Description

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") span kit boasts a good list of design features that sets the EFX apart from anything on the market. 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. Following the supplied comprehensive manual, the EFX clips and screws together very quickly, leaving you only to install your own choice of 28mm sized motor, 9g servo's and 50-60amp ESC (EFX 50amp ESC recommended). This kit version of the EFX also opens up a host of options not easily available with the PnF. Included with the kit are the stickers sets of both the red and yellow versions of the EFX, but with the all foam components unpainted the base scheme you choose is completely up to you. The kit also provides a comprehensive set of control accessories including ball link connectors and a hollowed tip spinner for extra cooling.

When it comes to power, the EFX kit can be built as a light weight powered sports glider on a 3S set-up or at the other extreme, a 4 or even 6S speed machine! The versatility and engineering of the airframe lends itself equally well to both. Fancy a good aerobatic model for the local slope? Then don't install a motor at all, the EFX kit can be turned into an amazing sports slope model with minimal effort. In the air the EFX will not only impress you with its impeccable handling and performance at all speeds, but its agility and rock solid stability too. To get in the air a simple underarm launch from standing at 3/4 throttle is all that's needed. At full throttle the EFX gets small very quickly and enjoys good unlimited performance (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 never fail you, but always leave you wanting more! It's not all about going fast and turning hard, you'll find the EFX handles exceptionally at slows speeds with both elegance and confidence inspiring grace. This is especially true in landing where you'll find no hint of a stall and good control all the way down to the ground.

Whatever set-up you choose and however you prefer to fly, your EFX Racer will perform and deliver time and time again. The only thing better than flying an EFX Racer is flying with other EFX Racers at the same time, so get your friends and get flying!

Bit of a mixed bag this one; mine is a genuine, verified, >100mph setup and in my experience the chassis cannot deal with these speed(s). Without crashing; the fuselage has split in three places (around hatch/wing joint area), elevator control hinge failed and, more relevantly, both wings sheared clean off in flight either side of the fuselage and it came down like a shot pigeon. The only thing stopping a three piece landing was the thin square (6mm) central carbon wing-spar....plane was flapping around like a bird. Also learned never to touch the rudder as it tip stalls easily and also has an odd rotation (wiggle) around the Z axis especially in any wind; this disappears at high speed but it is a bit unnerving to see during flight.

Don't get me wrong it is one of my favorite planes and flys very well (at speed) but, at circa 100(ish), it is high maintenance. Setup; SK3 3536-1050 (carbon mount), YEP 60A ESC, 6S 1300 mah Nano-Tech, 7x6 Prop. Eagletree Data - Cold Day (8deg) GPS Speed was 103.34mph (Cold Lipo); Normal day (18deg) GPS Speed was 116.19mph (logger mounted where the hatch normally goes - peak current 35A). Would recommend getting one but don't expect it to last if you're going for glory; really requires additional strengthening at the root of the wings, stronger wing-spar and hinged control surfaces.

Nice little kit version of this plane- the foam is the strongest I have seen yet. Carbon and fibre glass reinforcement makes it a tough plane. The decal set provided is incomplete however as the main colour(red or yellow) that would go along the top of the fuselage is missing. In my case i decided on the yellow version but because the fuselage has now remained the white foam I have added my own decals to it in an attempt to make it more visible in the air.

This bird exceeds my expectations.. Gave it a NTM2836 3000 kV motor, 80A Turnigy Plush ESC (at the original spot), 4.5 x 4.5 prop and draws about 70-80 A on a 2250mAh 40C 4S battery. Some digital servo's, AS3X stabilization and a home-made carbon hatch for more space, estimate it at around 200 km/h. Seems rather stiff and agile, even in high-speed tight curves!

A strange design to some extent. The placement of the ESC in the back for example, it's just silly. Instead, I dug out space under the motor and placed the ESC there, then almost no motor cables needed at all. I also moved the elevator and rudder servos to the back of the tail. They do cause a bit of turbulence, but I find it acceptable, and the control rods result short and stiff. Ball links and clevices are of acceptable quality but make sure that the ball links don't bind. I also glued a carbon strip 1x6x750mm to the bottom of the wing for improved rigidity (it felt weak when test bending the wing). The included decals are very good, easy to apply, stick well and are strong. I use an NTM 2836-3000kv motor with accessory pack (glued a cork on the back to cover the protruding shaft). Battery Nano-tech 4S 2200mAh 45-90C. ESC 80A YEP, 5x5E prop. Servos HK15178B all around, receiver OrangeRX 610. Center of gravity as in manual (50mm). The plane is very fast and a bit unstable, you must be on top of it all the time. Has quite nasty stall tendencies, so make sure to keep speed up. Haven't measured top speed yet, but should be around 200 kph with this setup. All in all a nice kit but prepare to mod it a little to get the best out of it. Recommend.

Awesome, built mine with the parts I recovered from the ARF version I bought first (side note, don't use orange HK DSMX receivers in high speed apps)

I used 9 gram digital servos and a genuine DSMX receiver this time and its one the most locked in models I have owned. It even does snaps and flat spins!!

Get one, and talk you mates into getting them to :-)

Really like it. Bought the kit to save money and use some existing parts.2200 kv suppo motor,60a esc 7x5 prop,3cell 2200mah 35c.Not super fast yet but I wanted to get comfortable with it first.The plane flies really well launches are smooth(underhand 3/4
throttle) turns on a dime climbs and rolls well,inverted no problem.Even glides pretty well
with motor off at altitude in a little wind.Handles mild winds (10-15) without issues.Flies
slowly for first flites.Overall exactly what I was looking for in a high performance foam pylon racer.Excellent build quality and design. Large wingspan helps with visibility.Durafly
you've got a definite winner here. Hope this helps,God bless terry
