Overview
Here's my latest(and first truly successful) attempt at a basic, single pusher prop, 3CH slender delta type plane. This is also my first truly successful scratch built plane of my own design! Unlike previous(and potentially future) designs which employed elevons or a tail plane for AET, this slender delta plane is set up for RET. I did a little research, and found that other hobbyists have successfully built and flown RET deltas, some of which were a bit on the lower aspect side. Early on in my building career, I envisioned a few models that were sort of a delta/teardrop/almond shape with a round back. Some were wider, others more slender. I sort of shelved the idea for a while. I also had some pretty sketchy experiences with the Nutball, which to me is a cool concept, but I was never able to control it well. I also always found it too pitchy and the wind resistance is just non existent. I decided to "risk it for the biscuit", and combine my slender delta idea with the rear end of a Nutball, and got the lean teardrop shape I had envisioned early on, figuring that perhaps it would yield a plane somewhat similar in handling to a Nutball, but without the pitchiness and with much more wind resistance, but with a bit more sensitive roll axis and more delta-like handling, even as a RET configuration. The dihedrals came out long and wide without sacrificing much of the plane's aspect ratio, due to the rounded back. The fuselage is the basic high-mounted pusher nose nacelle I've been using lately, based off the Kolibri Flyer and it's straight slender delta prototype (thanks to @Dr. Looping Looie for all the help and inspiration!)
