I assume you're describing a flop-tube type of inverted fuel pickup. My airplane has a header tank- can you describe how that works?On the inverted oil system, am I right in saying that you've described the Christen inverted system? Also, one addition to the system that I've heard of is a swinging oil pickup. Is the purpose of the swinging pick to allow oil flow during knife-edge flight? If so, how does that work out if the ball valve is not seated at either end?
Thanks in advance.
