This (attached) is an interesting read about the history of the Howard 500.
Then, the pilot talks about flying the Howard 500 from taxi, takeoff, climb, cruise, descent, approach, landing, and taxi.
I think you will find it useful.
Dave Cummins validated the flight model and provided pictures for the project. He also allowed Scott Thomas, our panel gauge builder, to fly it back from Oskosh in the left seat from cruise to intial descent.
He was instrumental in making this project right.
Have fun.
There's some videos on my site, one about takeoff and climbout. You might notice how busy the co-pilot is, how long it takes the pilot to go from idle to full throttle on the rollout, the potential icing of the right engine, etc. Scott took this video from the jump seat.
