CB100 first impression

[ehirobo.com]

We just got the delivery for the CB100 with the new 2402 tx. I gave it a quick try and it is very easy to fly. With the 45 degree rotor and the flying weight makes it very suitable for people which would like to move up from the co-axial heli. And it feature twin brushless motors so you do not need to worry about burn out motor again.

[ranger306ci]

looks to be the same size as a 4#3, right? What are the benefits of the new tx?

[ehirobo.com]

ya, this is basicly an updated 4#3B with the new rotor head. It feature a 45 degree flybar with flying weight. Which makes it very stable compare to 4#3. This new heli fly like a co-axial. :shock: And the new tx is compare to the old one is all the reverse function are done digitally now. So you do not have to deal with the little dip switch anymore. And the LCD display have back light just like the 2801.

[ranger306ci]

Not that the 4#3 is very unstable to fly in the first place! I find it do be a pretty stable heli for its size.

[David]

Yeah, beaufiful structure helicopter. A big problem is that I found the design is the same as Nine Eagles invention patented in the year of 2007 which was released on the inside back cover of the 39# issue of RC heli magzine a few days ago. Any problems if I sell Walkera CB100 helicopter? Pls help me to resolve this puzzle.

Dear David:

I am not sure but I don't think there are any issue as the 9 eagle have the flybar on top of the blades compare to walkera which the flybar is below the blades. So the design is different. Please correct me if I am wrong.

Dear all Hobby distributors and friends, Wish you consider these Nine Eagles patent issues. Wish you do not bear the unnecessary infringement. risk

hmmm,


Interesting that this thread is being watched by more that one manufacturer.....

[ranger306ci]

Yep! Feel sorry for nine eagles in this reguard, but to tell you the truth, their heli line is pretty ho hum to begin with....

[mtpenguin]

No such thing as bad publicity?

I went to their site and found no products to buy with this system of control, but they had a nice looking but plastic parted "somewhat CB 100" looking micro heli using it. Lets face it....they all look pretty much a lot alike. Nothing really new in years has come out as far as a new concept goes, outside of the impossible small size. Read some old R/C heli books like Drayk's and you will see the following rate and moment arm is way too small on these micros to work. These things will give a humming bird a run for the money. But what we have and use goes back before I was born, not saying I'm old or patent right and non-disclosure requirements have not hidden one based on E=mc2 or something;-) The current concept still needs some form of adverse yaw compensation and is held at bay by the reality of time and F=ma. This is the reality we live in. I wish, as we all do, that something new would show up. It looks like all E=mc2 is good for is designing bombs and keeping the GPS satellites in sync. What does space being relative to time, and time being relative to the observer, have to do with designing a better helicopter? I am sure if you come up with an answer that changes the basic concept then THAT will be worth patenting. But unless someone can come up with something new, like the Great Professor did with his equation, we are just copying someone else’s idea colored by our work. It might seem as if all the new ideas have just run out. That is what happens when everyone thinks alike, and why when someone thinks differently enough to be a true inventor that invents something NEW they should be protected so they can invent more NEW and better things. The Air Havoc is not new.

They seem eager to claim design goals. The Air Hogg Havoc was a blast when it came out due to its size....I guess almost 10 years ago. To me the CB 100 is a fixed up Havoc as it uses the same 45 degree stability bar/weight system and copies its basic principal, but differently than how Nine Eagles does it. It was well pointed out by ehirobo:

The design is different. You may be able to patent an "exact" design of a well known and used concept, but it will only cover the "exact" design. For a patent to be worth fighting for in good faith (big companies and their attorneys obviously excluded) and therefore worth obtaining it should not be based on the current basic helicopter concepts that require a tail rotor or other known forms of adverse torque reaction compensation, such as two rotors (attempting) to canceling each other out. The standard helicopter concept has been beat to death and doing a reasonable patent search at this late date is unlikely due the volume of interest and work on the concept. We need to remember patent law, like all property rights, is weak without money to support it in a legal system controlled by the attorneys and their clients interests. I am fighting a 10 year long lawsuit with an HOA that's board member (and HOA's attorneys) claim owns the subdivision road that's easement section goes on the border of his property, not mine by chance, that stopped my development forced to use the legal system. We have no legal system if $300,000, 4 separate attorneys, and ten years of hard fighting cannot win a case like owning a road known to be owned by others in legal documents. To think you can own a patent that is really original and protect it is hardly likely without "selling" it to a bigger company. In this case originality is in question as well as it being copied.

A patent protects, if you have the money to defend it and fight off law suits, new technology that really changes something "conceptually" and does something "differently" unlike no other before. In the US it used to be you had to the be the first (inventor) and the date of conception was important. I don't see that Nine Eagles has invented anything new outside of doing something already done on the Havoc and other designs.

If they had, I'd be forced to send them....say 20.00 dollars. Just think what would happen if people respected other people’s rights and instead of the attorneys walking away with the cash, the inventor got a few bucks from every person that used his invention. Think how much a buck for every Havoc sold would put in your pocket. We should support inventors, not attorneys.

I'm going to send Nine Eagles one dollar just in case I'm wrong. Since I don't own a CB 100 but have two Havocs I feel that's fair;-)
