Hi,

I'm building a jet for a guy, and he is providing the valves for the gear and brakes. I favor mechanical valves but, alas, it's his jet and he has provided the FEJ valve. I'm not familiar with this valve, but I think he also has the AP one. Is there one that's preferable? If so, why? Also, I have never used festos for air systems. Are people having good luck with setups utilizing festos throughout? The lines and fitting seem far heavier than Robart tubing and tees, but...

Thanks in advance for any insight.
