The Butler LoPo canopies are designed to complement the company’s HX Series canopies, which are rated for much higher weights and speeds. Butler LoPo canopies are intended for environments where the high performance of the HX-line is not as critical, and budget is a significant factor. The LoPo-series are rated for speeds and weights that are equal to, or greater than, any competing products from other companies. Butler LoPo canopies feature a simpler version of the slider that is used on the HX-series canopies. The flat slider provides many of the benefits of the slider used on the HX-series and is also covered under the same patent. However, the flat slider is much simpler in design and construction and has contributed to the lower cost of the LoPo canopies.

* Knots equivalent airspeed: the calibrated airspeed corrected for adiabatic compressible flow for the particular altitude.
** Knots indicated airspeed: the speed shown on an aircraft’s pitot-static airspeed indicator.
† FAA certified weight limit which results in a rate-of-descent of 24 ft/sec at sea level.
†† Butler Parachute Systems recommended weight limit which results in a rate-of-descent of 20 ft/sec at sea level in order to reduce the potential for landing injuries.
