Building a BF109F-2
The Completed Model

The completed model is a rendition of the BF109 flown by Oberleutnant Max-Helmuth Ostermann. He reached the rank of Oberleutnant while flying with II./ JG 54. He was awarded the Knight's Cross on September 4 , 1941, after 29 victories. On August 9 , 1942 , he was attacked and shot down by nine Soviet fighters near Amosovo. At the time of his death, Ostermann's victory total stood at 102 and was the holder of the Knight's Cross with Oak Leaves and Swords.

The completed model weights 20.5 ounces ready-to-fly with a Mega 16/15/6t motor, 8-cell 1100 niMH battery pack, Castle Creations Phoenix 25 ESC, 2 Hitec HS55 servos and a Hitec 555 receiver. Wing loading is approximately 18.5 oz per square foot.

My BF109F-2 is 100% balsa and was finished with .50 oz fiberglass cloth and resin and Testor's Model Master™ acrylic paints. Colors are official RLM numbers taken from Profile Publications. Panel lines were added with a #2 lead pencil. Large insignias were painted and smaller ones were developed in Photoshop and printed on Avery Lable stock. A light coat of Krylon satin clear was applied over the model to preserve panel lines and "stick-on" insignias.

Flying Qualities: This model is a fast and responsive. It is recommened for experienced e-modelers who are comfortable with flying similar aircraft (like the Jim Ryan warbirds). Equipped with the Mega motor it really moves but will fly at 2/3 throttle without any problem. The Clark Y airfoil and washout allows the plane to be slowed downed for an easy belly landing in the grass. As of 03/15/2005 150 flights have been made and the aircraft has proven to be an excellent flyer. BF109F2 Video Clip #1 3.3 Meg 2:00 In-Flight Video - Fly By's #2 1.2 Meg 12 seconds
