601 Flying Carpet

Posted on April 7, 2009 at 8:17pm 2 Comments

Getting more time in on my 601 XL / Corvair. Cruised about 100 miles Sunday, 3000 RPM, about 110 MPH TAS at 5000 MSL. The air was smooth as glass and the Corvair never missed a beat. I've been tweaking the cowling to improve cooling, and this flight saw about 230 deg. oil and 350 - 370 cht's. I'm running the Ellison carb, and pull the mixture back just enough to bring the EGT's up to 1300 - 1350 deg., using a Cyberdyne mixture meter for guidance. This Zenith flies like a dream, and turns a lot… Continue

Testing Phase 1

Posted on March 31, 2009 at 10:14pm 1 Comment

After 205 inches of snow this winter, I'm finall able to start knocking off some test time on my 601 XL. I flew the 11th hourof testing this arternoon. What a teriffic airplane ! I'm getting more at ease in it with every flight. The Corvair is running strong, and I'm seeing 1000'+ climb rates with my 190# and full tanks. I initially had to adjust the horiz. stab. angle down 2 deg. I'm still tweaking my cowling a bit to improve cooling at high climb rates. The flaps are a real asset on the XL,… Continue

Thanks for getting back.  We met at Sun N Fun this year.  I misplaced your email address that you gave me. I hope to start my project some time in the near future but for now I will save towards my project.  

I was an AFS student to Brazil in 1975 and we spoke about you hosting AFS students and the adventures that one has with being involved with AFS.

Well any way.  I soled in June and then had a medical set back which I'm still recovering from. Hope to resume my training for S.P by the end of July.  

If your are in the Clearwater, FL area please let me know so we can meet.  Email is

Have a great day.

It was a pleasure to meet you at Zenith on Sat. Thanks for the look see in the cowling and explaining your lift reserve set up.

I just got back into town from Co. Springs. The paper work is still up on the Goggle Picasa site. The links on my Dynamic Balance Comment are to pictures of experiments. In the document section download the 'How-to' paper that details what I did and an Excel spreadsheet showing the resultant graphs and calcs. There is a newer accelerometer chip xx335 at instead of the one I used but it should work as well.

I moved the Zenith this morning. I will be attaching parts this weekend.
I am excited about the tow bar.
I'll let you know about using a test pilot after next weekends lessons.
A friend of mine is buying a really nice PA16, That is a tailwheel airplane. He will be going to Brokenstraw on Sunday to see about tailwheel lessons. We will pop in to the Corry airport too.

This should be the kind of weekend that you have been waiting for to get some time in that new airplane.
I am hoping that I will gain enough confidence in flying the 601 when I go away next week for lessons, that I will be able to be the test pilot. If not, I will need to talk to the guy that did the first flight in yours.

I'll see you at Sun-N-Fun.
We are moving the last parts to Meadville on Saturday morning.
I hope to be taxiing (Sp.?) in a week. I am going to LA to do a few hours in a 601XL with an instructor to get a feel for the airplane on the 21st.
