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.

Quality product, well designed and good quality fittings. Flies true and Is fast on the 4s. Upgraded to 6s and its blistering! Superb whoosh sound at high speed. Tough too. One of my all time favourite buysi`ve had this plane for 2 weeks now with a dozen 3s flights on it. and i`m impressed. easy to build, apart from trying to fit the rx, hand launch is not too hard. real easy to fly. stable even in strong wind. a bit of yaw wobble but that`s no problem. it really is a great flyer. far better than a purple rare bear i got from ........ what a pig! when i crash my efxtra, i`ll probably get another one. can`t wait to try 4s.Just completed mine. The stock setup works fine and gives a good starting point for all.
As I am pounding for the need of speed, I have optimized some detals as follows:
Original motor improvements: Reduction of vibration by stabilizing the front and rear ball bearing in its bearing case of the motor. It has some play, especially the rear one. A bit of Loctite or similar will eliminate that play.
Reduction of axial play by tightening the aft locker ring down to the spacers. This will reult in a RPM proof motor, taking more beating when you intend to go 4S plus...
Both fuselage servos are a bit much forward meaning that if you use larger batteries, then the GC is a bit too far forward.(applicable to 4S 2200mAh and up..) you need to throw all weight to the aft (receiver, etc.)
Handling wise one of the best I have seen. Rock stable and precise to drive close to the ground at speeds of 200km/h and moreReceived this plane fast from hobby king open up the box was very young happy with the plane assembly was pretty much straight forward and and had no problem with the cg I'm flying it on a 4s median was no problem am buying a second just in case of a pilot errorHo comprato 4 di questi aerei.
Mi diverto tantissimo con prestazioni eccellenti.
Grazie Hobby king.Great flyerGreat flyerFor 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 servo 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.

Is this a real digital servo?
Noise is generated after connecting the orange receiver and the movement is abnormal.
hi,its analoog ,you must youre orange on analoog setting ,hold the bind button 5 second in
The plane is well made al though one of the nuts for the bolts to fix the wings is not well aligned and it makes a bit tricky to bolt the wings on. My plane is ready for maiden flight on a 4S 2200mAh 40C and CG is in the range. I am looking forward to taking it to the flying field.
However, I feel upset because I wanted to order a couple of spare props for my setup and HK does not carry the 7X6.5 props and it is not a very common pitch you can find everywhere.
