Nice neat layout. There are a couple of things to watch for... the first being the tight radius bends on the tubing when it exits the festo fittings. If the tubing does not enter the fitting straight and square, the little O rings inside can leak (I've seen this happen). Secondly, I don't see a FOD screen, but make sure you have one! You would be surprised how much "stuff" that big airscoop can suck up! And if you ever have a gear failure, there is going to be a lot of debris going through that inlet (trust me on that !
)
