I am only loosing pressure when i turn on my radio. If the model sits with wheels down and radio off I can pressure up tp 100psi and it holds that presure but as soon as I turn on my radio the pressure drops to about 80psi and then stabalizes.


I had only one medium size air tank for the gear & doors & got the same drop in pressure as you, when I switched on the radio. I think the reason was, the lines & all the cylinders get pressurised at switch on & with the gear cylinders being large, they consume a lot of air. I fitted an additional large air tank, so now have two tanks of air & there is no drop in pressure.
