Perfomance

The PP-XYS  will have the reliable and powerful Textron Lycoming 180 hp IO-360 B engine, turning a 74" Hartzell constant speed propeller. With this setup, the estimated performance by the manufacturer is the following one:

MAXIMUM SPEED (SEA LEVEL).................................................... 190 kt/ 354Km/h

CRUISE SPEED (75 %  @ 8000 ft).................................................182 kt/338 Km/h (TAS)

RANGE @ 75% .............................................................................1260 nm /2334 km

RATE OF CLIMB.............................................................................1800 fpm

SERVICE CEILING..........................................................................20,000'

STALL SPEED (no flap)...................................................................54 kt/100 km/h (IAS)

STALL SPEED (full flap)..................................................................50 kt/92 km/h (IAS)

TAKE OFF DISTANCE..........................................................................475 ft / 144 m

LANDING DISTANCE...........................................................................680 ft / 208 m

ROLL RATE....................................................................................... 190º / Sec

 

This performance is clearly visible in the 1998 results of  Sun 100 Race , hosted annually in Lakeland, Flórida, where Larry Kinder averaged 235 mph (378 km/h) in a 100 statute miles triangle course. It´s important to stand out that Larry´s Mustang II didn´t have any aerodynamic nor engine modification. Here are the results :
