DDWFTTW for hours on end

We got off a full weekend of dyno testing.

** Full range of speeds (up to 140% of design)

** Full range of AOA (from zero tip to 20+ tip)

** Full range of HP input (up to 2x design).

No runs, drips or errors.

Are we 100% happy? -- that never happens - especially with a limited budget, but we're feeling very good about being ready for the trip to Ivanpah.

From what we learned on the dyno we'll finalize our chain drive system. Additionally we're going from the weight saving aluminum axles to steel. We came to suspect that the aluminum versions weren't going to hold up as well as we were told they would. Don't want to risk a break of an axle in the desert. Steering linkages and brakes will be my focus the next few evenings.

The very good news from this dyno round was that again, at every AOA, and every RPM (within the limits of our motor of course) we were pulling forward with enthusiasm.
