I have done a search and found a lengthy thread but still not sure of the info I read. My question is what engine does everyone recommend for the GP Lanceair ES? I'm thinking about getting a Saito 100 and mounting it inverted to save the cowl apearence. Speaking of which, is there any problems mounting this engine inverted. I have a Saito 82a now mounted sideways, but, I have no four strokes mounted inverted. Thanks in advance for everyone's opinion.
