Sab Goblin New news

[jhheli]

We are very happy to finally resolve all patent conflicts with Compass Model and all production is now resumed. We are still in process of patenting our new main gear system so we can release more pictures and manual as soon as possible together with the first shipment.

[alexvan]

Great news, but they are also saying what we were suspecting: the delay on first batch has been due to the patent issue. Is this a too artful interpretation? :roll:

[jhunter]

Is because of a redesign of the materials used in the main gear.

[worldofmaya]

Seams like the have some patents in the drive train, at least that's what was posted about the delay of the manual release.

Why is this so important?
I just want my helicopter. I am absolutely thrilled that it has been finalized..

[MaSt0RaS]

where was the problem with compass?

[gww528]

The main rotor grip "arms".

Great news, the only part that worried me a bit is the quote.

and all production is now resumed.

I hope that means after the Christmas break, not that they stopped production while resolving the patent issue.

and why is there a problem with compass..!?

[gww528]

they have a patent in Germany on the design

I agree with you. It isn't so important. I just noticed an apparent contradiction with previous notices where SAB announced that the patent issue didn't had any impact on the schedule.

But you are correct: it's amazing that currently they are on track!

Man compass has some balls

Hey your parts.look like our parts were sueing, ohh and by the way how do you like our new tdr'ish landing gear :rotf

Actually they worked that out with TDR...

[fusionsx00]

So what is it a compass or tdr?

I guess that explains the dialog in the video

[lotus7]

Where's the similarity in the landing gear?
TDR has ali tube skids and the struts are solid i.e no triangular cutout in the struts
TDR has 4 parts , CompassWarp has 2 parts with each strut/skid cut from one pice CF

The similarity in the design is in the way the anti rotation bracket is installed

They were in contact with Jan Henseleit and got an okay for designing it the way it is.

OMFG!

Still don't undertsand why people want to fly 3d with a light E90's @2200rpm what a waste of energy IMHO!!

[heliaddict2424]

New main gear is it a different material?

[gww528]

New main gear is it a different material?

Yes, it will no longer be metal.

So your saying that you didn't see a dramatic difference in performance between the parts of the video where the heli was flown at 2000 and when it was flown at 2200? I sure did.

[djamgils]

don-dadd, wasnt it 1600 and 2200 in the video?

Still don't undertsand why people want to fly 3d with a light E90's @2200rpm what a waste of energy IMHO!!

Completely agree, there are even people who fly 2400+rpm on a 700size. that is even more :Slap

[Dumbthumb75]

In his write up about the design philosophy behind the TDR, here is what Jan Heneleit says:



"In connection with the development of the Rigid numerous test flights with a logger data capture were carried through, which persuaded me to refrain from the exaggerated present max rotor speed hype. Thanks to light models with flybarless main rotors it is not necessary any more to race with a rotor head speed exceeding the limit of 2000. The properties when flying straight on are even fantastic at 1300 rpm at the main rotor. Every flybar head helicopter would pitch up hopelessly at these manoeuvres. Most of the 3D figures can be flown because of a lower rotor disc load also using a more moderate head speed. So more than 1800 rpm at the main rotor are unnecessary when flying this helicopter. The logger data show that the efficiency of the blades decreases rapidly with increasing head speed, so that most of the energy is wasted. For the same flight condition "Hovering at one position" 570W is required at 1300 rpm at the rotor and at 1850 rpm you already need 1000W. At more than 2100 rpm 1500W are required, i. e. nearly the triple amount, although you do nothing more than hovering.
This result shows clearly that the flight time can be increased considerably, if the rotor does not constantly rotate at full speed. All these results have contributed to and influenced the choice of the speed reduction and the recommended drive of the Rigid."


Of course, the text is about the TDR, not the Goblin, but think about what he says for a minute...
