On October, 8, 2005 in Buzovaiy airfield the first launch of powered sailplane AL-12M with a retrcatable power-unit has been perfomed. The powered sailplaine was lifted up by Aerola's Chief Design Engineer Nikolay Konononenko. The sailplane with power-unit was delivered on airfield on a car roof rack and was rigged up in field conditions. After propeller pitch and engine were adjusted the sailplane has driven out at the runway by itself. The six flights have been accomplished. Good handling and climb ratio has been registered and stop/restart of the engine in air and also centering of the prop  were checked. The purpose of the test flights was getting of preliminary perfomances of sailplane with the power-unit based on Solo-210. During tests the power-unit  was  fixed. The retraction of power-unit in flight  will be tested the nearest time.                                                                               

  

  

  

 

19.03.04 was made first flight on the sailplane AL-12 by the chief designer of the company, sailplane pilot Nikolay Kononenko.The glider has been delivered to the air field on a roof of the car, quickly rigged up and prepared for flights.  Air towing was made by a trike. Pilots of the sailplane and the trike had been marked very comfortable conditions of the towing. Were performed one low altitude flight and two flights on a circle. During flights the behavior of the glider in the turn, spirals, on the high speed is checked up.The glider has shown good stability, controllability, effective work of flaps. All witnesses have noted very low noise level and high glide ratio at landing approach.
