Santa with a 701 Difference!

Posted on December 12, 2013 at 9:59am 8 Comments

I guess that we are a bit like a 'sensible Santa' in our part of the world... we fly over the African Bush and look for communities that need some health education and then drop them a package!  (no chimney, no reindeer, no toys)... our Rotax 912iS powered 701 works really hard... and today we dropped over 100 packages to rural communities - some which have never had even a motorcycle to them!…


The nose job....

Posted on September 2, 2013 at 10:32am 0 Comments

As we work ever creatively towards using the Zenith STOL aircraft in practical applications, in the heat of the tropics, we are currently working towards a concept for improved cooling.  It has taken us a long time, but we are close to test flying the 'nose job' on the 701 with a Rotax 912iS up front.…

For those who have been wondering what is happening in Ghana - well, we have a few challenges!  You can read our latest newsletter in the PDF below... 

We are also working on a radiator gantry for the 701/750 for the Rotax 912iS (and the other Rotax installation, but we are working on improved cooling for the iS at the moment) and a really simple cowling modification that goes with it.  We expect to carry out flight tests next week, and, if all goes well, will share…


Flying with 912iS in a CH701

Posted on June 24, 2013 at 2:31am 0 Comments

One of our pilots from Brazil is transitioning to the CH701 with the 912iS.  He put a GoPro on the mount and then created with You Tube video... - although it is speeded up, it shows a lot of interesting hand movements in the cockpit... watch carefully as you see me in the right seat moving my hands around a lot!  Also check out the full and free movement prior to take off - as well as enjoy…

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.

I've been looking at your pics. Interesting stuff...I was especially interested in your camera mounts as I am currently working on a vid mount for the baggage. shelf. I've been thru a couple and about have one done that I'm satisfied with...thx for the pics.

Just for fun...I'll post some cloudy days, 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 ( I'll get you the details if your're interested.

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!
