Subject: [RCSE] 2M Re-Visited
As a diversion from the LSF angst, I'd like to briefly resurrect an old
thread. Shortly after NATS there was a flurry of dialog regarding 2M design.
My comments, in general, suggested there was still some room to upgrade 2M
designs, look more closely at the Drela airfoils, optimize planforms at the
wing loadings we could achieve, etc. etc. So for the last 6-8 weeks that's
been a fun project. The result is a poly, aptly named the Kahuna 1.8 (2M
doesn't quite fit in the bed of my truck so we opted for 72 span). Although
a poly, it's intended to be a validation platform for trying a few things
out. Basically a V-tail, pod and boom, Drela section, optimized planform for
the wing loading and still winchable at an AUW of 19.5oz. The structures are
basically similar to DLG but without the need for a sub-rudder. Other than
that (and swapping out the airfoils), it's more or less a discus on steroids
