SAB Kraken...
Has anyone here built a SAB Kraken yet? The model includes some unique features, such as the gearbox, and I'm curious how the model is to live with. The model was released during RunRyder's hiatus so the entire discussion of press releases through the first builds is missing.

Anybody got one and care to share their thoughts?

It's funny, on the "other" site there was a race to see who could pre-order the fastest.

Anyone have one?

A friend has one and I believe loves it. If I didn't have an entire fleet of Aligns that is the heli that I would buy. I like the engineering on it. There are many feature that show outside the box thinking. It is fresh an new and very impressive.

BTW welcome back

I haven't owned or flown a Goblin of any size but this helicopter makes me consider one. How do "regular" Goblins fly and how is this one different? I assume the difference is more than whatever FBL unit you might have installed.?.? Is the head different? Is it a CG thing?

Also... How do you like the gearbox. When the first press releases of the model came out it said "oil filled gearbox". My understanding is that it is an semi-enclosed grease filled gearbox. Initially I had assumed it was a gearbox like you might see on a turbine model. Do you have any opinion of the drive train?

What I like about it is how modular it is. Goes together quickly and is easy to work on. Wiring is very easy too!

Well, it’s hard if you’ve never flown any goblin to explain how a goblin flies. All I can say is, you won’t be disappointed!!!

I've been putting this post off for a while now. I'm hesitant to talk about a model I don't own.

When SAB announced they were releasing a new helicopter that eliminated the classic pinion/spur setup and had replaced it with a "sealed" gearbox, I was ecstatic. I had wrongly assumed there would be oil-filled, truly sealed, gearbox similar to what you might find on a turbine helicopter. I have been waiting for someone to produce an electric model helicopter with a drive train that has one input shaft for the motor and two outputs for the head and tail.

Yes the Kraken eliminates the large spur gear and effectively allows the canopy to be much narrower, but it still seems to incorporates all the complexities of a belt/gear driven model helicopter.

Anyway... The model seems to be well liked by those who own one. Maybe someone can speak to it's reliability and maintenance.

I like the up-high esc mount on the Kraken - it allows for a much shorter electrical path to the motor and FBL as well as CG. That wires path is nice too. I also like the sectioned canopy (as opposed to the wrap-around Goblin) for ease of use and complete look.

The head is almost the same with just a few more O-rings for damping. They did not go with the HPS2 which is interesting and they abandon the very natural 120 deg servo spacing of the Goblin.

And the extra weight of the enclosed gearbox with grease (just slung on its walls) instead of oil is of questionable advantage. The addition of the tail jack-shaft is more complicated than the Goblin direct belt drive, and adds one more vibration source. Lastly, the tail boom is not directly mounted to the monoblock but the CF side frame which is not as rigid IMHO.

Curious the heritage-rich Italians would use a Norse Folklore name for this heli.

But, I'm happy somebody is still investing $$$ into the our heli sport. It's just that the Goblin was such a perfect design from the start, I think it's hard to build-upon that.

Re-issue the Goblin with:
Ti mainshaft and thrust bearings in the mast
All-metal tail box
Sexy new bodywork and boom all made from thin-section CF
Up-high ESC mount similar to the Old Speed model
One-piece plastic landing gear with bonded-in skid nuts
Rocker-style pivot spindle head with adjustable damper
Possible switch of primary belt drive to gear drive with self-lubricating material

I only have older Goblins but I would suspect that the Kracken would feal like it's flying on crack."Respect my Authoritiah!"

I would think the kraken would be very nimble especially maneuvering along the longitudinal axis and I would think the Goblin RAW would be even quicker."Respect my Authoritiah!"
