After a "heart incident" Dec. 2019 I received two stents and in Feb. 2020 my Aortic valve was replaced (to correct a birth defect) at the Ottawa Heart Institute. My Private Pilot Medical was suspended. I resigned myself to not being able to fly again. Feb. 2021 I felt so good I that I passed my pilot medical which Transport Canada placed "Under Review" because of the replacement surgery. Yesterday I received my medical "Unrestricted Class 3" from Transport Canada. It was a long tedious trip…

To change the front bungee CH601HD, CH701, CH750 or and Zenith with bungee cord front suspension. Simply hook bungee around the rear mount tube, slide up the nose strut, then slide loose end of bungee over the end of a 1/2 inch drive ratchet handle which has the 1/2 inch drive inserted in the open end of the front bungee mount tube. Lifting up on the ratchet handle will stretch the bungee easy. Once over center the bungee slides down the ratchet handle onto the front bungee mount tube. KISS…

I'm not ready to give up flying.... and I found an aircraft abandoned 16+ years in a hangar. In February with the snow waist deep the new owners of the hangar were considering calling the salvage yard to dispose of "The Cherokee". The new owners of the hangar had a Aeronca Chief and Luscombe and no need of the Cherokee. I agreed to buy the Cherokee and hire the AME Chief owner to completely go through the aircraft and recertify it. A new zero time engine and prop after all the spar…

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…

Check this YouTube channel out if you enjoy "Grass Roots"  flying videos. Mix of GA aircraft and the CH601HD / CH701 aircraft. CH601HD (both taildragger & tricycle gear) flying skis. They fly in Ontario, Canada.

I have not posted much in the last few years, preferring to lurk in the internet shadows and follow the adventures of others. I still answer questions quickly in PM sent through the web site. The 2005 CH601HD rests quietly in the hangar its systems "mothballed"..... ignored the past 2 years. Like an unfaithful boy friend my fancy had turned to another aircraft. A 1976 Citabria GCBC a friend with too many aircraft was generous enough to loan me. I learned to handle the evil "tail wheel" gear,…

Bungee have a 5 years replacement life cycle based on the color code on the bungee. The CH601HD has a nose gear bungee, and 2 bungee / main gear. All bungee 1080HD. Other builders have asked me how I replace main gear bungee. Pictures are worth a thousand words... and I hate typing.…

Does anyone have a set of the older style CH701 / CH601HD Zenith / CZAW floats?

I'm bored these days without a project, so I'm thinking my CH601HD would be cool to fly on floats. Anyone have a drawing for the front steerable nose gear. If I remember these were compressed air…

Here is a real product to wake up your Rotax 912 80 hp engine.

Failure of the Supercharger simply means you have to fly on the original 80 hp.

Here is a gently used Rotax 912 80 hp for sale.

I know the owner and aircraft history. Its good.

The Rotax 912 80 hp is great engine for the CH701 or CH601HD series aircraft. I have flown both models with the 80 hp Rotax and they fly great.

First flight of Mac McCullock's CH750 registered AULA in Canada. Rotax 912S engine. Mac did a days CH750 type training with me prior to 1st flight.

Since posting pictures on this site I have had lots of requests for information, and pictures of my 1450 Amphib. float build.

Zenair has an instructional web page set up just for this purpose.http://http://zenairfloatassembly.com/1450A/ . It is sort of hidden away unless you are looking for it. Go to this page and look over the instructions for both the "parts kit" and "pre-drilled kit". You will notice the…

I think most builders have at least one slow leak tire on their aircraft. On mine its the nose gear tire, it leaks down over a couple weeks while the mains have never leaked. I was thinking about putting tubes in the tires, but that adds extra cost and weight (I assume that is why tubes are not included in the kit?). A fellow builder Bob Stuart (CH701 plans only) suggested removing the valve stem and injecting (syringe) 5 - 10 cc of anti-freeze then installing the stem and inflating the…

My CH750 is powered by the Rotax 912S engine. To date I have 90 trouble free hours on the engine with no adjustments required other than tightening a radiator hose clamp. While flying the other day the engine oil pressure started to fluctuate and go full scale both directions on the D180. This really gets your attention! I selected a field for a forced landing, but after flying the approach with Rotax humming along happily (all oil temps & cylinder temps normal) I reasoned I was risking…

A question for all the Zenith builder & fans out there..."What ever became of the Zodiac Gemini CH620?"

I have the factory information about the aircraft it. I stumbled across the literature while going through a stack of aircraft sales pitches I collected over the years. For those of you who have never heard of this aircraft it looked like a it was a version of the CH601HDS series, with retractable tri-gear and twin Rotax 912 80 hp engines on a low wing. It was a two seat…

I have gas caps that leak when I go flying. This is evident by the fuel streaks down the top of wings from the filler necks after I land. I suspect this is from the position of the filler neck & fuel caps is steep turns. High wing tank leaks in a turn. I also noticed that the right fuel tank level was always higher than the left after going flying.

The tanks would start out level if left in the hangar over night. I went to dip the tanks after flying and heard a "whoosh" upon…
