Trainers
One of the reasons I bring this up a lot, it that I was in the same position once. Recently out of the service, married with a baby, and little income.
But I HAD to fly!
I was 3000 mi away from the rest of my family (so no access to dad's stuff) and I found a 2-channel Futaba radio in a pawn shop. This was my first Futaba radio - Talk about a "step DOWN"! In those days, if you came to the field with anything but the industry standard [Kraft] you were laughed at!
Imagine... buying a JAPANESE RADIO!
I then scratch built a small sailplane, and had a ball with it.
It was years before I had the time and money to get back into it full swing.
But I still had lots of fun in the meantime!
