Prop vs Turbine Race

[iamserow225]

Since your full-size vehicle has a variable-pitch prop, would it possible to in effect make it a 'turbine-mode' vehicle from v=0 to v=Vwind by making the prop pitch angle negative, and then transitioning to the existing positive prop angle 'prop-mode' vehicle to accelerate from there on?

Also, I was wondering if there was a way to calculate the optimum prop angle at any given point in the run (based on apparent wind?), or set up some sort of mechanical feedback system to do it automatically?

As a point, given prop blast (blowing a telltale backwards), might it not make sense to put a telltale on the FRONT of the cart?

We think it makes more sense to keep the telltale well off to the side so it's not in the path of the prop at all.

You go guys....this is fabulous stuff. Yes, a bit better recording would be great...but still good stuff.
