Hi all-Newbie here-Just finished the empennage for my 9A and anxiously awaiting delivery of my QB wings and fuselage from Tony Partain. I've ordered 'lectric Bob's manual to learn about electrical system. I'm also interested in purchasing some type of primer on traditional aviation engines. I'll probably end up with a 320 in my 9A. Would appreciate any recommendations regarding a good starter text to learn more about aircraft engines.
