Cessna R172K 'Hawk XP 210 Horsepower

210 Horsepower Cessna R172K Hawk XP.

Over 300 Cessna R172K Hawk XP owners are flying with the 210 HP engine. The 210 horsepower conversion provides maximum performance for the Cessna 'Hawk XP. The high performance version of the XP has a proven reliability, kit installation is simple and no category restrictions are placed on the airplane's original type certificate. The modification is fully approved by the FAA for both the landplane and seaplane versions. The STC covers Edo and PeeKay floats and the 210 horsepower is also approved by Wipaire in their AFMS.  The Hartzell Top Prop is approved by Hartzell for this 3-blade propeller in combination with this 210 horsepower conversion.

                                                                                           R172K Hawk XP Digital Tachometer option.

The Digital tachometer & hour meter is available as an option on the R172K Hawk XP.  This tachometer is approved by the FAA for installation on 210 horsepower Cessna Aircraft Hawk 'XP as the primary instrument.  Accurate in all conditions, easy to install, provides diagnostic and performance information for the engine and ignition system and eliminates operational and maintenance problems related to mechanical tachometers and cables.

R172K Hawk XP 210 Horsepower conversion parts.

All of the work for your Cessna R172K Hawk XP aircraft modification can be accomplished by most FBO's. Installation time is approximately four to six hours. The kit includes overhaul and new dials installed on your mechanical tachometer and manifold pressure/fuel flow gauge, new fuel flow placard, STCs, installation manual, instructions and FAA approved airplane flight manual supplement (AFMS). A factory new governor and digital tach are optional. The work on gauges include a one-year warranty.  All kits are FAA parts manufacturing approval (PMA) approved. With a digital tach or new governor parts are priced considering the exchange cores are returned  (governor and gauges) after the installation.  CLICK HERE for mechanic installation instructions.

Shorter takeoff (490'/990' over 50').

The Cessna R172K Hawk XP has adequate power at 195 horses. That is why the increase to 210 horsepower causes such a dramatic difference in takeoff performance. All of the added power is destined to quicken acceleration. This shortens the distance from the start of the takeoff roll to the point takeoff speed is reached. The 210 horsepower makes the airplane sound and accelerate like a Cessna 210! Even under severe takeoff conditions the airplane jumps off the ground with an immediate and positive rate-of-climb.

Increased rate-of-climb (1150 fpm @ 81 KIAS).

As with takeoff acceleration, the additional power all goes to increase the rate-of-climb after lift off. The initial climb after rotation is much more positive. The rate-of-climb increase significantly reduces the time it takes to reach cruise or ATC assigned altitude. This reduces pilot workload (less climbing maneuvers) to reach required altitudes when crossing controlled airspace.

Less fuel burn and shorter time to altitude.

Because the shorter takeoff and increased rate-of-climb requires less time, this results in less fuel burn from the start of the takeoff roll until reaching climb altitude.

Improved decent capability.

At low pitch (high RPM) the propeller works like an air brake. The power off decent rate is dramatically quicker at 2800 RPM than at 2600 RPM. This feature can be controlled simply by setting the prop control in high RPM if a rapid or emergency decent is needed, or by setting it at 2600 RPM for a normal decent approach.

Improved ground handling.

The standard R172K Hawk XP requires constant braking to hold the taxi speed down at engine idle. The 210 horsepower conversion changes the propeller low pitch stop setting causing the blade to "flatten". At engine idle this results in less forward pull by the prop. The airplane taxi's at a safe and comfortable speed without the need to constantly ride the brakes. Also, this reduces heating and wear on the brake pads and discs, lowering maintenance costs.

Ability to log high performance pilot in command time under FAR 61.31.

Because the airplane is over 200 horsepower the pilot may log his time as high-performance according to FAR 61.31. This is very beneficial to owners, family members or others flying the aircraft to build time for additional ratings or career opportunities.

Improved STOL and emergency go-around capability.

How much difference can 15 horsepower make? A lot! The extra power all goes to added takeoff acceleration and climb performance. You really have to fly it to believe it, but the difference is a very significant improvement to the R172K.

Near Cessna 182 Skylane performance at a fraction of the cost.

Reliability.

You will receive maximum performance from your engine. The 210 horsepower is attained by removing the "D-rating" that Cessna placed on your airplane's engine. The 210 horsepower XP has a proven reliability. In essence, the modification makes the XP nearly identical to Cessna's "Reims Rocket" built at the company's plant in Reims, France, and the U.S. Military T-41B. Both of these Cessna airplanes have the full 210 horsepower capability of the IO-360 engine. Over 25 percent of all Cessna R172K airplanes have this conversion installed.

What does Continental Motors say about the conversion?

". . . no affect on the difference in structural integrity or airworthiness . . . Thus the IO360K should also provide excellent operation and service with a take-off rating of 210 HP at 2800 rpm."

Technical Description.

STC SE1436CE and SA1437CE approve the conversion of the Cessna R172K to operate at 210 horsepower. The STC's are applicable to the following:

  • Continental IO-360-K
  • Continental IO-360-KB
  • Cessna R172K landplane (all)
  • Cessna R172K floatplane
