John Morris' Z-21

Many are waiting with bated breath for the next newsletter from the Connecticut Flitzer Werke. Truth be told, we have been too busy building to get the news together, let alone file snippets online. But the arrival of the superb set of brakes from Ian Wasey was a milestone one cannot let pass. Within seconds the brake pedals were mounted to the rudder pedals and the whole kit trial fitted as you can see in the attached photo. The pic also shows the standard seat lowered by at least one inch, and the WWI Le Rhone throttle quadrant to be fitted to the Morrisov machine.

Much more before very long.....there has been a lot of progress. As Ernst Kessler would say, March every day or die.

The Connecticut Flitzer Werke makes progress every day, sometimes large, often small. But every day.

The next Morrisov missive is planned for early March. Brace yourselves!!

This week marks the sixth month of fuselage construction of the Morrisov machine; now the primary structure is complete the details are taking more and more time. Progress just appears to have slowed; in reality the smaller parts are coming along quite fast. Attached: the latest newsletter, to mark the six month milestone.

This picture of the museum quality Connecticut Z-21 looks like it belongs in the Smithsonian, uncovered for all to admire. It shows the different stages at which builders choose finally to skin the fuselage, Ivan keeping his options open for installing equipment until the last possible moment.

Ever conscious of how this thing should look, Ivan has raised the firewall bow slighty to offset the effect of shortening the forward fuselage for the AeroVee. This will allow the more rounded 'bull nose' of the prototype to be maintained, rather than a slimmer nose prevail, which would be the result of keeping that frame the standard height at the more aft position. Nothing escapes Ivan.


July 10, 2007 - Tailbay

Here's a series of pictures sent by Ivan (John Morris) of the Connecticut Flitzerwerke, showing the tailbay details, skeg, rudder cable guides, etc.

The second picture shows the balsa tail-end to the decking wrap. This is one of the few Flitzers that's actually been built this way, ie. technically as drawn. Note the string laser to align the frames.

The Z-1S in Germany and Dudley's Z-1R are both upholding the exceptional workmanship standards as displayed here by John, and indeed by many others that we've seen via emails from around the world.

It makes me proud to have designed an aeroplane which seems to inspire such enthusiasm and bring out such skills, but it's also humbling to consider the degree of faith placed in the range of Flitzer development types which have gained recent popularity. It has been my aim to ensure that these, sometimes more advanced variants like the Stummels and Z-2, plus the lightweight simplified types such as the Goblin and Meteor Speedwing, meet or exceed the performance and handling achieved by the Z-1 prototype and Z-21 'series' models. This too will be reflected in the quality of the drawings, which should provide greater clarity and require fewer updates that those added to the Z-21 over time. The Z-21 of course has been a story of increasing sophistication with the addition of brakes and motors incorporating self-starters, increased endurance, the potential addition of active trimming systems and eventually, it is hoped, a co-axial PSRU. The supply of plywood, timbers, pre-cut timber and metal kits, steel tube stock from the USA, drum brakes, and even a source of (Hoosier) treadless tyres for the standard Honda C90 wheel rims have all come about in the years since the Flitzer first appeared and offered as a plans-built only design.

I am about to get the first detail drawings of the advanced F.2 Tiger printed. Let's hope the next decade brings about even greater things.

Best regards,

October 5, 2007 - 53 liter fuel tank

Hi Guys -

Today I picked up the Morrisov machine (Z-21) gas tank from the welder. This tank is narrower (front to back) than usual as my firewall is moved back 2.5 inches to accommodate the AeroVee. But by modifying the firewall-longeron gussets (with Lynn's approval) and adding a "box" to the back of the tank between the mounting straps I have managed to add enough fuel capacity to cope with the thirstier engine (though total AUW is, of course, a consideration). Photos atached - zip folder.

Why not a bigger box at the back of the tank? You need full forward stick!

And lastly, while a tiny cockpit cutout looks racy, one must still get the tank in through that hole.

This tank holds exactly 14 U.S. gallons (53 liters, 11.66 UK gallons).

Needless to say, with this potential range the Baron will now have to add a stout piece of string to his personal preflight checklist!

Prost! - Morrisov
