Geez, when I was a kid, most of us just hacked the block of wood into some kind of angle and tried to get the weight right! Mine are from '79-'80 or so. You'll notice that #8 has decals from a '50s model kit. My dad contributed to that one more, and our scale was off, which is why he drilled all the exhaust ports in it. We had to tape weights all over it at the race. It was awful, and didn't win anything. I did the purple one pretty much on my own. It was lopsided, and I brush painted it with airplane dope. I can still remember how strong the fumes were. Managed to pull out a fourth place with that ugly thing. I don't know if my son is going to do Scouts or not, but these pictures do seem like fun!
