5 - Dave Dashaway Air Champion

5th in the 5-book series by Roy Rockwood (house pen name of the Stratemeyer Syndicate.) There are times when being a great aviator pays dividends far beyond what Dave Dashaway gains from flying through the air. Such it is when he is asked to fly a new aeorplane in a competition for the manufacturer. It is he who can show off this new air speedster to its very best. But as he and his friends prepare for the contest, there are those who would sabotage their attempts at even getting to the airgrounds for the contests. Unscrupulous people who would stop at practically nothing. A mystery in the form of stolen and presumed forever lost jewels occupies some of Dave’s chums time and thinking energies, but they are there to help when needed. During the contest, a syndicate bent on winning actively cheats, but Dave would win anyway if it weren’t for a sinking shhip in a lake that he absolutely can not let go down. He sacrifices the race but saves the day and is rewarded when he believes he has failed.
