Here’s some nice artwork of Al’s Chinese Hawk:
This was a fine aircraft for its day. However, the Navy’s version, the BF2C, was a fiasco. The wings of both aircraft appeared identical. However, the materials involved in their construction was different. After the Navy version was delivered, pilots noticed that it vibrated violently in a dive. Not a desirable quality in a plane with “B” in its designator code. The Navy tried several modifications to eliminate the problem, all of which proved unsuccessful. As you digest these comments, bear in mind that this all went down during the Great Depression, and that the Navy didn’t have money to waste on a run of defective aircraft!
