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.

very strong construction. Flies great!Great plane, very stable at low and high wind condition.Very good construction.Fast! If you like to fly fast it is very recomendable and fun.You can have this flying in about 15 mins, great quality and flies very well fast and slow, probably the best plane I have bought from HK and I have bought quite a few!!!
I also have the red one but the blue one is faster :) !!!Easy and quick to put together, flies like its on rails fast or slow. Have only flown it on 1300 and 2200 4s, balances better with the 2200. Could do with better servos but they seem up to the task so far. Easy to hand launch, bit over half throttle with a gentle underarm launch.Had a couple of flights with the new EFXtra and it flies very well. My only criticism is that the slope nose cone is very flimsy and it's not available as a spare part. Sort it out!come tutti i modelli Durafly che ho comprato è perfetto...si monta in 30 minuti. E' velocissimo, preciso e plana come un aliante. Lo consiglio...grazie Hk
