2018 West Coast Gathering?

Posted on February 16, 2018 at 12:46pm 5 Comments

I am considering putting together another gathering during the Arlington Fly In.

Would anyone be interested?

This would be at KAWO (Arlington, WA) during July 6, 7, and 8.

Activities could include a Zenith Fly Out. We will also have access to a runway for flight activities during the fly in.

An Inexpensive Cell Phone Trigger For Your Preheater.... That Gives You Piece Of Mind

Posted on December 30, 2017 at 1:58pm 1 Comment

I wanted to finally reveal an electronics project that some of you may want to build.

It is cold outside, the engines need to be warmed for long periods of time, and no one wants to go to the hangar and wait for hours while the engine slowly soaks in heat.

This solution is called the “Hangar Buddy”, and it is based on an incredible project by Maria DeGrazia. You may have seen it in the EAA Experimenter under the name “piWarmer”. This is my version that has been…


The 2016 West Coast Zenith Fly In Report

Posted on July 13, 2016 at 3:00am 5 Comments

The inaugural year of the West Coast Zenith Fly - In is now in the books, and it was a success.

This event was held in Arlington, WA during the annual (and great) Arlington Fly In.

Despite very threatening weather, we had seven zeniths show.

A 750, a 601, an 801, and four 701s. Two of the planes were from California!

We also had about a dozen active builders join us, which may be the most rewarding part of any fly in. Ideas and tips…


Training On Grass: For Fun And Safety

Posted on April 14, 2016 at 2:55pm 18 Comments

It has become old hat to complain about the decline of General Aviation. We can rant about the costs, how airports have been fenced off, or any number of ailments.

This tract is a little about one of those symptoms, a little about how to make flying more fun, and about making flying safer.

There is a vicious circle, a fully developed spin that we must recover from. Something that used to be ordinary, but is now feared.

Something that is fun, but potentially…


A Forehead Slapping Moment That May Save You Frustration

Posted on January 24, 2016 at 11:56pm 4 Comments

I have spent the past five months tracking down a strange problem. It was a problem that confused me, A&Ps, and lots of very smart people.

It was a problem that sent me down a path of inspections, repairs, experimentation, and lots of test flying.

It was a problem that was ultimately solved by two cents with of zipties.

When I pulled back the throttle on my 912ULS powered (550 hours on the engine) 701, the engine would start to get rough around…

My wife and I were one of the few who made it to Arlington this year and we did so with hopes of getting a look at some Zenith planes.   You were very helpful and let both me and my wife sit in your plane and bug you with a ton of questions.   My wife and I left there and much to my surprise, she said to me "We need to get a Zenith"   OK...twist my arm!!!!

Just my way of saying thank you.

Have you ever had your aileron controls seem to be heavy during higher winds aloft?  Control is smooth and effortless on the ground, but in mid-day flight during periods of 10mph or less winds it seemed harder today.
