Description

The XFly Twin 40mm Su-57 EDF 700mm Jet (XF121PV2) is a compact electric ducted fan model styled on the Su-57, built around a twin 40mm EDF layout. Supplied without a transmitter, receiver or battery, it allows you to integrate your preferred radio equipment and power components.

Its 700mm size makes it a practical jet-class model for flyers who enjoy EDF handling and jet-inspired looks in a portable airframe. Configuration details beyond the absence of transmitter, receiver and battery are not specified in the supplied information.

In the UK, operating drones and model aircraft may require a Flyer ID and an Operator ID with the Civil Aviation Authority. Ensure you meet current CAA requirements before flying.

Key Information

  • Twin 40mm EDF configuration
  • 700mm jet class

Specifications

XFLY TWIN 40MM SU-57 EDF 700MM JET WITHOUT TX/RX/BATT

Following the release of F-22 Raptor, F-18 Hornet and F-15 Eagle, XFly Model is continuing to expand its incredible twin 40mm EDF range with Sukhoi Su-57. The full-size Su-57 is a twin-engine stealth multirole fighter aircraft capable of aerial combat as well as ground and maritime strike. XFly's Su-57 is a scale replica that not only includes scale details in air intake, cockpit, nozzle and full-flying horizontal stabs, but also has excellent performance in power, speed and maneuverability.

The factory-installed power system, including twin 12-bladed 40mm PRO fan units with 1511-KV5850 brushless motors and twin 30A brushless ESCs, paired with a 4S LiPo battery, delivers an abundance of thrust for fast climbs, rolls, loops and endless fun for high alpha flying. A flight time of around 3-8 mins can be achieved with proper throttle management.

Perfectly fitted landing gear design helps keep the plane lightweight and make take off & landing smooth. Landing gears can be easily removed for hand launches to get more speed and better vertical performance.

Features
  • New V2 - Upgraded 1511-KV5850 Motors with 30A ESCs for Faster Climbs and Improved Aerobatics.
  • 4 operable channels (Aileron, Elevator, Throttle, Steering).
  • Scale replica of the Sukhoi stealth multirole fighter aircraft Su-57.
  • Full flying stabs designed for excellent high alpha capability.
  • Efficient twin power system setup delivering an abundance of thrust for fast climbs, rolls, loops.
  • Perfectly fitted landing gear design for smooth takeoff and landing .
  • Extended flight time of 3-8 mins when using recommended 4S 1800-2600mAh LiPo battery.
  • All components can be assembled quickly without glue needed.
  • Robust EPO construction.

Safe flying is YOUR responsibility.

Update 01/01/26: The laws have changed regarding operating drones and model aircraft in the UK.

What you need to do:
You must take a theory test and register with the CAA before flying most drones or model aircraft outdoors in the UK. 
There are two requirements and you may need to meet both: 

  • Pass a theory test to get a Flyer ID. 

This makes sure you know how to fly safely and legally. 

  • Register with the CAA for an Operator ID. 

This registers you as someone who is responsible for a drone or model aircraft. 
Most people get their Flyer ID and Operator ID at the same time.

It is against the law to fly a drone or model aircraft without having the required IDs.
You can also be fined for breaking the law when flying. In the most serious cases, you could be sent to prison. 

The requirements are based on the weight or class of your drone or model aircraft. 

Registration requirements for drones and model aircraft:

Questions & Answers

Real questions from real customers. Why not ask your own?
Not powerful. Just as gutless as the f22. Dives on no throttle and climbs on full. Not very stable at low speed and not enough go to punch out of anything. Very disappointed 😞
Daniel Brown / 10th July 2026
Hi, we have seen the review and just wanted to check which batteries you are using with this, the mAh, voltage and c rating as this dramatically effects performance.
Also just checking what kind of a gyro you are using as this may effect flight characteristics, we do find that edf jets need to be flown at fairly high speed to keep them stable.
