Awesome info, I wanted to make sure when you guys say 3 large tanks we are talking about the same large. These are the 3 tank sizes I have I the Large robart and medium robart, the middle is the skymaster tanks. I understand about volume but it seems like three of the large would be a bit much. I thought about running two of the large and then two of either the skymaster tanks or smaller robart tanks for the brakes/canopy/speed brakes and gear doors. I dont know where I would put four of the large robart tanks but two will under the aft equipment tray just in front of the main full tank, I can put the smaller tanks in the fuse on the outside of the inlets pushed as far forward as possible. I think like some people are stating its all about volume, Aussiebart mentioned his issue was getting the air pushed out on the back side of the air cylinder have more than one valve would deff help this as well.... I will post some findings and do a few videos showing the setups and how they work when I get to the final setup, I have the gear out at the moment doing other things.
