If you’re craving speed, the EFXtra is where it’s at, with out of the box performance in excess of 100mph+. Durafly retained spirit of the EFX Racer and focused on adding extra performance, like the incredible roll and climb rates.
There are plenty of high-performance features and new additions over the EFX Racer. The Durafly EFXtra boasts a new clipped wing (975mm) to give extreme roll rates. An upgraded 3536-1780kv brushless motor (using ultra-high-speed Japanese bearings) with a 60A Aerostar ESC has been added, and optimized, for up to 4S performance. Higher speed, higher torque digital 9g servo's (metal geared on the ailerons) together with ball link connectors provide true precision control of all surfaces no matter what speed you are traveling. We’ve even included FPV mount in the box for the Adeline junkies that love to live life on the edge.
Durafly heard your calls and redesigned the airframe to fit larger capacity Lipo battery packs resulting in longer flight times. The aircraft is stronger than ever with both glass and carbon fiber reinforcements throughout whilst keeping the airframe as light as possible. Super Compressed EPO foam and polished finish to deliver the ultimate in performance with the sleekest of looks. How fast you go depends on the propeller and battery size. The plane comes with two propellers, for the standard setup of 3S an 8x6 prop or for performance setup of a 4S a 7x6.5 prop.
Complimenting the amazing speeds of the EFXtra is its stability at low speed making hand launching and landing a dream. The FXtra is also an agile slope soarer, just remove the propeller and spinner and add, the provided, slope soaring nose cone. Once again, the airframe provides excellent stability at all speeds to make it a breeze to fly in all conditions. Imagine slope soaring with FPV.
The EFXtra clips and screws together in minutes allowing you to get in the air as soon as possible. Just install your receiver and battery and you’re in the air.

You can have it flying in about 15 mins, Great quality, very easy to put together and flies great fast and slow. Probably the best plane I have bought from HK and I have bought a quite a few!!!Out of the box this plane is ready to fly in 15 mins. Have set up control throws as per instructions but with a serious amount of expo set on ailerons and elevator. Had someone launch for the test flight but it flew straight and required no trimming. Using the 4s set up and its quick ! I have flown it against a 4s Stinger ( and I have one of these too ) and it leaves it for dead. Not sure its 100+mph as stated but it gives you an adrenalin kick for sure Only problem is I now want more speed. Its suggested a 6s and new speed controller will improve speed but now sure what battery will go in as the standard 4s 2200 pack is a snug fit.For beginner pilot I am using stabilization receiver like receiver from mini apprentice s because this receiver fit at efxtra at vertical position. I am using signal reverse for aileron n rudder. I fly by using Tattu 2700mah 3s battery. You can fly in beginner mode intermediate and experienced mode...for launch this plane please using beginner mode n this plane will fly beautyfull. Using experience mode for normal flying. YouTube https://youtu.be/oZeYKs7nHJoFor beginner pilot please using stabilization and 3s battery...I am using safe receiver from mini apprentice s because the position of the receiver is vertical n 3 mode (beginer, intermediate n experience mode) and for propeller I am using 8.5 by 5.5 from mini apprentice. This play will fly beautifully.
YouTube video https://youtu.be/oZeYKs7nHJoI am beginner pilot n fly using stabilization for this plane.... I very like this plane good qualityI didn't think the Tundra from Durafly could be topped... Until now. This EF is truly a dream. The building quaintly and flying characteristics are AMAZING. Flies on RAILS.
Find a big field to open her up with 4S. Needs a good 60 yards to land her, floats forever!
ENJOY!I was really excited about this plane when I saw the product video. I could not resist to order one. And boy oh boy....that was a great discission. The plane looks great out of the box. Nice design and great quality. Be sure to check the stickers before the first flight, because its a bit loose at the edges so you have to secure those first......That is of course if you don't want to lose them, because this thing is a rocket ! But don't understand me wrong..it is very fast, but still very maneuverable and very controllable at low speeds too. It brought a big smile on my face from the first moment. Although its pretty heavy because of the rocket setup.....it can fly pretty slow too and stable....add to that the FPV canopy(i did not try that yet as im waiting for my FPV setup to arrive) and the slope soaring nose cone....and you have a fast, fun , controlable and multifunctional plane!!Supplied with 7x6.5 propeller for 4S set-ups ,,,, but no replacement available!!!Just been prepping both my new EFXtras and just as a point of interest, the lengthwise and lateral balance on both models is dead on with either 3S 2200 & 4S 1800 batteries. My previous EFX needed 35gr.of noseweight added to stop it soaring off like a homesick angel!! Well done Durafly ... someone really did their homework with this one!Just received mine. Nicely packaged and presented. It has a real sense of quality. Looking forward to flying it. Four stars for value is down to the poor exchange rate since brexit.
