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.
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 tailcase gear system is a work of art on itself. Designed to be lightweight and rugged it holds a very innovative gear 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.
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.
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 base that minimizes cracks from flexing and vibration
