UR-1 Devil

Race Plane Kit

Our first aircraft, designed for the Air Race E.


Fully electric and capable of extremely high speeds, it's a totally bespoke racing aircraft created for those who need speed.

Specificities :

The UR-1 kit includes all components in carbon, aluminum, wood and electronics. Parts are custom cut with minimal additional material to allow for inherent final adjustments.

Carbon and fiberglass shims are also provided to adjust bonding gaps. You will also have access to all technical data and assembly diagrams. Glue and tools are not included.

Time for the realization of the project:

We estimate it at 800 hours. Customers with licenses in Switzerland can order fully assembled and registered aircraft.

Estimated performance:

  • VH: 270 KIAS
  • MTOM: 400 kg
  • BEM (ex. Battery): 180 kg
  • Battery mass: 120 kg
  • VS0 : 55 KIAS
  • VS1 : 65 KIAS
  • Battery capacity: 14 kWh (50 MJ)
  • Motor power: 150 kW
  • Endurance:
    • 1:20 Hours at VY
    • 6 Minutes to VH


Three-phase motor controller

The beating heart of our electric planes. These motor driver units are designed to work with EMRAX 348 motors and our future low profile aircraft motors. They offer best-in-class performance in terms of efficiency and weight for high power applications.

Technical specifics:

  • Output power: Available in 150 kW
  • Weight: 4 kg
  • Conversion efficiency: 92%
  • Input voltage: 800V DC
  • Dimensions: 265 mm x 225 mm x 85 mm
  • Water cooled, 22 l/min


Battery system

The critical element of the UR-1 Devil, its power-optimized battery system. Equipped with a water cooling system and a triple redundant fire protection system. The Firebolt is designed to efficiently and safely deliver 800V of continuous current in the lightest package possible.

The enclosures are made from our proprietary lightweight composite panels that have been tested to withstand 1000 degree flames for 15 minutes. Electronic controls and internal fire stops virtually eliminate the risk of a “battery” fire, but each enclosure is additionally capable of containing a fully developed battery fire and safely venting gases to the sea .

Technical specifics:

  • System weight (12 Units + CBMS): 120 kg
    • Weight per unit: 10 kg
  • Operating voltage: 562 – 750 V DC
    • Unit voltage: 47 – 63 V DC
  • Charge/discharge rate: 2 C / 10 C
  • Maximum output power: 150 kW
  • Water cooling: 22 l/min divided into 12 units

UG-2 Bullfinch

Take-off in 2024

The UG-2 Bouvreuil will be the first genuinely practical battery-electric aircraft. With performance similar to traditional aircraft such as the Cessna 152 and Piper Warrior, it is capable of completing all standard missions expected of light civil aviation at a fraction of the cost per flight hour. The $100 burger will cost $100 again!

This aircraft will be available as a carbon fiber kit. It will be ready for manufacture from 2024, after the first flight of our prototype. Pre-orders are available with a 5% deposit.

Specificities :

This kit includes everything needed to build and fly a UG-2 Puffin, including all powertrain and battery system components, carbon composite laminates, and wood and aluminum components. Parts are roughed close to final dimensions to allow for final adjustment.

Carbon and fiberglass shims are also provided to adjust bonding gaps. Access to all technical data and assembly drawings is provided. Glue and tools are not included.

Building time:

We estimate a construction time of 1200 hours. Customers with a Swiss pilot's license can order a fully assembled and OFAC-registered aircraft.

Estimated performance:

  • VC : 120 KIAS
  • MTOM: 1000 kg
  • BEM (e.g. battery): 300 kg
  • Battery mass: 500 kg
  • Maximum payload: 200 kg
  • 1 pilot + 1 passenger
  • VS0 : 50 KIAS
  • VS1 : 95 KIAS
  • Battery capacity: 100 kWh (360 MJ)
  • Main motor power: 150 kW
  • Autonomy and endurance: 500 NM + reserve, 4 hours at VC
  • Minimum charging time: 1 hour (DC charger required)
