The main flaw seems to be the lack of forward firing armament operated by the pilot; the Roc had a single Vickers .303 machine gun and the Battle had a .303 Browning for this purpose but something larger would have been more effective buried in that thick Hurricane like wing; maybe a pair of 20mm cannon?
