Zenith 701 Humanitarian Pod

Our drop tests went 100% to plan.  We now start working on how to get our new project to reach the tougher parts of West Africa with the 750 platform (more load, more range!).  Thank you Zenith and Rotax for making it possible!See More

Zenith STOL CH 701 Air Drops help African communities grow...

Research and Results for Fuel Supply Solutions Rotax 912iS

Finally we have reached the point where we consider that we have expressed how we have established our fuel system for the 912iS in our test bed CH701.  No, it does not contain all that we wanted to, but we feel that it conveys the points about what we have done, why we have done it and what we would prefer to do.We LOVE LOVE LOVE the engine and the airframe combination.  It is a great airframe and a great engine.  A marriage of heavenly proportions, for us and what we use our aircraft for, at…See More

Header Tank

In our line of operations we often experience a lot of turbulence at low level (we are approved to operate below 500' for aerial dispersal and supply drops).  We also get some long, at times fast, descents.  With this combination of events we have decided that we really want a header tank for a variety of reasons...  We have simulated 'uncovered ports' in ground tests, and do not like the VERY unlikely possibility that it could cause.  By taking the 'Tee'ing of tanks to a low point 'air being…See More

Building an airfield...

Posted on November 29, 2012 at 10:28pm 7 Comments

Building Zenith aircraft is a pleasure we all enjoy.  Being a little more than 'naive' my team got to build the aircraft, the hangars and the airfield - as well as work on the regulations and approvals process for Ghana!  Today, we administer the training and assessment, as well as licence issue for the National Licence (LSA equivalent) on behalf of the Authorities.  It has been a long journey, and we have further to go.…

Hi Jonathan,

Let me know how I can help with the African fly girls.  I will not be at Oshkosh this year. We were there last year and do not go every year.

Hi Jonathan,

Thw newer Zenair amphib are easier to construct and setup. I think I would go for those. On the CH701 they are pretty heavy...So watch for this.

Hi Jonathan,

Sorry it took so long to answer your comment about the Anti-skid tape found at Rona (construction store)! Went on EASY ! Very nice result and very cost effective. I don't think you could tell the difference between this stuff and what is sold by aircraft shops. Look at the pictures... Easy to cut and very STICKY! Can't pull it off afterwards.

Just for fun...I'll post some cloudy days too...fyi, I spend more time at or below 500 than above 500ft.

The wheels and tires are the same ones Zenith was testing on the CH750 last summer. It's a good upgrade if you do off airport stuff. Not as good as the Alaska Bushwheels, but not as expensive either. The Alaska Bushwheel tires run about $2000 USD. The total upgrade to what I'm using was about $1100 with shipping. Most of the cost is for the new 8" wheels, axles and brakes. The tires are only about $30 each. The stock Zenith stuff is great on beaches, grass and dirt. The bigger tires are needed for rocks and uneven ground. Some of the gravel bars I land on will really rattle your teeth with the stock equipment. When I put on tthe bigger tires (21 X 12 X 8) and drop them down to 6-7 psi (less if I'm very light), it's like landing on marshmellos. See the Zenith test video at (http://www.zenith.aero/profiles/blogs/testing-larger-bushwheel-tires) I'll get you the details if your're interested.

Jonathan,
I hope and pray that you will soon make a recovery from malaria. I have enjoyed reading how you put those STOL Zeniths to good use!
