I have to agree! Never been any place but Firebird Raceway in Phoenix... but that brought many of the "big dogs" out!
Imagine a fuel dragster trying to hook up with a prop, a couple fins, and a rudder! Gets pretty wild, and they can't just bounce off of the guardrail!
After about 35 years away, I got back into the model building of my youth. One of the first things I did was get blueprints from one of the major hydro companies, then built some scale model kits complete with capsule, rudder, and V-drive!
Here are pictures of a couple I built from the kits. Of course I had to throw in some custom paint too! :-)~ After that are some that friends built, and the raw kit.
