The Coolest Thing *EVER*

Formation RC Flying

This is a video of my seawind flying in formation with a small fishing boat.  The boat was running flat out while I was holding the aircraft on the edge of stall.  There was barely any wind that day so we were able to do several out and backs.  If you’ve never flown from a moving platform, let me just say it is really weird and really easy to let the aircraft get way far away from you.  Videography credits (if there are any) 🙂 go to my Mom.

Building Openembedded for Overo on Fedora 14

Building Openembedded from scratch

The primary build instructions for building openembedded for the Overo processor can be found on the gumstix.org web site here:

Fedora 14 Specific Fixes

Follow the instructions at the above link.  However, there are several places where the standard openembedded build breaks.  Here are the Fedora 14 specific problems I encountered with specific fixes and work arounds.  This is a moving target so if you run into new issues, feel free to let me know and I’ll update this page.  In all these cases I found solutions by googling, so if you have encountered …

North Pacific Debris Gallery

NOAA Debris Research Cruise

In the spring of 2008 I joined the ATI team on a NOAA research cruise into the “North Pacific Gyre”, AKA “North Pacific Garbage Patch” — an area north of Hawaii the size of Texas where floating plastic debris collects.  Plastic can break into smaller chunks but it doesn’t really decompose, or it degrades so slowly that it is accumulating much faster than it is disappearing.  This leads to an increasing colleciton of junk and garbage on the surface of our oceans and is an ecological problem.  I’ll leave it to others to debate the magnitude …

Tracking Ocean Debris in the North Pacific

The Search

On April 2, 2008 I found myself on a 224′ NOAA research ship, the Oscar Sette.  We were sailing about 1000nm north of Hawaii in the middle of the Pacific Ocean. This was day 10 of a nearly 3 week cruise.  Our mission was research. The task for the day was to search for debris. We had entered the North Pacific Gyre two days earlier. This is often called the “garbage patch”. A debris field of floating plastic junk the size of Texas.  It is made up of human generated plastic waste that never really decomposes, instead it …

Launching Update

Update on MiG-15 Launching Technique

Here is a launch tip for anyone who’s struggled to get the Hobby Lobby MiG-15 airborne reliably:

First, recognize that at FULL throttle, there is a small tendency to want to pitch up (probably due to the large mid-T tail configuration more than thrust lines.

Second, recognize that this is not a prop plane so there is no prop wash flowing over the control surfaces. All control surface effectiveness is due purely to forward speed. During a hand launch, forward speed is at it’s slowest and control surface effectiveness is at it’s lowest.

The problem: …

Hobby Lobby P-47

Introduction

Hobby Lobby recently introduced a neat P-47 warbird model.  It has a 40″ wing span, 4-channel flight control, retractable landing gear, and comes receiver ready.  It includes servos, motor, speed control, and even a suitable battery.  All you have to do is some basic assembly, install your receiver, and you are pretty much ready to go.

Construction

Here are the tail surfaces as they come out of the box.  Everything is pre-hinged.

Here is the fuselage as it comes.  The motor and speed controller are already installed.  Servos and linkages are installed.  Even the cowl comes pre-installed:

Here is …
