Not just juvenile, poisonous. That's an attitude that kills pilots, ones that listen to you and the ones they might have shared a screwup with but didn't.
Regarding my panel, nope. Decided against the Bendix stuff I was looking at because it would probably need a long cable run (the G/S receiver would likely need to go in the tail) and difficult hardware support.
I'm just flying right now, almost every day. It's fantastic. Today, I dropped down to the airport on my motorcycle, then practiced turns around a point and steep turns, plus I threw the plane around into some unusual attitudes, that was fun. Flew up a river for a while, feeling the effects the hills below had on the airflow and turbulence at different elevations and shapes. Found a friend's house that has an airstrip and circled once to see if he would come out, then went and tried a Chandelle based off of a description I read. It was pretty shaky, good thing I don't have a commercial checkride in my near future.
Did one fun thing, took a marine air-horn up and asked my wife to come outside and listen for it when I flew over her office (I blew it out the little 'smokers window' on the Cherokee). She listened, but didn't hear anything. Bummer.
I've had the plane for just over 3 weeks and have 29.1 hours in it so far. Life is good.
