Yes I do have the 6° stop, but have not installed as yet. To many issues to correct first lol. As you noted going there(6° stop) requires every bit of torque that engine can muster and a pump that is making all the flow it can. I have the engine about right now, but the pump pintle lever is not taking the swash plate to max angle because the forward throttle cable is too short.
You are right, the on off solenoid does not have a magnetic flux path that is conducive to power stepping response. The combination of spring rate, hydraulic force and orificing can dampen the swash plate movement between high and low motor speed(old school propotional response) but my calculations show this to be most unlikely with the motor components, the orifice sizing and length are not possible without a reduction hydraulic force area. So I have abandoned that effort.
Been eyeing up a 7° or 8° stop as well, but keep me posted on your proportional effort, that has real promise if can be done! Controller logic and a ramp able current may be tough to get, but that's the ticket.
Thanks for all your help Interceptor!
