Electric starter: 1.1 KW integrated
Ignition: Double
Installed dry weight (liquids 5kg): 58 kg (battery and liquids not included)
Standard delivery includes:
• The engine with integrated alternator, water pump, oil pump and electric starter.
• Rubber mounts (dimensions same as Jabiru and UL power)
• Fuel pump, fuel filter and injectors
• 2 ignition coils, spark plugs and ignition leads double ECU and loom
• 2 water temperature sensors (1 for ECU and one for instruments)
• Oil pressure and oil temperature sensor
• Oil radiator, oil filter, oil tank with breather system and hose + connectors
• Exhaust kit adaptable to your aircraft is included with lambda probe.
• The liquid cooling system (radiator, hoses and expansion tank) are not included.
The different aircraft / helicopters equipped, required different cooling configurations. It is too difficult to anticipate a solution for every installation. Attempting to provide a universal solution would be both inefficient and overly expensive.
The weight of the engine completely installed with liquids is 63 to 67 kg depending on installation. This weight does not include the engine mount or propeller.
The actual TBO time is 1500 hours.
Options:
Plywood crate (FAO-IPPC-ISPM15), packaging and handling
Extra fuel pump
Redundant injection system
Warranty: 2 year
The 6 cylinder serial production started June 2015. Tests on the dyno started in July 2013. First installation was done on a German helicopter from EDM Aerotec in June 2014 (CoAX-2D). In the meantime 30 engines were delivered to helicopter companies. Middle of 2014 the 6 cylinder was also installed on a plane. Because this engine is very similar to the 4 cylinder with a lot of common parts that have already proven to be reliable, we launched this engine in the middle of 2015. The power is 125 with a maximum torque 283 Nm.

At D – Motor we design, develop, produce, assemble and test all our products in our Belgium factory. (Super Flow test system)
Our basic configurations (LF26 and LF39) are delivered with addons. Choose the right addons, and we deliver your engine at your doorstep!
Our engines are made for the light weight aviation market. We are proud to deliver engines that consume approx. 18 litres of fuel, weigh approx 70 Kgs, and deliver from 90 to 125 HP !
All our engines are injection engines, controlled by our redundant FADEC units.
Our engines are light, compact and flexible in connecting to your airplane or helicopter.
Our engines are light, compact and flexible in connecting to your airplane or helicopter.
The Propellor Flange is a important part of your engine! It delivers the induced Horse Power to the propellor. We make the flanges in aluminium, light weight engine = light weight parts!
We have several lenghts, depending on the space you have between the propellor and the engine. Be sure to give us the correct lenght when ordering a LF26 or LF39 engine!
We provide the following lenghts:
L079 = 79 mm
L089 = 89 mm
L099 = 99 mm
L109 = 109 mm
L119 = 119 mm
The backplate connects our engine to the airplane, helicopter or drone you power with our engine(s). The backplane hold the engine, by means of silent bocks and rubbers, and houses the starter. A backplate for a starter on TOP, at the rear, … is different.
Send us your type of aircraft, drone, fixed wing or helicopter when ordering one of our engines !
We have several Backplates – be sure to indicate the one you need !
Beware! In the UK no physical level indicator is allowed. We have two types, with and without level indicator. Send us the correct info before we ship your engine!
Oil pressure sensor >> ECU (FADEC)
Our ECU (Engine Computer Units) are redundant. Three computers decide, based upon the sensor readings and the pilot handlings, how our engines should perform and react !
The basic input sensors are :
– Hook sensor
– Lambda sensor
– water temperature sensor
– oil temperatore sensor
– rpm input
At D-Motor, we have integrated all three computer nits in one box.
4 connection outlets are provided to the host and the sensors, one RS422/CAN BUS connection is available at a Sub DB9 connector on our ECU.
Our software will decide on the fact if it is operating a LF26 or LF39 engine how to react, so you do not have to worry about which ECU to choose.
The mapping tables are loaded in our factory, based on the type of aircraft you use.
Follow our communication for important software updates of your ECU !
