Dragon speeds are not constant. Earsplitter in Imperfect Harmony was also the same speed as the Death Song, and that would mean the Thunderdrum's speed is 17. As the Death Song chased Earsplitter, but he was able to get away, so either the Death Song's speed is not 17, or the Thunderdrum's speed is way above 14.
