RE: DC-3/C-47 question
I only know hearsay and dont know anybody personally that has used one. But they say it works. I guess I would try it out on a beater plane first. I've also heard the header tank works too. There is a guy on rcu called twinman that has done it. I've met him a time or two at swapmeets to talk about this kind of stuff. If you post it, I'll bet he responds. He's done a lot of experiments with different fuel tank setups in multi-engine planes.
