Hi all.
For the 4th time I think I figured out what to build for Flite Fest West (and in general). With that April date looming larger, I buckled down and decided on a very conventional plane. This time I actually started building something
Fig 1. Twin Wonder Top View
I call it the Twin Wonder. It uses two 24g hextronik 1300kv motors, has 48" span, 7.5" chord wing using a Clark Y profile, and is intended to carry short range FPV gear, a GoPro, and a 2200mah 3s battery.

Fig 3. Wing (Main Section)
Fig 4. Airfoil Section Detail
Not particularly huge, but it has a more complex wing design than I'm used to. It uses formers to accurately make a Clark Y airfoil, and also needs a lot of accessibility to the wiring inside.
Fig 5. Landing Gear Design Sketch
There are also provisions for optional design objectives: a sprung, taildragger landing gear for soft-field takeoffs and LED strips for night flying, hopefully they will turn out okay.

Here's my most recent progress: Wing has no motor nacelles or ailerons yet, but the main section is complete and ready for having junk thrown at it. Fuselage core is complete, with battery shelf and reinforcements integrated into center section. Still needs, well, everything else a plane needs.
