Calculating wing weight
Does anybody know any equations or references for calculating the weight of the wing of a small rc aircraft. I have found some equations from aircraft structures books but these are related to large transport or military aircraft.
Just to give some background information. The aircraft will have a maximum weight of 1.5kg and the wing will be constructed from foam (most likely EPP). Although the aircraft will use a standard wing configuration the exact details such as airfoil geometry, taper ratio, sweep angle etc are unknown at this stage. The design will be manufactured and built but the weight of all components is necessary (before manufacturing) to determine and optimise the cg location.
Any help would be appreciated for finding the weight of the wing (not including spars) and its local cg location.
Many thanks

RE: Calculating wing weight
Welcome to the RCU forums, desert_orchid10!
Your problem is too vague to have many responses at this point of your project.
There are two parameters that you need to estimate first: the volume of the irregular shape that the wing is, and the mean density of the materials to use.
There are several ways to estimate or run a first rough calculation, once you have some initial estimations.
