On the NSRCA site, I was looking at the gallery. Many seem to be powered by 4 strokes and look quitelarge for avg weights of 10lbs. Are the 4s for the steady pulling power.. and light weights due to composite construction? I like the old school looks of some.
True, the so-called wide body 2 meter designs may look too big to get pulled around by a mere 1.4 to 1.7 ci engine, but they are mostly comprised of air surrounded by a thin, light composite structure of some type. Nothing too fancy is needed for the most part. You can make a very light composite fuselage that is mostly a light balsa / fiberglass composite, with a small bit of carbon fiber and plywood for high stress and hard point areas. Good old balsa sheeted foam wings & tail are still a great way to make a light airplane, but you also find some nicely done composite wings. Suggest you check into Wistmodels and ZNLine. ZNLine has a new American importer now, Chris Moon at

These days electric power is quite popular and growing fast, but 4C's like the YS 170 DZ and the new CDI version are still popular. Even a good 2C like an OS 140RX can pull a light 2M wide body like a Prestige (Wistmodel) with authority. From what I hear the ZNLine Xigris should come in very light as well. I have one on order.
