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
We also take this opportunity to announce that
both Alan Szabo Jr. and Danny Szabo have joined the Avant Team
with Alan Szabo Sr. as the new team manager.
