Not particularly relevant, but on the subject of using the aux tanks I found out several years ago that it's a good idea to stay in balanced flight when near the end of the aux tank feed. I was finishing up a bird survey and nearing the end of the hour on the rear aux tank (had already switched the front back to the main-I stagger them by 5 mins) when the scientist with me asked if I could "do that forward slip thing" so she could take some pics out of the left hand photo port.

As soon as I rolled the plane and fed in opposite rudder, the rear engine let me know it wasn't happy...and neither was my scientist observer!

You mean you can't make any turns while on aux tanks? :-)

rmorris is an unknown quantity at this point
climb,climb,climb

as an interesting note, and you can try this out for yourself up at a safe altitude....if your aux tanks are low (not sure at which point exactly, but let's say half or less in them) and you are in descent, they will 'unport' and its as if you've run out of gas. But you can climb on low aux tanks all you like.

don't ask me how I know all this for sure, but just know it will be an uncomfortable moment if you are in descent for landing and suddenly your engine shuts off because you forgot to switch back to mains as part of the landing checklist....especially if it happens to you more than once
