When I was a young lady my dad and I would fly and build planes, helicopters and yes we used to play with the old Cox cars. Anyone remember the Cox cars? My building experience is with when you had to use Dope on the wings and carefully lay the paper etc down, then I have used the stuff you put on loosely and use your hair dryer to stretch it. I have one plane that we never got around to building and I'm slowing making a place for me to start building it. Lots of fun but can be a very expensive hobby. I have one boat my dad built it runs off a steam engine, it is a fishing trawler. Nice boat, but I don't remember how to operate it, You have to use alcohol and get the water boiling for the steam but if you don't know what your doing you could blow it up and get hurt so it just sits on the shelf. I have taken it to the hobby shop in Marietta, Ga and the guy said he wouldn't touch it, never seen one like it, It came from Germany. We had a nice German U-boat with 3 screws, but it just sat and I gave it to a young man to enjoy. Thanks for the memories, fun times
