After 117 flights on my B-17 and to many crashes, (mostly pilot error) have decided to hang it up. My B-17 squadron at Apollo Field in Van Nuys, CA "The Award Winning and World Famous B-17 Squadron" have agreed it was a wise decision. Have ordered a new one will mod it with all the changes on the old one. But before I make them, plan on flying it stock out the box to see if it flies any better than the original. The props were the main issue. Too flexible. Changed them to MAS 9x7's. Some the squadron pilots changed to FMS B-25 props, but as of now, FMS is out of stock. If I change to MAS props, need to cut the motor shafts shorter and can't use FMS props.
