PIPER CHEROKEE PA28-180
The Foothills Flying Club owns this aircraft. Built by Piper in 1964, this particular airplane has a low-time engine & prop.
This PA28 has 180 horsepower fueled by electric and engine driven pumps. This is a fixed pitch prop and runs around 9 gph. It's a nice, fast, and economical way to travel.
CESSNA R172K Hawk XP
Almost certified on a slightly more powerful 172. Built by Cessna to meet the higher HP demands like a 182 but able to keep the cost down - enter the Cessna 172 XP.
The XP has typically about 35 more HP (160 vs 195), is fuel injected, and incorporates a constant speed prop, and is a tad heavier.
Constant speed props allows better control over fuel consumption, power, and have controls in the cockpit to manage things differently (EGT, MP, Fuel Rate Gauge).
I'm renting this one from CFC and this summer (2015) they will put the floats on it. If I can afford the training, I will ascertain a seaplane endorsement.
