I send an e-mail to Marcello about most 100cc class twins not fitting in the cowl. He sent back info about a new 34% Extra that will be basically the same plane with a cowl that is wider toward the front, counter balancers marked on the elevator, higher main gear and some other minor mods. It will be called a 330L and should be out soon. To late for me but it sounds like he pays attention to the ideas people have to offer. If I ever need one, the new cowl should work on the 300.
