Thanks Alan, no hurry I'll check back tomorrow but regarding the "rabbit ears" I have exactly what you have (as far as 2 Robart air tanks above the fuel cell).
The tray and formers are the ones supplied with the kit but not mentioned in the instructions.
The Airpower valve is sold by Dreamworks, I will call them tomorrow also for settings advice, but it sounds like you are saying the gear will move quickly so I can have a relatively short delay time.
