A
hard act to follow...
...That's Denny Dobson and his Extra 300XS, writes Gary Parsons Many an airshow act groan when they find they follow Denny in the flying programme, as his dazzling aerobatic routine puts many more orthodox display items in the shade! Denny's finely honed skills and his love of flying have made him among the best at what he does. An established airshow act for some time, Denny has in fact only been flying for fifteen years. Taught to fly by Wing Commander Derek Day (RAF retired) in a vintage Auster, Denny had a varied career before the flying bug bit. But when it bit, it bit hard! Prior to taking up the challenge of aerobatics he spent most of his time ferrying aircraft, enabling him to gain a lot of experience in a short space of time. He has had no dual instruction in the art of aerobatics, being completely self taught. Denny began professional
airshow flying in 1992, flying
his homebuilt Pitts Special. A typical season
will see Denny carry out some sixty public displays per season, with
a typical weekend in the height of the season seeing Denny perform
at up to seven different venues, with hundreds of miles to transit
between each Performance of the diminutive 300bhp Extra is sprightly, to say the least. Composite construction helps keep the weight of the airframe down to 950kg wet, and provides a maximum speed of 220 knots with a stall speed down as low as 55 knots. Stressed to +/-10g, the airframe ably copes with what Denny subjects it to. To date, Denny will be performing his full unlimited aerobatic routine at some fifty shows this year. After a punishing display of unlimited aerobatics, including some new manouvres in his display this year - the upward accelerated spin, the turnaround tumble, the slicer and the rolling loop, Denny will first perform the limbo. He will fly his Extra at speeds of up to 300mph, at a height of only three feet, underneath a streamer suspended from two poles which are just twelve feet high. He will then perform a rolling manoeuvre to reposition for the knife edge 'ribbon cut', cutting the two-inch tape with the propeller.
