About the S-300CBi
The Sikorsky S-300CBI is a light piston 3-blade helicopter mostly used in helicopter pilot training and agriculture-related missions. The S-300 was originally designed by Hughes. Schweizer then acquired all rights to the model. The company was then purchased by Sikorsky which now manufactures and sells the aircraft.
