Thanks for the great feed back.
I am already designing panel 2.0 version.
I found after the first mock up i had a little more wiggle room than i thought.
I hope to have a new version cut out this weekend and post a picture.
It will have the 5 round instruments plus a small fuel gauge on the right,
and the fly pad mount as close to that stack of instruments as possible.
I have not determined if i will be installing a transponder yet, as i don't plan on flying in controlled air space.
I do plan on setting aside panel space for one in case i want to add it later.
I will be using a handheld portable radio which i will surface mount to panel beside flypad mount.
Switches and circuit breakers will be under Flypad mount just left of center line of panel.
I am looking for a supply for good quality single pole toggle switches around 1" tall to fit my panel.
