STOL CH 701 ENGINE INSTALLATION PHOTOS: Page 1 of 2

The Rotax 912 series engine (80 or 100 hp) is the standard recommended powerplant for the STOL CH 701.  Other engine installations are not directly supported by Zenith Aircraft Co., and will affect the performance and specifications of the aircraft. Suitable engines for the STOL CH 701: 50 - 100 hp, up to 185 lbs. installed weight.

Note: The STOL CH 701 is probably the most copied sport aircraft on the market today, and there are a number of Rotax firewall forward installations being marketed as "improved" or lower cost alternatives, many with undemonstrated performance claims, and some with "grey" market (out of warranty) engines.
