I know nothing about helicopters but it looks like the Hughes/Schweizer 300C as flown by Dennis Kenyon at Shoreham. His displays are legendary & he does things with an ordinary helicopter that should be almost impossible. Much as I dislike the things he could keep me out of the beer tent where I would usually head for during helicopter displays.
That kid's naturally biased but his claim about his Dad being the best in the World is debatable. Dennis Kenyon recently retired after 30 years as a helicopter instructor. He's also a former world freestyle aerobatic champion. He was given the freedom of Shoreham Airport on his retirement.
Check out the vids posted here, including a short clip of his routine at the World Helicopter Championship last year.
