The Bobcat's design was initially claimed to make FOD screens unnecessary, but that proved inaccurate (I know, since I Fodded my P120 in it years ago).

I haven't specifically tried the Tamjets FOD screen with a P70, but I do know that when I looked around at the time, none the commercially available FOD screens would fit with a P120 due to the way the CF deflection plates are positioned on the Bobcat. I had to use a home-made design that has concave sides on the strainer rather than convex.

Since the P70 is smaller, it may sit high enough that it can clear the deflector plates.
