Yes, Woody did build a balanced 3/2 FP valve. There are 2 in use. 1 in Tough As Nails (since 2002) and one in Woodies own machine KaPut.

Also, I have rebuilded in the past a LP 5/2 valve to be used @ FP. That went from solenoid activated to RC servo steered.
Woody improved that idea and now we have the grand total of 4 5/2 valves that can control FP with the solenoid.

Unfortunatly, all of those need LP to be activated.
