About a year or two ago, Sentry sent me a PM on RcGroups asking if I would join the group here and add a few words on a project I had done and shown there. Well, its been a long time leading up to this; I'd like to show my VTOL design, which I've been working on over a year.
The "Orange Hawk" VTOL Design
Wing Span: 1000mm Area: 21.5+2.6 dm^2 (Elevons)
Quarter-Chord Sweep: 30.0deg
Airfoil: MH45 with Root: +2.0deg Tip: -0.5deg
Material: 21.0kg/m^3 EPP
Equiv. Rotor Diameter: 500mm
Flight Controller Based on MultiWii 2.1
All-Up Weight: 1.2 kg, Theoretical Maximum: 1.5 kg
Designed Fall 2012
It tilts the front two motors to differentially to control the reaction torque / yaw, and tilts both together for entering and exiting forward flight. The aircraft is designed to receive modules or mechanism attachments with a 25mm-pitch square grid of 3mm holes, allowing for future expansions, such as Taco-Dropping Mechanisms, LIDAR, etc. The picture below shows the vehicle with a potential computer vision target for truly autonomous missions, though I guess the folks here are more interested in FPV. The introduction video was done semi-FPV, with me mostly flying LOS and some glances at my display.

I'll mirror the main venues where I've been rolling out the details:
