I've been several months under the radar, being pretty elusive. My apologies to all who are or have been hoping for more information. I noticed this morning that there have been a consistent number of views of my goofy Introduction video, and so I'm obligated to fulfill the steady interest.

I presented the Orange Hawk at the AIAA Region VI Student Conference, held in Salt Lake City, March 28-30, 2013. As an undergraduate, I won 1st Place, and was spoken of highly by the attending AIAA special guest, Dr. Sandra Magnus. As I've won the regional conference, I will be one of a dozen or so finalists to present in the AIAA SciTech 2014 conference being held in Maryland this January, less than 25 days from this writing. ("Dozen" as in a handful of other undergraduates presenting in the student competition, the SciTech Conference proper will be huge with hundreds of presenters.)

I've probably placed about 2 hours of flight on the Orange Hawk prototype since the conference, of which about 20 minutes has been sustained forward flight. The majority of that flight time was accumulated in May and late August and the first week of September. I took an internship with Raytheon in Tucson AZ for June to August, and only flew the Orange Hawk twice during that time, due to the lack of accessible fields (it is nothing but cactus there) and little time. One flight is documented in this Vimeo upload:

Attached here are the design documents I used for laser cutting and construction jigging / rigging of the Orange Hawk VTOL.

The "Orange Hawk" used my modification of the MultiWii 2.1 opensource flight controller software and hardware architecture. I've polished the code and am attaching it here. The following pages will link to this blog post:
Introduction to the Orange Hawk Project (0 min 0 sec)

The attached ZIP file has the following text included with it:

Version 1.0 Released 19 March 2013

This Codebase is for the Orange Hawk VTOL Hybrid, released March 2013.
It compiles in Arduino 1.0 and Processing 1.5.1, using MultiWii 2.1 as the base code.
The Processing library controlP5-0.7.5 is used in the MultiWiiConf utility.

In August 2011, the author, Steve, decided to pursue a life-long goal of making a VTOL dream machine.
The goal was to create an aircraft capable of hovering and VTOL operations, but with the efficiency of
a fixed-wing aircraft. Inspiration for this project came from news clips such as the IAI Panther and
Mini-Panther, presented on YouTube such as this example here:
Panther UAV (2 min 10 sec)

Concurrent to my DiyDrones Blog, I'll make the note here that I've completed a milestone in my super stealthy secret classified aerospace engineering summer project. The video and more information can be had on my DiyDrone entry:

I was reading about Matt Keennon of Aerovironment, and came across this archive article from the AMA website, about 6 or 7 years ago.

I figured I'd paste the link here for later reading, but from the skipping over of the article I have done, and especially the last part, I see no reason or way the AMA can ignore FPV or UAVs. They must accept that FPV, UAVs, and other advances in model planes are the future. The spirit of the Wright brothers is persistent despite all external forces.

So finally, after crashing this thing too many times while trying to hand launch it, I've finished the landing gear modules. Using the existing shoulder joint on the plane, I made a set of spring steel gear by twisting, shaping, and bonding the wire into the shape with carbon fiber wrapping.

In the post below, I've posted the CAD image of the "Accipiter." I figured I would add the real thing.

The photo, dated last month or so ago, shows the culmination of 4 months of work. I had been trying in vain to flight test it in the middle of winter. It finally flew a few weeks after, near the end of January. It has only flown 5 minutes (total); after seeing the scary stability margin it demonstrated, I've redone the tail section from an A-tail to the double-conventional depicted in the CAD image. I've also been working on the CAD model to design the landing gear.

This is the "Accipiter" modeled in Autodesk Inventor 2009. Most of the day to get this far. Still have the vertical tail surfaces, motor, and control surfaces to place.

So after a few weeks of sporadically studying for the Technician Class of the Amateur Radio License, I finally took the test this evening. I got 100%! So now off to studying for the General class, and perhaps some thought on how I'll use this beyond FPV.

Making a website to showcase all my experiments, like Mr. Rc-Cam does with, has always been a fancy of mine. I've started with a Google site ( ), but no time to work on in. So I suppose I'll be even more simple by maintaining this here. Get ready.....

Hello World!

So there's the first post of my blog.
