I'm not sure the CG's have moved as far forward as we might think, but if they have, it's due to reduced tail volume in the models with shorter booms. The short model thing is not universal or completely new. Richmond has typically flown short models in high ceiling environments. His VD equipped models for a few years were quite long (36"). I tried long models for a while too but couldn't find any perceptible advantage. Kagan's model uses a very large stab and is I think 33" long. Seeing it fly shows a clear demonstration that the setup works exceptionally well. I've stayed with lengths about the norm for the 1.2 g rules--31-32". I see no reason the change that. It really comes down to a wholistic approach. You establish a theory on what makes a good model based on experience and then you refine it to get better performance. Whatever theory you start with is going to have an influence on the optimized final design. There are a lot of different approaches to get maximum performance. Watching a comparison of Kang's launches against Brett's shows how stark the contrast really can be. The models look completely different in their flight patterns, but both put up spectacular flight times.
