THE RANGER XP (Cat A Aircraft)

 

The prime difference between the Sherwood Ranger ST (Microlight) and the Sherwood Ranger XP (Cat A) is one of wing span and wing loading. The ST has a wing span of 7.92 m and the XP 7 m, they both have the same MTOW the XP therefore has increased wing loading and a higher stall speed.
