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 model boasts a huge list of high performance features that set the EFX apart from the competition. The 2300kv 28mm brushless outrunner (designed specially for the EFX) uses ultra high speed Japanese bearings for only the best performance. The pre-installed Durafly 50amp 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 servo's (metal geared on the ailerons) together with ball link connectors to deliver true precision and control through-out the speed range.
The EFX Racer's high performance doesn't 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. Following the supplied comprehensive manual, the EFX clips and screws together in minutes. Connect the control surfaces to the servos and install your own choice of receiver & lipoly pack and you are ready to fly!
Versatility is another of the design features of the EFX Racer. Right out of the box you're provided with two different power options, 6x5 for 3cell and 5x5 for 4cell. For good all round sports performance a 2200mah 3S lipo on the 6x5 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 5x5 is the winners choice and will get you going over 100mph. For the ultimate speed/performance on 4cell, a 5.5x4.5 is recommended for 100mph+.
Complimenting the amazing speeds of the EFX is it stunning agility in the air. A simple under arm hand launch at 3/4 throttle from standing gets the EFX in the air and you'll 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 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 and always keeping you coming back for more.

The EFX Racer is a quality plane that could 5 stars all around. The overall rating and value go down because H.K. is always out of stock on planes and parts. This is true of most of their products which is the number one reason to buy from another supplier and pay a few dollars more. What is the point of buying a plane and saving a few dollars when you frequently can't get parts.This airplane is very fast and easy to fly. My only problem with this plane as with many others is that there are no parts available. I am seriously looking for similar planes to those HK offers because other sites offer parts and product support. In reading other reviews, I am far from the only HK customer that feels this way. Get it together, HK.I received this plane last week but haven't flown it yet. It came without a rudder horn. I
Wrote in about it but all i get is the runaround. They tell me to take a picture of the missing part. If I don't have it I can't take a picture of it. Duhhhh! They know what plane I bought, They should know what a rudder horn is. HK customer service sucks.
The plane however seems to be well built. If I get the proper rudder horn I will be happy.
Guess I'll have to look in the bone yard and see whats fits.By now I have over 140 flights on this EFX Racer. Got a motor burn once because of using APC prop 6x5.5 on 4s 1800mah. I order a new NTM 3000kv instead of stock NTM 2300kv. Now I'm using graupner speed prop 6x5.5 on 3S and it fly almost like 4s on stock motor. I'm thinking replace servo on the aileron. Don't know how long stock servo would last before it die. This EFX Racer is fun to fly and it will be favorite to pack when go fly.Love this plane! Made 6 flights with it. not much but 3 where without wind and 3 with lots of wind and it still kept stabile! Its not a starter plane! But if you want to get into faster planes BUY IT :DThis is a pre flight review. The quality of the plane is great - every thing fits together neatly, foam is smooth and tough and all electrical components are functioning as expected (on the test bench. The wing feels extremely rigid with at least two spars in evidence. The Rx and battery fit in as the instructions say wit no fuss (it is not difficult to get the battery in and out) though with the battery (Zippy 1800 4S) all the way forward it is still a bit tail heavy so will need a bit of lead up front (or a bigger battery). My only criticisms are that the aileron servo wires do not quite reach the Rx (or will be very fiddly to connect) and so will need some 10cm extensions, and the horizontal stabiliser is slightly off being parallel to the wing (down slightly on the right) so will need some packing or maybe gluing. Neither issue is much but it means assembly time is increased a bit. I am looking forward to flying it (a bit nervously as I have not done an underhand launch and it feels quite heavy for its size).Got it a few days ago, first impression: a very nice plane and good quality. Tried to change the cross aluminium motor mount to the carbon one, but even with heat, it was impossible to get the 4 screws for the motor loose. Ok, i`ve to go with the alloy motor mount, and if it breaks, i need a new motor or have to try again. Now i`m just thinking how i can get my telemetry sensor inside for battery watching. As i tried to balance the plane, i found it a little tail heavy. Maybe i`ll move the ESC forward behind the motor, shorten the wires and then place the sensor there, too. There`s not much room in the fuselage, but i`m sure all will fit nice after i found the right palces for everything.One of my favorite Hobbyking models. Flies magnificently. A very aerobatic and fast plane, do not recommend for beginners, maybe as a third or fourth plane. Apart from this, it is a very easy plane to fly, tracks like an arrow and has unlimited vertical. On my first flight I ran the plane on a 1800 mah 4 cell battery with the 5 x 5 prop with no worries at all (needs some nose weight to get the COG spot on). I also fly it on a slightly heavier 2200 mah 4 cell with no problems. When you launch the model I recommend an underarm launch with about 3/4 throttle. MAKE SURE YOU GIVE IT A STRONG THROW, not a little pathetic little nudge. You MUST give the plane a strong start or it will Tip stall and crash (plenty of videos on youtube of that happening). The plane will cruise at or even below half throttle for about 15 minute flight times. With full throttle passes, about 7 or so minutes of flight time. The model glides magnificently (almost too well) so you will need to cut the throttle very early on your downwind approach to get a nice landing. The new EFX Racer comes with a carbon fibre motor mount, so you won't need to worry about replacing that in the future. Impressed with the quality of this model and it truly does perform. Thank you Hobbyking for a truly outstanding aircraft!I have a lot fun with the efx racer. Even I got some replacement parts.
After a little tuning mines goes around 230 km/h. I fly it now with 4s 65C, 60 Amp SBEC, APC 4.1X4.1 propeller and NTM 2836 3000kV. It's a rocket now.
First let me start by saying I love this plane, but it really should be reinforced a little bit more for 4S. I bought one of these and loved learning to fly fast planes with it, never crashed it but once on my first time landing, stalled a little and one of the wings hit the ground and broke the winglet off. No problem, a little CA and flying again. This was all before I felt comfortable with the craft and switched to 4S. On my second flight on a 4S battery i decided to open it up and have a little fun when disaster struck, the left wing ripped off completely and i was in smooth level flight! Of course after this happened the plane went into a death roll and hit the pavement just out of my field, total loss. Motor is done for, two of the servos stripped, not to mention the carbon rod in the wing was snapped from the separation. At first I was willing to blame this on my earlier wing tip breakoff having caused stress to the wing, but the wing that ripped off was the opposite one! I will by another, but im gonna be nervous to fly it around people...
