I flip my 1/4 scale gas planes over to defuel simply because immediately after defueling, I can then take off the wing. I usually defuel only when I am done flying the plane and ready to head home. If I need to defuel it for any other reason, I defuel through the T dot.

Also, using the felt clunks, I can't actually get all the fuel out of the tank, but using the vent line will pull every drop out.
