To alter another persons design and call it yours shows a complete lack of ethics. No integrity period! Why anyone would trust people like this is beyond me, if they had the ability to design a plane from scratch they wouldn't have to copy someone else's product.

That nose wheel fork could be a problem. Having the steering pivot behind the point of contact with the ground is not a stable configuration. High speed taxiing could get interesting. Pulling it around on the ground will be tricky without a tow bar because the nose wheel won't caster properly. On Oct 13, 2006, at 9:51 PM, Robin Bellach wrote: > Me too. And ditto for the wing tips.

It is a borrowed design with heavier components and features that would be better incorporated from design and materials for an RV. The appearance is as pleasing as a custom car, but you're completely right if this is to be a re-sold design. I don't think this will be a commercial success because borrowed designs often don't have the engineering available to get the job done. Cross pollination of light plane to heavy plane is risky to say the least. Be interesting to see how it all falls out, so to speak.

What he has done is apply some "Yankee Ingenuity" to the plans he purchased for the Zodiac XL and scratch built his own plane. He used materials easily available in his country where 6061-T6 wasn't available. I suppose his work was very well done and he takes great pride in his results - which I feel he deserves. I don't agree with those who say he has done something wrong by altering the XL design. This is extremely common practice in the engineering design world. While this practice might be considered unethical in academic circles it is considered "High Praise" in the engineering community. The truth is that most designs are copies of another engineer's work. Engineering is not about reinventing the wheel every time you want to build a new wheel barrel. It is about copying previous designs with modifications to fit the current goals. I suppose there is a problem calling his plane a Chris Heintz Zodiac XL. Perhaps Roberto should consider calling it a new name. Since he has created a new design it makes sense to call it something new. Will the new plane fly well? Will it be a commercial success? Will it turn Brazil into a nation of pilots? Probably not. Does this mean Roberto's efforts are a failure? Definitely not. He has done the same kind of creative work done by many engineers before him. Before criticizing Roberto for copying C. Heintz's work, it would make sense to take a close look at what Chris actually did. He did not invent the airplane. He didn't invent all metal construction, tricycle landing gear, low wing monoplane configuration, or much of anything else. I think he did invent the notion of using a metal skin as an aileron hinge. Even this little creation has caused great conversation and emotional stress among his admirers. What Chris did do was create a design focused on first time builders which is relatively easy to build and produces a light and good performing plane with docile behavior. This is a great accomplishment and Chris deserves to be called one of the greatest small plane designers in all human history. I personally commend Roberto for his work. I think we could all use this as a lesson in ingenuity and think of him as a brave and creative person.

I've been flying for many years, and I'm currently part owner of a Cessna 182. I also own a recreational vehicle which I love to travel in, around the country. But what I would really enjoy, is an airplane that I could tow on a trailer behind my RV, stopping and flying wherever the scenery looks interesting. RVs seem to be towing every other kind of recreational vehicle, these days, so why not an airplane? Obviously such an aircraft would have to have folding wings, which is why I've been looking at the Zenith 701. I took the rudder building workshop for the 701, and thoroughly enjoyed it. I think I would enjoy building the 701. I also took a ride in the 701, and was quite impressed with its performance. I've seen pictures at the Zenith web site of a 701 on trailers. One plane was even being towed behind an RV, so it looks like I'm not the first guy to get the idea. But is the 701 really suited for extensive trailering? That folding wing design looks like it was more intended to reduce hangar space, rather than designed for zooming down the highway at 70 mph. Those folding wings constitute a large, flat surface of metal, high in the air. How much side gusting of wind could the plane endure before it was damaged, or worse yet, caused the trailer to flip over? It's my understanding that the folded wings are only secured by a single pivot bolt at the front, and slots in a plywood saddle at the back. Is this really enough to secure the wings for extended highway travel? I talked to Michael Heintz at Quality Sport Planes, in Cloverdale, California, last week, while I was taking the rudder building workshop. He said for extended trailering, the best method would be to remove the wings entirely, and strap them to the bed of the trailer. Then trailering would be fine. Does anyone have any experience with extended trailering of the 701? If so, I would sure like to talk to you! I like the 701 very much. However I'm also looking at a Kolb Mark III Xtra. It seems like Kolb planes get trailered quite a bit, while the 701 does not. Perhaps there is a good reason? The Kolb factory says their aircraft was designed for folding and trailering, and the folded plane does seem to look more solid and compact than the 701. I also like the fact that the Kolb does not use a wet wing, so unlike the Zenith, there is no need to drain the fuel before folding the wings. If anyone has any suggestions or advice on this topic, I'd sure appreciate hearing from you. Thanks!

