- If you want to see evidence of a deployed chute spike, ask Turk for his Maxton QwikData files. Print the histograms for his front and rear potentiometers. The spike is quite evident. John Goodman ___

- Hey! I never thought of that. I have the data and there is a monsterous spike right before shutdown. And that is in a car at only 200 mph and a short tow line. A bagged stroud chute might work better

- Were back to understanding the forces at work here. I think you could put 5 turns of standard (cheep) duct tape on the shroud lines and it would slow the opening by 200 - 400 milliseconds. They tried
