au·ro·ra:
Ancient Greek and Roman goddess of the dawn. The
bearer of things to come and mother of the four winds.
Aurora presages the begining of the future.
Capitalizing on the wildly successful FX and EFX,
Avant RC introduces its most advanced model helicopter
to date.
This is a 100% Avant purebred complete kit.
The model uses the tried-and-true and very succesful
CCPM system and the Avant Programmable Head and combines
them with the rest of a design that takes the state
of the art in high performance helicopters to a new
level.
A very slim design and low front profile give the
Aurora a very low drag coefficient that allows it
to keep the momentum in the most demanding maneuvers.
An incredibly low parts count makes this an extremely
easy to repair and maintain heli.
A very streamlined figure makes it easy for axis alignment
and orientation axis into the most precise maneuvers.
An innovative slanted battery plate with easily replaceable
straps makes it easy to exchange power packs finally
allowing for a practical way to use lighter packs
and save on flying weight
At the same time the battery plate slides and adjusts
upwards and downwards allowing for CG adjustments
without the need to add additional weights.
The Aurora uses the most rugged torque tube system.
The generously sized gears are designed to take about
9 times the actual forces while in flight so that
the pilot can use and abuse the system without the
usual concerns of the typical torque tube systems.
A 4.9 tail to main ratio makes it a very nice system
with all the tail authority you'll ever need. The
torque tube Gear Layout is the same design as the
tried and true proven system used by the Hirobo Eagle
line of helis. This also allows to accomodate for
a future belt system.
The Aurora Ultimate uses a carbon tailboom for extra
stiffness and lightweight.
The Aurora tailcase gear system is a work of art on
itself. Designed to be lightweight and rugged it holds
a very innovative gear system.
To service the gears the pilot simply loosens the
tailhub setscrew and takes the three gearcase cap
screws off and the whole systems comes out to the
right for a very easy servicing access. Also notice
that instead of using a fixed length brass sleeve
the Aurora tailcase uses an ingenious adjustable bearing
sleeve that allows you to keep the tail output shaft
without any lateral play whatsoever and prevents the
brass sleeves from eating into the gear's delrin.
Besides being extremely light the tailcase is also
very stylish. Notice how the tail output shaft is
a 6mm diameter and the tailhub is a 5mm diameter shaft
for extra resistance for those not-so-perfect autos.
The tailhub threads are made inside to minimize the
creation of fatigue cracks. It also makes taking the
tailblade grip off a single operation with a wrench
from the outside of the tailgrips. Two widely spaced
radial bearings and one trust bearing make it a very
precise tailgrip system.
One of the nicest features of the Aurora is the main
gear system. It uses machined delrin gears with a
special high load tooth profile that minimizes the
noise and rattling. The generously sized main gear
is larger than most of the standard gears lowering
the point of contact forces applied to the gear's
teeth.
One of the most advanced features is the use of a
centered sprague. In the Aurora instead of a problem-plagued
one-way bearing system the Aurora sports a combination
of sprague clutch and a radial bearing in one unit.
In this system the sprague runs on a hardened inner
race preventing the common "grooving" of other systems.
This is also kept in precise alignment by a built-in
radial bearing.
All the parts are precisely machined by completely
automated systems guaranteeing part to part consistency.
With this innovative design a very compact and light
main gear hub and constant drive system is achieved
The pinion and clutch are precisely machined to the
highest engineering standards
Precise simplicity and low parts count is always a
welcomed feature
The clutch stack uses a precision point-threaded fan hub that virtually eliminates the need to dial-indicate the fan. The Starter shaft is not attached to the clutch directly but through a one-way bearing. This prevents the starter shaft from transmitting vibrations to the frame and allows for the use of simple inexpensive starter wands.
Many nice features are incorporated in the design.
Ample room for today's large engine heads is taken
into account as well as clearance so that the head
can be extracted or swapped without having to take
the engine off the heli.
Another nice feature is the addition of wear pads
a the bottom of the struts extending the life of the
struts when landing on hard or abrasive surfaces like
concrete or asphalt
The Aurora tank is designed to optimize the location
of the fuel pickup minimizing the distance from the
pickup point to any point inside the tank. A generous
22 ounce capacity allows for longer flights and more
time for practicing.
Ultra-compact and lightweight design is a key directive
in the design of the Aurora
A slim profile lightweight epoxy-glass canopy comes
with a flexible primer that minimizes cracks from
flexing and vibration

Thanks to the economies of high volume automated production
we expect the introductory price to be $985.00
