    Dear john,
    Thanks for all your articles… I have a giant scale aircraft and do not know what the down thrust or side thrust is.. Would there be a problem in mounting the engine with no down thrust or side thrust.. Will this seriously affect the planes flight characteristics I want to determine this in the air through testing kindly refer me to any article that I can use to setup this airplane for imac flying
