Lauren Richardson, Pitts Special S1S
Hercules have done an absolutely fantastic job of fine-tuning my propeller design to give a very precise level of performance for what is a very demanding style of high level aerobatics for both Advanced competition flying and fast, dynamic airshow performances. I wanted to gain cruise speed for transit flights without losing too much climb performance – my Hercules propeller has vastly surpassed my expectations, not only in improved cruise (my Pitts will now happily achieve 165mph straight and level, cruising at a comfortable 150mph), but in reducing engine revving during aerobatics without any real world loss of performance. It’s also less noisy than my old propeller, meaning the neighbours are much happier whilst I practice!
A fantastic product, beautiful finish and amazing design service.
Lauren Richardson is an experienced aerobatic pilot, with very demanding requirements for her aircraft. She came to Hercules back in 2013, asking us if we could produce a propeller that would be less noisy than her existing one, produce a slightly better cruise speed and not lose any ‘aerobatic’ performance.
The aircraft is a modified Pitts Special S1-S, powered by a stock Lycoming IO-360 engine (producing a theoretical 180hp).
Working with Lauren to determine what ‘aerobatic performance’ really means for us as propeller designers, led to a design that had several rounds of test flying and some subtle adjustment, before the final incarnation was settled upon.
During 2014 Lauren flew our propeller all across the UK at numerous events and airshows and has been extremely happy overall, with both the performance and the exceptionally beautiful finish of her bespoke propeller.
As an idea of the performance she is now getting, she claims a rate of climb in the region of 2,200 feet/minute, a max. cruise speed of 165mph – quite impressive for a draggy little biplane!
