The Walter-LOM engine is manufactured in the Czech Republic and has developed an excellent reputation as a low-cost and reliable aircraft engine.  Represented in North America by Moravia Ltd., service and spare parts are readily available.
Moravia is working together with aircraft manufacturers to establish Walter-LOM as a standard engine option for the builder/pilot.  Modern features found on the proven engine, as well as the value of the complete engine firewall-forward package, will make the Walter-LOM engine popular with many builders.
