How do UP2/UP3 Air Valves Work?
Just curious, how exactly do UP2 & UP3 Retract/Door Sequencing Air Valves work, I mean one servo, flip the retract switch on your transmitter and the UP2/3 Valves does the rest, opens the gear door then a short delay and the Gear extends; and on the P-51, the door closes after the gear is fully extended? what gives?
