I have three patents in the field of software engineering. While I don't have 20, like some of the folks I work with, I'm relatively well acquainted with with the process of obtaining them, and what it means for the company that owns the patent to have it.

Patents are used as both shields to prevent law suits, and also as ways of making money (by either suing a company who wrongfully used your IP, or by simply blocking a company from using it). How its used depends on the people running the company.

In the earlier post it was suggested that the guy patent his design. The idea would be that he should patent it so that it would protect his idea and keep others from selling a product with that design and making a profit from it.

My point is that the actual protection one gets from the patent is only as good as the legal resources you put into it. If you do not have the money to assert your patent rights, then it offers you zero protection from folks who want to steal your idea. In a perfect world, people would be more scrupulous than that. But, that's not the world we live in. Simply look at all the patent infringement lawsuits on the books. I rest my case.

The Wright brothers were so concerned with asserting their patent rights that they went out of business. They were too small to fight that battle properly. Rather than innovate more products, they spent their time and money fighting legal battles. It's sad. Had they had a lot of money to hire significant legal staff and also continue with their product development, their history would have been significantly different.

I am not discouraging anyone from filing a patent. It's a neat thing to do. I have designed a lot of things in my day, and I am frequently asked "Are you going to patent that?" And the reality is that it's generally not cost effective for my personal purposes. The corporations I have worked for have deeper pockets and they choose to apply more liberal standards to what they want to patent. It builds their portfolio and adds real value for them. They have the funds to use them as legal tools. Most of us individuals, simply do not.

Anway, I now return us to the neat NOTAR this gentleman is making. May it be wildly successful!!!

Great job!!

Here are some of the patents filed in U.S.

http://www.freepatentsonline.com/6352220.html

http://www.patentstorm.us/patents/6...escription.html

I did not spend much time in the search. International patent applies only to countries involved in the treaty, and it is very difficult to enforce. Unless, countries involved are England, US, South Korea, Japan and may be Taiwan. An approved US Patent must be filed by country and each has it's own rules.

Give you an example; what good is it to file a Patent in China where they don't enforce copy right. On the other hand, if money is not the subject, Patent granted in England and filed in US will have greater effect of enforcement.

Hi RadovanH. I've seen your previous video of the flight test. Impressive. Congratulation so far for that achievement. Just one question what will be the flight duration having the small turbine connected to the main engine? Propelling such turbine will cost some energy at the expense of duration.

Best regards

I saw the vid too. Great going. Will be interesting to see vid of the 520 flying. Adding the weight of the finished fuselage is going to change things a little. More weight, more torque, more counter torque.

...is going to change things a little... Yes just a little that can make difference between take-off and ground spinning

Weight of comlete heli is 1030g. Flight time about 4.30 min.
Motor axi 2217/05H only with "small turbine" has power consumption as with tail rotor on 75% pitch. Flying video will be next week.

RadovanH, You are a true explorer and CRAFTSMAN !! Being an old prototype machinist myself I really appreciate the quality and execution of the design of your heli.I look forward to the video ,but look forward to ordering a "kit' from you to build my own. CONGRATULATIONS !!!! Wayne

Very nice, all the best with the first flight with clothes on.

If it cannot fly on it's own, then I won't be much help....

Amen brother. Been there, done that.

JFYI, RadovanH is my new hero! Beautiful work my friend!

RadovanH, when you posted pics of your 500E a few years ago I'll never forget how cool that thing was. One of the nicest if not the nicest 450 sized 500E's I have ever seen. Now, with this NOTAR, you may have one of the coolest 450 sized models on Earth. That thing looks great. Super job, man. Very impressive. Looking forward to the videos for sure!

Superb job and great engineering work. I was suprised just how well it performed in the test flight video, thet tail looked locked in and no different from a conventional set up.......well done!

I would like to see a flight vid in the fuse too!

He who dies with the most toys is the winner!

Great work, would buy one when becomes available.
A 500/600 size would be amazing as well. Any plans for that?

Thank you very much guys.
I´m going to add a flying video as soon as possible. Now I haven´t place to fly, because there is a lot of snow and it is freezing. I have made few short flights till now.

There is short video of Czech full - size Notar.
