Pre-Convention news: Sat. 4-5-2008 BPR flat track. I snapped some photos of Paul Sterrett's new "Classic" F1 car. This '64 BRM (practice body) is powered by ?????
A Pittman 196B!!!! I wonder if it is slow? The 196B is rated at 8V, so maybe running at 12+Volts may not be slow?
1.050" X .500" rear tires, .950 X .350" front tires, Stock Pittman 196B.
This chassis is a prototype of the upcoming D3 "Classic" F1 class (which is not official yet). As long as you use a Pittman 196B motor and correct tires sizes, you can be creative with the chassis.
This new class (if/when it becomes official) emphasizes a more scale class using a pre-can era motor. Front suspension features can help garner a better concours finish!
The tire sizes are more scale like than other D3 classes. Emphasis on scale features is encouraged (struts, A arms). D3 "Classic" F1 class gives equal points for concours and race finish.
Paul has incorporated more recent in-line chassis design with old motor type and wheel dimensions. Chassis design is left to the builder. Old technology with new design ideas can be fun!
An approach to simulating the front A arms is shown in this view.
Piano wire, brass plate and Pittman motors, a mix of old and new.
Stock Pittman motors require a very narrow crown gear to fit the narrow rear axle opening. It will be interesting to see what setup others bring to the convention. By the way, Paul was turning 6.3's on the flat track, so many of us may see only the rear of Paul's car during the race! Don't let the lap time bother you, let's have fun racing our 196B's!!
