I show several candidate engines for my 1/4 scale clipped wing Cub by The World Models. The SAITO 180, DLE-30, O.S. GT-33, and MLD-35. I go with the DLE-30 even though a little work may have to be done to the firewall because I want to go with gas and a bigger engine. I can easily go with the GT-33 if I set it up properly for the DLE-30.
