Video Cameras Used in Flight

Posted on January 8, 2013 at 4:45pm 7 Comments

Several people have asked about the video cameras that I've been using.  I've posted a few videos that include views from inside the cockpit (with audio), and views from outside the cockpit. 

I have an NFlightCam GPS+ (about 1 year old), and a GoPro Hero2 (about 5 months old), generally using both cameras at the same time on my test flights. 

These small video cameras have been a big help in my Phase 1 testing.  It's helpful to be able to "go back and review what…


Moving Day for the Zodiac Project

Posted on June 15, 2012 at 2:53pm 6 Comments

On Saturday, June 9th, several EAA Chapter 25 members gathered at my house to move the Zodiac project from it's humble birthplace in a Minnesota garage to a local airport.

The day began with one group meeting at the EAA chapter hanger for some early morning prep and cleanup operations, and another group meeting at my house to prepare the Zodiac for transport.  Several people displayed great stamina by participating in both operations during a hot, windy day and under a…


Cleaning the Canopy for the First Time

Posted on June 19, 2011 at 9:46pm 1 Comment

The canopy on my Zodiac was coated with engine oil which had been sprayed by the prop blast during initial run-up testing.  On top of this oil was several months of accumulated garage dust, grit, and debris.


I've noticed a rather disturbing tendency for visitors to rub the canopy in what I believe is simply an instinctive desire to make a clean spot.  Given that it's summer now, there are more people stopping over, and more people wanting to reach over and wipe off part of…


An Australian Adventure

Posted on May 1, 2011 at 10:30pm 7 Comments

Recently my wife (Mary) and I journeyed to Australia in celebration of her 50th birthday.  Being long-time EAA members and homebuilders, part of our vacation planning included establishing contact with Australian homebuilders who lived in the regions we were going to visit.


We've always enjoyed meeting fellow aviation enthusiasts.  Some of our most enjoyable times have been in the company of aviators who we've met at various places.  From small fly-ins at places like Brodhead…

Hello Patrick,


you are a good thing ahead of us regarding the Viking engine,
so I can ask you something maybe.


1) What is the distance from propeller shaft to the ground and
2) do you use a nose wheel spacer

3) what is your propeller diameter


Thank for your efforts in advance and maybe I can also throw a
stone in your garden (german saying)


Have a nice Sunday and best regards

Hi Patrick,

maybe you remember my mail about our nearly same time maidenflight.

In this day I was looking the Viking engine  Forum and what did I found?
Patrick Hoyt is redesign the engine of his plane. I and my friend will visit
Viking next week, take a look to the engine and discuss technical issues
with Jan. I´m very sure that we will buy a Viking engine for our Zodiak 605 XLs.
I´m hoping firmly that we are both very satisfied with the engine and the
support  from Jan.

Have a good time and greeting from Germany

Hi Patrick. I'm Jeremy I just started building a 650 and was wondering about the corvair engine your running. How are they and what's the pros and cons about them? What's the fuel burn and such thanks.

What's the altitude of the field you fly out of?  Maybe it's the guys near sea level that are having to make them richer.. Do you think it's a factor?

Patrick, are you running a MA3-SPA carb?  Did you have any issue with it being too lean?

I open up the jet a couple thou and will be putting it back together tomorrow.

Really nice article in Sport Aviation.  You hit so many of the points that I had during the building process.  I think the article goes a long way toward describing the experience.  Even the compulsion or long time knowledge from and unknown origin, that you would someday have to do this.  The only other thing this big in life is raising kids.

Hey Pat, I'm flying that Jabiru 170 out of KFCM now. My finishing kit is on its way and after I am done with that I will do the wings. Got my Sport Pilot license back in July so it looks like I should be flying it next summer...

Dear Pat, hello I met you at a Peteinpole meet
In Wisconsin few years ago. QUESTION? I'm about to set up my electrical system , and
where exactly mount the buses? I did not want to mount them on the back of my panel.
That would be too little space. SO I wanted
to find out where you mounted yours?? Thanks. Peace. Mike Festa

Hello, Patrick

I'm about to cut the top forward skin (to make avionics access panels), and was wondering how to make it water tight...

I see that your 601 also has these panels

How did you go about water proofing it?

Thanks in advance for your comments

Pat, have you found out yet where your flat tire was leaking from?  I have 5 years and over 500 landings on my original tires and tubes.  On my last annual after 4 years of flying, I noticed more wear on one side of the tread on both main tires so I turned the tires around to wear the other side.  I popped the wheels apart and the tubes looked fine so I re-assembled and re-packed the bearings.  I have not touched the nose wheel at all.  I make sure to keep the pressure up as I have seen low pressure spin a tire and cut the stem.


Good luck,
