So far I have 4 heli's and out of them so far I love my honey bee FP because the damb thing can take a beating and snap back together and keep flying. My Honey bee king.. umm not so much. I'm not really into 3D and am just really looking for a nice heli that is simple and fun to fly. So far the HBFP does it for me. It flys in 5-10mph wind and after a crash I just snap the head back on, check to see if the blades are tracking and fly again.

If this bird can do that and fly better than the 64#C1 walkera's then I'll buy it.
I also have a HBFP and love it for it's durability, ease of maintenance and cheap parts. But to me, it's just a trainer, I'm looking for a high quality, easy to fly FP heli and this one seems to be the only one out there. I was even looking hard at the ECO 7 Jet Ranger until I discovered it shipped with a styrafoam fuselage. At over $600 for the lipo version, I can't see the expenditure. Anyway, one of the characteristics I love about the Quark after having looked at those videos several times is that there seems to be NO tail drift, so maybe that shaft driven tail rotor is the ticket for this FP bird! At any rate, I have not found another FP heli out there that matches the criteria I'm looking for: quality, parts availabilty (I know Hirobo will make sure US distributers have adequate supply) and foremost, easy to fly indoors OR out.
Are there other brands/models out there that I haven't reseached yet that might meet my requirements?

I don't really understand the 45 degree paddles to be honest. Maybe someone who understands these things can chime in.

The flybar on a single rotor heli needs to be 90 degrees out due to gyroscopic precession. The main rotor causes a gyroscopic force in a direction 90 degrees later after a change of pitch is applied to the flybar. The coaxials have two rotors so one rotor cancels out the gyroscopic affect of the other so the flybar is at 45 degrees. So that makes sense (to me anyway) but it doesn't make any sense that a single rotor heli has the flybar set at 45 degrees.

The piccoz/havoc doesn't have any true cyclic control afaik so I guess it doesn't really matter about gyroscopic precession. It just hovers, add weight in the nose to go forward and use the tail for yaw.

This is different and I don't understand it.

Incidentally the flybar and the rest of the head components should be quite durable....the foam rotors will ensure they go first before theres any chance of damage to anything else. And they will break often....hence the xrb blades usually ending up with parcel tape wrap.....and this thign will fly a helluvalot faster and in more extreme maneouvers. Wayhey!!

I hear what your saying about the foam blades breaking before anything else and they break often but with the HBFP they don't break and other than one of the balls on the head nothing else does either it seems. This is a great design IMO. I've crashed mine so many time I can't remember them all and I haven't broke anything but one of the balls off the head. Lucky there is two and I just use that one. Mind you I always cut the throttle before impact and I have the heavier landing gear as well. Maybe I've been lucky /shrug

BTW isn't the walkera 64 c1 different from just the 64c? Thought the C1 had upgrades unlike the 64c?

Have you looked at the Compy FP yet?

SRB Quark Info with video link...
Looking at the pictures, I am wondering if it has a Bell-Hiller head?
I see 2 rods from the swashplate to the head:
1. One rod looks to influence the rotor blade pitch by
swinging the stabilizer bar so that one paddle/side moves up
and the other paddle/side moves down
(which via another rod will change the pitch of the main rotor blades).

2. The other rod looks to more indirectly affect the rotor blade pitch
by rotating the paddles/stabilizer to change the paddles' angle of attack/pitch,
increasing one paddle's angle while decreasing the other paddle's angle
(then as the paddles move through the air, the difference in angle causes
a difference in lift, which causes one paddle to swing up and the other
to swing down).

----------------
On another topic, I saw a video somewhere of the Quark in stable hover
while the hands are off the transmitter controls. I wonder how hard it will
to adjust the Quark to this level of stability:

1. I have seen a similar hands-off stability video of an Esky Lama 2,
but I could never adjust mine to be that stable.

2. I can adjust my XRB Lama (tethered) to that level of stability, but it
takes a large amount of time adjusting to reach that level.
As an aside, I find that the worst part of breaking the XRB blades is
not the cost of the blades, but the time needed to adjust the XRB after
mounting a new set of blades.

---------------
Oh yes, I have a GWS mini-dragonfly (similar to an HBFP) and I find it
more sturdy than my Esky Lama 2 or my XRB Lama.
Nothing broken yet on my mini-dragonfly, despite a number of rotor strikes
on stone walls, steel doors, etc.
Meanwhile, at similar or lower speed collisions, my Lama 2 eats inner-shafts and my XRB eats blades (after the packing tape mod).
But my XRB and Lama 2 are less likely to hit anything.

On the Japanese page, Hirobo claims that it has a Bell-Hiller head.

That's really odd...most FP helis use a Hiller arrangement.

It might explain the $400 MSRP, though.

Don't think its released yet.

Not sure how a bell-hiller head makes it more stable.....more likely more twitchy.

They say (whoever "they" are) that the Quark will hit our shores here in the states late Feb/early Mar.. You know what that means, might see it here in April!!??
Do a Google on "Hirobo SRB Quark" and you'll find a short video (youtube) and a real short review by a guy in Switzerland that got one a week or so ago.

Good pilots can make anything look good. What concerned me more was the hovering in cvlex's video link. It wasn't bad it just wasn't any different from any other micro...didn't particularly appear any more stable and there also seemed to be the odd tail glitch. Didn't make me think that this is anything special and therefore worth the extra moolah.

Different look for the Quark.

Two additional body styles for the SRB Quark, the Airwolf and Bell 222.

HIROBO SRB airwolf (1 min 25 sec)
