What happens when you take a good all-around airplane like the Cessna 172 and bolt a 210-horsepower engine to it? You get crazy-good takeoff and climb performance and the cruise speed you wish a regular 172 had.
In the late 1960s through mid 1970s, Reims Aviation in France produced the "Reims Rocket," a Cessna 172 with a 210-HP engine and constant-speed propeller. (Normal 172s come with 145 to 180 HP.) In the U.S., Cessna produced a version of the 172 with 195 horsepower called the Hawk XP.
Today I rode in a Cessna Hawk XP that has been modified from 195 HP to 210 HP, so you might as well call it a rocket. It has a STOL (short takeoff & landing) kit, so this thing takes off and climbs like mad. I flew with the owner as a safety pilot while he practiced instrument approaches.
This was one of the nicest places I've ever been in. It is meticulously cared for. The panel has a Garmin GNS530 GPS. There's a Garmin handheld GPS hard-wired to it, so the 530 "talks to" the handheld. There's a nice autopilot and all the other avionics widgets you could want. Between the smooth-running engine and the wool seat covers, I think I could stand to sit in this plane all day. And oh, the performance... It's more like a Cessna 182.
If only I could write out a big check!
