:
Apparantly - he was on a trip -driving a car full of shool kids -and the noise level was a real problem
he "shut out" the noise by thinking about how he could best approach the design for the Kramer Award.
The result was he decided the best approach was to work with materials which lent themself to easy and quick repair and modification.
A thoroughly practical approach.
Others labored over design tables an kept coming up with the same thing-a craft too heavy for the power available.
On a side note - I am doing a camera plane - which has to be light simple and a safe vehicle for carrying a 5 ounce video camera -A powered glider (I am using a RADIAN as the basis) converted to using two small wing mounted motors and inboard extended area flaps seem to be the best approach at the moment.
