She Flew Out Of My Life - The Zen

This is "The Zen".

It is a 2005 kit built CH601HD that was built by Trevor Page, and sold to me & Ray Nash in 2007. At the time Ray & I had been flying Quad City Challengers on wheels / skis / amphibian floats. We wanted a faster go further adventure aircraft that was still in the Advanced Ultra Light Aircraft (AULA) category here in Canada. It was also the aircraft that introduced me to Zenair / Zenith kit planes, the Rotax 912 series of engines, and the hopeless addiction of…

"Minor" Delay

Well, I thought things were going too smoothly.  Two days ago I received the anxiously awaited prop spacer and when fitting to the prop flange, it would not allow all the bolts to thread easily into the flange.  A few of the bolts treaded easily through the spacer into the flange.  The next bolt started to bind after a few turns were made.…

CH 750 STOL Kit

March 8, 2021 is a big day for me. I ordered a CH 750 STOL kit for pick up at Mexico, MO. I'm busy setting up the workshop in anticipation of picking up the kit and starting the build. I'm like a 5 year old kid waiting on Santa!

Corrosion Proofing

Hello All,
I noticed that some builders are using a Rustolium primer for corrosion proofing. I would rather use a spray paint for ease of use instead of the brush on primer. I am worried about longevity and weakening the structure using a primer. Thoughts on this?

Incorrect rib placement for taildragger 601 HDS?

This is for a 1993 601 HDS, taildragger. 

In the tri gear drawings, the center wing ribs (from inside to out) are at 585, 665, 770, etc. on the main spar.

The taildragger replacement drawings put the same ribs at 530, 650, 770 etc (the others are the same, only the first two ribs are different).

The issue is that 6-V-4-2 (this piece helps from the boundaries of the cabin) is riveted from the…
