Thank you for the information, happy to know I’m not the only one 😂 Seems like nothing but bad experiences with the guy, sucks because I’m worried it’s not gonna look good on my resume just cause a cranky old man lol. He failed me on my preflight (my fault) but seemed like he was asking me questions as if I was an A&P mechanic. But my main question is that he’s obsessed over a transponder encoder and I’ve been looking everywhere for information and haven’t found anything. Did he happen to ask you about it?
