Schmleff,

I just now caught up with reading this thread. You are concerned that your observations on your design are being disregarded. It is an interesting design but the problem with your reporting is that the sweep angle is very low and you have only observational data regarding it.

The changes are small enough from a "normal" planform that I wouldn't expect to see any flight difference on a model sized airplane even with fairly good instrumentation. Even two identical airplanes with and without the forward sweep flown back to back with just visual observations won't show enough difference to notice.

I can get noticable performance increases in some of my airplanes by taking a cool drink before flying on a hot day. Ok exaggeration but I hope you see where I am coming from.

In my work as an engineer, back when I had to work, based on several years of working with a series of variable sweep wing airplanes I found that it is possible to measure in a wind tunnel the differences due to the angle you show in your model. However seeing those differences in a model airplane with all that that entails means that your observation data is going to be evaluated by people that have similar backgrounds to mine.

Don't get bent out of shape, get better data!
