Verner engines are designed and built by the Verner Motors Factory of Sumperk, Czech Republic. In about 1998, the firm began to develop two-cylinder, four-stroke cycle aircraft engines. Information can be found on the Verner Website, which lists their dealers all over the world, including the Websites of their US affiliates, Apex Aviation, Central Florida Flyers, and FlyDiver LLC. The VM 1400 is no longer in production, but the 133MK is. Upgrades of the VM 1400 into a 133MK are available, as are conversions of the QD-1400 discussed on the Compiler's Q-Drive Webpage. The relationship between the VM 1400 and the QD-1400 is unknown to the Compiler.