See their web page: http://www.zenithair.com/stolch701/7-photo-copies.html where they state: NON-CONFORMING COPIES By Gabriel Gavard "Chris Heintz and sons, designers and manufacturers of the Zodiac CH 601 and STOL CH701 series of aircraft (built from plans only, from partial or from complete kits by homebuilders), are getting less tolerant of supposedly "improved" pirated copies of their designs. Zenith Aircrafts internet homepage recently added a new link identifying rebel copies of their aircrafts originating from Brazil, Poland and Italy. The company has been sending updates and cautionary notices to the aviation press on a regular basis regarding these "new" machines, clearly derived from the CH 701 or CH 601, clearly unauthorized. "The principle cause spurring the spread of these copies on the new light-plane market is not just the undeniable success of these two designs now commonly registered as ultralights in many countries. A prime contributing factor has been the availability of complete blue-prints and assembly manuals for all components aircraft in question from Zenith Aircraft. This intentional move by Chris Heintz has allowed hundreds of aviation enthusiasts around the world to build and fly their own aircraft, on a budget. "Making these construction plans available, while not profitable, was a generous move by Heintz in "the spirit of homebuilding". It is also having dire commercial repercussions: The designers gesture has now been dishonored and misused by a number of unscrupulous manufacturers who, by their very actions, attest to their own inability to conceive and engineer their original aircraft. Naturally, each of these nevertheless had the expertise to then "improve" on the original design. "The motivation for the modifications has been varied: Changes to avoid "copyright" infringements; advanced or complete assemblies to meet market demands (ready-to-fly, custom modifications, etc.); and "improved" performances, often sadly based on strokes of ingenious intuition by novice builders not yet fully aware that every airplane is a sum of compromises& "Chris Heintz engineers his airplanes to well-known stringent standards. Every component and flight characteristic is conceived to work in harmony with the whole from the outset. The wings, fuselage and tail; the controls, the cabin and the rest form that whole which can be appreciated in its entirety. Modify just one, let alone several, of these elements without reviewing the whole and clearly, the machine as a unit will have been tainted&" * R & D: Research and Development, but also sometimes known as Rip-off and Duplicate. I agree that anyone building an experimental may make changes, at his or her own risk. But to make a commercial copy of a Chris Heintz design is dishonest and unethical. I hope that the Brazilians will not go forward with their copycat design. If they want to sell a kit, they should design one and sell it.

Having recently sold a 701 airframe, I know this can be done because the person who bought it drove down with a trailer and took it home.

A slightly longer trailer would have allowed him to enclose the entire airplane - and it was very easy to put inside.

I figured I could even build a couple of form-fitting little cubbyholes, lined with carpet, and just slide the wings in. I suppose if you're going to trailer the plane on an open trailer, the Kolb is probably best, since it has a much lower profile, and wouldn't be as affected by the wind. But as you say, it's probably best to use an enclosed trailer, no matter what kind of plane you're hauling. Open trailers just expose the plane to a lot of risks. It would take less enclosed trailer for the Kolb, since it's just a little over five feet tall, with the wings folded. The 701 is about 8.5 feet tall with the wings folded. Also, I wouldn't have to drain the fuel from the wings, with the Kolb. But I do like the 701! Only problem with an enclosed trailer, is theft. The thieves don't know what's inside, so they just grab it and run. An acquaintance of mine had his trailer and plane stolen. He literally ended up in a remote forest, in the middle of the night, leaving ransom money. He got his stuff back. I think I'll paint MANURE HAULING, or DEAD ANIMALS REMOVED on the side of my trailer, in great big letters. Or maybe MORTUARY SERVICE - BODIES TRANSPORTED. >Having recently sold a 701 airframe, I know this can be done because the >person who bought it drove down with a trailer and took it home.

Yeah, I noticed that last week, watching a glider land, and pack up. Off comes the wings, and everything gets slipped inside a long, skinny trailer.

To some extent, I agree. In fact, his use of the Zodiac name could be considered a sign of humility: he gave due credit to the original designer. My personal choice would have been to give it a new name and simply acknowledge the basis in someone else's design, just to avoid brand confusion.... If he's planning to commercialize this work, I think it would be a different issue. Disclaimer: I am not a lawyer, and this is not legal advice. That said, I suspect it boils down to legal hair splitting. If you reverse engineer a built item, you are probably in the clear so long as you don't violate patent. However, if you create a derivative work of the plans, you probably violated copyright. I don't know whether it's a derivative work if you copy down the dimensions, rib form coordinates, etc. from the plans, enter them into your CAD package, and press Print to generate a new set of plans. Plus, the vagaries of copyright in the different jurisdictions may make things even more messy. Just my 2 cents' worth.... Ihab -- Ihab A.B.

That nose wheel fork could be a problem. Having the steering pivot behind the point of contact with the ground is not a stable configuration. High speed taxiing could get interesting.

This is with the front wheel raised as little and tied up over a stool type support in the trailer floor and also a tie in the tail hook. Off course with the main gears well tied and movement free. This way the trailer not need to be too tall. The wings will be safe in a hamoc type support to the side walls. The hamoc support we made it from strips of carpets (samples from a carpet store) carefully passed betwen the wing and the slats. The wings will be movement free with straps to the wall. the wall will have strips of foam and heavy cloth to protect the wings. This, of course is a two or three person task, for the volume of the parts, not the weight. Hope this helps. Saludos Gary Gower.
