Excellent information. Thank you.

Perhaps Kin can address the differences between the CopterX four-blade head and the other 450-sized four-blade head on the smartmodel.com.hk web site.

And now we have the nice looking four-blade head from rusheli.com too. Holy cow.

It's probably too early for this but can anyone sum up the differences between the heliartist and rusheli fenestron units?

Here is a CAD drawing of the Fenestron System.

It is belt driven and has blade pitch.

Theres been alot of ideas that hit the drawing board, Looks good but I still dont think the fanfare and hype should be made until they at least have a working prototype and able to actually produce the part. I understand about building up the hype. Lightening heli did and we see what they came out with.... I hope they dont put the part out on the market and leave it up to someone else to try to make it work right. I fenestrom tail would have to spin extremely fast while the main rotor must turn at a very much lower rate , especially with a scale head. Im sure eventually someone will get one working and produced.

Looks scarily like the LightningHeli Paper weight.

If these things have to be really fast, I'm wondering if they'd be producing some 450 auto gears to speed it up. I having trouble seeing how the speed could be increased using the belt alone

You are right. New gear ratios that drive the belt is the only practical way to speed things at the tail end up.

The Lightning Heli system is completely different from the HeliArtist and Rush system.

Here are some photos of the LightningHeli Ducted Fan Tail Rotor:

Is that a pulley after the pulley? Hey, that could speed it up nicely I'd think.

I gotta say, if someone actually makes a working version, I think I'd have to make a heli #5 (and I thought 4 was too many, lol), that would be really neat

Suspicions confirmed. HeliArtist has released products earlier that were originally available under the LightningHeli name. Hope that's not the case again here since LightningHeli's attempt at knocking off and downsizing the Vario fenestron was a disaster.

Who's System is this? It looks different from the Lightning Heli system that I posted? Is this the Vario? I've always seen Carbon Fiber Blades on the Vario.

If that is the system they are now/going to produce, I do no see any "up speed" mechanical thing inside. That mean, the tail is spinning at the same speed as normal TRex450?

The photo posted on Lightning fenestron tail that has a lot of problem (See above)... I know that. It was from "Adrianli". One of my flying buddy.

That one I seen it in person...and it is really SUX. Oh! the tail shaft can't even turn properly due to the inner shaft (for controlling the pitch) is rubbing against the outer shaft.

No "up-speed" mechanical.

U can ask "Adrianli" for it.
