Twiddling my thumbs

Ordered the finishing kit for my 701. They said it won't ship until late September. Building an airplane requires a lot of inspiration and motivation maintenance as it is. We've all heard of the high percentage of projects that take more than a decade or never get completed. I am dedicated and determined to my project in spite of the odds. I would like to drop a line in the old suggestion box if I could. Zenith please be more informative with your orders with regards to pricing and shipping.…

Poor performance at higher Altitudes

I fly my 701 out of a 7000' airport, L35, and have a 912 engine with high comp pistons installed to produce about 90 hp at sea level. Plane has the fixed slats installed. The plane's performance is so marginal that I can not take a passenger because the plane will not climb over 50 mph with nose abnormally high just to stay level in the air. However at lower altitude airports of 3000', performance is better and there is better flying margin and I can climb at 400 fpm solo.

The plane…

Landing/Taxi Light Kit Install - Help

Hello All,
I’m working on installing my landing/taxi light on the left wing as instructed from the optional Zenith sub kit on my Cruzer. It is clear that the lens is meant to be removed to service the bulbs. The problem I’m having is that the riblets on either side don’t seem to allow enough movement to remove the lens. Has anyone installed this kit before? What am I missing? Is there a trick to removing the lens?

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.…

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…

Ignition module failure on my Rotax

Recently, the trusty 912S in my 701 has been, well, not that trusty. The symptoms started subtly about a year ago, with slight difficulty starting. Used to be, you couldn't count the blades before the thing sprang to life. Now I was counting 6 or 10 seconds, and having to mess with various combinations of throttle and choke - probably because the lack of immediate start was causing flooding.

Anyway, I had an annual inspection coming up, and even though I have my repairman…
