Hey, I'm building a FEJ Rafale. It is the first plane I have had where I have had to plum lines for gear doors and brakes. I installed the 2 air tanks that came with the kit. I am planning on installing one air fill valve and one air gauge for entire system wich includes retracts, gear doors, and brakes. Is this ok to do, or should I install and plum in 2 air fill valves and gauges, one set for each air tank??? Not sure how is best to approach setup for air systems. Any suggestions would be appreciated. Thanks Jon
