I am building my first plane, a Sig Kadet LT-40 kit, I am not too sure what engine and propeller would work best for this plane. I have been reading forums, newsgroups, reviews and just about everything I can find about engines, I live in Holland and OS, Irvine and Magnum engines are the most common ones, I decided to settle on an Irvine due to the fact that my local hobbyshop is an official Irvine dealer in Holland, caries lots of spares and has good knowledge of Irvine engines. But the question remaining is wich one, a .40, .46, or the .53 ?? I have read many opinions about it so I thought I would splash the question one more time and see what you all think.
