Thank you for the information about Viking 130 shutoff. The check list was also very useful. I will probably steal both from you but not without a thank you.

Could I pick your brain sometime about Phase I testing and preparation.

My email is

Hi Patrick

the fairings worked out well

way too time consuming to make them myself

purchased them from Jeff Garrett on the forum

needed to fill some pinholes and prime and paint them

pop riveted them in with washers under the head of the rivets

use a heat gun to get them to conform to your wing/flap area BEFORE


Quite satisfied

my brother and I built a CH 750 STOL with aViking 130 and a three bladed (68") Whirlwind prop and we are just 4.5 hours into our flights tests and wishing for better weather here in Maryland.

I saw the 19 Oct data that Jan posted from your static engine run and wondered what prop pitch was used...

I also saw that you are "playing with Viking's data logging tool." I am not familiar with that... Could you point me in the right direction?

Thanks, Bill Cooper

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,

Hi Patrick

Sounds like Oshkosh was great-maybe next year for me.  Still have concerns on mounting stabilizer.  My plans call for tolerance of 0 degrees down and 2 degrees up.  Is there an advantage to mounting with x number of degrees down.  Is performance and handling better-how about level or nose high flight and elevator travel?  Still building airframe and corvair engine- Went to Fla end of April and picked up my short block from Dan and WW with new billet crank and 5th bearing and 2850 cc kit.

Thanks-Fred Schutt -601XL builder

Hi Patrick

Congratulations on your plane in EAA Sport Aviation. I will be installing a corvair engine in my 601. I  have a question for you.  I found many dicussions - from builders and ZAC on changing the angle of stabilizer- both up and down from 0 degrees for better performance and control.  Did you change degrees up or down and if so how much?

Thanks- Fred Schutt

Patrick, I'm going with Chevrolet, Corvair, T091RH which is the block serial number.


At 4:15pm on August 25, 2012, Dan Dempsey said…


The thing that worries me about how you described your engine is that if I describe mine the same way, there would be at least 2 aircraft with engine Chevrolet Corvair Serial Number 1.   Does it matter?


At 8:15pm on August 23, 2012, Dan Dempsey said…


I'm starting the certification process and was wondering how you filled out the Affidavit of Ownership form 8050-88 on the line for the engine manufacturer model and serial number.  Is this general motors and the stamped serial number on the block, or is like the plane and I'm the manufacturer and serial number is 1?

It is looking more like an airplane every day!  I can't wait to see it in person.  I camped out at Sun-N-Fun last week next to Pietenpol builder Dick Navatril.  He says you guys are in the same EAA chapter.


Good luck,
