Our aircraft service companies have performed a complete dismantling and setup of the Rotax 912 ULS engine with slipping clutch, including an increase of its performance. We installed Edge Performance 1621cc Big Bore Kit (10.5:1) - EP916. / 120-130HP which allows the use of 95-OCT fuel/  High lift, high power performance camshaft for 912 big bore engines is installed as well. 
The correct combustion is monitored by Lambda Oxygen probe with monitoring the values on the gauge situated on the front instruments panel.
To the current date, the engine has 165,2 hours of flight time.
The airframe flight time is approximately 332 hours.
We have modified the water and oil cooling of the aircraft for the enhanced performance for TOW version.
The water cooling system contains 100% more cooling area compared to the standard tows with the Rotax 912 ULS engine / 2 large radiators/.
A water pressure gauge was installed to measure the water pressure in the water cooling system and Rotax FRANZ water temperature thermostat.
The engine includes a certified DETECO Oil chip detector, which detects metal particles in the engine’s oil and is indicated by a warning light.
The area of the oil radiator has also been increased with another serial oil radiator including a Rotax FRANZ oil thermostat. Oil temperature can be also controlled by manual air inlet flap installed at the inlet of the oil radiator. Oil ctch tank is installed as well.
The oil system also includes a capacitive low oil level detection in the external oil tank from the Czech company DINEL, indicated by a warning light.
The engine is Rotax ULS2 category and is ready for the eventual installation of governor for hydraulically adjustable propeller.
Due to the long experience with Dynamic WT9 aircrafts, the front landing gear leg has been reinforced.
The fuel system is modified for towing mode with a second fuel line joined directly to the engine.
The aircraft is equipped with , among other analogue instruments ,  MGL EMS-2 engine instrument with LOG-1 logging device where measured engine data are stored on SD card and a Kanardia Horis 80mm flight instrument.
We installed a Red Box FT-60 flow meter with fuel computer capability in installed MGL
