The Durafly EFX Racer has been designed from the ground up to offer
the speed (100mph+) and strength normally reserved only for high end
full composite models, but with the handling and satisfaction, only a
Durafly model can offer.
This 1100mm (43.7") span model boasts a huge list of high-performance
features that set the EFX apart from the competition. The AeroStar 3536
1780KV brushless outrunner for only the best performance. The
pre-installed AeroStar 60A ESC has been optimized to deliver smoothly
the power you need when you want it and all control surfaces use high
speed, high torque digital 9g servos (metal geared on the ailerons)
together with ball link connectors to deliver true precision and control
throughout the speed range.
The EFX Racers high performance doesnt end with the electronics.
The airframe has been engineered to be both rigid and lightweight,
utilizing both glass and carbon fiber reinforcements throughout the
model in combination with Super Compressed EPO foam and a highly
polished surface finish to deliver the ultimate in performance in the
air and the sleekest of looks on the ground. The EFX clips and screws
together in minutes. Connect the control surfaces to the servos and
install your own choice of receiver & lipo pack and you are ready to
Versatility is another of the design features of the EFX Racer. Right
out of the box youre provided with two different power options, 8x6
for 3cell and 7x6.5 for 4cell. For good all round sports performance a
2200mah 3S lipo on the 8x6 will give good speed and is recommended for
pilots less experienced with fast models. However, for true high speeds
and power when you open the throttle, a 1800mah 4S on the 7x6.5 is the
winners choice and will get you going over 100mph. Please note that only
the props are supplied and not the batteries.
Complimenting the amazing speeds of the EFX is its stunning agility
in the air. A simple under arm hand launch at 3/4 throttle from standing
gets the EFX in the air and youll have unlimited vertical as soon as
you open up to full (4S). A full house of controls (Aileron, Elevator,
Rudder) gives the EFX remarkable aerobatics performance. Loops can be as
BIG as you want them, rolls are very precise either fast or slow and
the EFX will knife edge all day long! Thanks to the exceptionally strong
airframe, high powered, high G maneuvers will not present a problem
either. The EFX Racer will never fail you, but always leave you wanting
more! Its not all about going fast and turning hard, youll find the
EFX handles exceptionally at slows speeds with both elegance and
confidence inspiring grace. This is especially true in landing where
youll find no hint of a stall and good control all the way down to the
Whatever set-up you choose and however you prefer to fly, your EFX
Racer will perform and deliver time and time again and always keeping
you coming back for more.
