Last winter we designed a new 82 inches Rafale and we are planning the first flight in 2 weeks. We have a good idea where the c.g. will be but would like to compare it to either BV or AD large Rafale. To be able to compare it we would need the chord length of the root rib and the distance of the cg from the leading edge. The ratio of these two measure will give us a good idea of the position of the cg on our wings.

The added picture is 2 months old. We are near completion now.

Your help will bee greatly appreciate.
