The high-lift features of the design give the STOL CH 750 its excellent short take-off and landing capability. The STOL CH 750 light sport utility aircraft was designed to provide excellent STOL performance without the need for a lot power: Overpowering an existing aircraft is the easiest way to achieve short take-off performance (with enough power anything will take-off in a short distance!), but this requires a lot of fuel for acceptable endurance, and is an expensive, heavy, and inefficient way to obtain STOL performance, and does not provide good slow flight or payload due to the heavier engine weight and fuel load requirement.

While all aircraft are designed within certain power and engine weight guidelines, Chris Heintz has not designed the aircraft "around" a particular engine - to maximize the customer's choice of installed powerplant.  Recommended power for the STOL CH 750 (built to the Edition 2 drawings) is 80 to 140 horsepower, up to 280 lbs. installed weight.

Following are currently the most popular engines being installed in the STOL CH 750 aircraft (additional engines may also be available or suitable):

At Zenith Aircraft Company, our specialty is airframes and not powerplants. We do not recommend nor endorse specific powerplant choices.  While we strive to make a variety of firewall-forward packages and/or accessories available, we may not stock everything needed by the builder to successfully complete the powerplant installation.

(Note that some of the engines presented may not be suitable for the STOL CH 750 airframe).

About "Alternative" Engines:

STOL CH 750 designer Chris Heintz has stated: "I've designed the STOL CH 750 specifically for a wide choice of engines - 80 to 140+ hp, up to 280 pounds installed.  Many different engine types have been custom-installed in the CH 750."

STOL CH 701 airframe, before engine installationMost custom engine installations typically require a lot of work and "troubleshooting" to properly install, and may not provide the expected performance and reliability. Designed as a light sport utility kit aircraft, top speed of the STOL CH 750 is limited by its high-lift design features, and more power will not yield significant top speed gains.

An inexpensive engine may cost you less to purchase initially, but may not provide the proven reliability and performance you expect, and may need to be replaced a lot sooner than expected.

Zenith Aircraft Company stocks engine mounts and accessories for various engine types but does not provide support for the engine installations.

Alternative engines will affect performance, specifications and flight characteristics of the aircraft. Also, the weight and balance of the aircraft may be adversely affected by different engines, and the original fuel system may not be adequate or suitable for some engines and installations. Most alternative engines will require a custom engine mount and cowl. Zenith Aircraft Company does not manufacture or directly support engines nor their installations.
