Offpiste Discovery

The 1996 Discovery was designed as a Skyfloater. It was aimed at those pilots wishing to fly for fun having found that the latest superships are demanding of skills especially in light wind conditions.

The 1996 Discovery was available in two sizes: 160 and 195. A feature of the Discovery is that it can be flown prone or seated.

The 1997 Discovery 2 catered for all weights of pilot by four sizes: 160, 195, 195S and 210. The price was £1750, rising to £1800 for the 195 S version. A retro-fit kit was available for around £100 to upgrade the Mk 1 to Mk 2 spec.

The 1997 Discovery 2 was described as glorious in light conditions due to low wing loading and featherlight handling, however once you pull the bar in more than a few inches glide and sink rate are terrible.
