Bristol Hercules demonstration
Another demonstration of the very same Bristol Hercules engine as seen before on this channel. This was shot at the BorĂ¥s airshow in Sweden this summer to the enthusiastic crowd's delight. Sort of an abrubt ending to the clip but nevertheless the sound is even better than in the previous clips so turn it up and enjoy!
