hey guys , i am studying aerospace engineering . We have a project to make our own RC aircraft , all of the materials are given from our teacher, all we need to do is design the structure of the aircraft / the whole body of the aircraft. We have 2 projects , first we gonna be making an aircraft from a foam and then by 3d printing ( materials haven't decided yet for 3d printing). we will be given 3 servos, a motor and propeller and landing gear , the motor only capable of lifting aircraft with the weight of 100 grams on average ( based on last semester's data). So actually the teacher been using the same motor for all the previous classes, which means that we have to design an aircraft that weight less than 100 grams. The teacher told us if we make an unconventional aircraft ( delta wing , swept back,etc), we will have more marks. so my question is , what should be my first step ? deciding which airfoil i will use? ( we can copy the airfoil's coordinate from internet and put it into the catia or other software). I need advice really bad thanks .
