Well, my plane flew it's first flight today. I didn't fly it, but the person training me did to check it out and trim it.
I have a question though regarding draining the tank. I've noticed that it doesn't seem to drain fully using an electric pump. Is this normal? Will a pump always leave some fuel in the tank or is there a problem somewhere?

The plane flew great while in the air.

how much fuel is left?

Not a whole lot, 1/8 of a tank?

It should drain better than that. But if you are actively flying (every week or two) just disconnect the fuel lines from the engine and connect them together if you can with a short piece of brass tubing so the tank is air tight.

I usually tilt the plane so the fuel runs to one of the back corners of the tank, and the clunk should go there as well to pump it out. The clunk will probably not reach all the way to the corner, so I usually rock it back and forth so the fuel goes to/from that back corner, and passes by the clunk. I can usually get all but a teaspoon or so out that way. I also drain or pump the fuel out of the carb/remote needle valve fuel line (if you have one).

TEH easiest and best way is to disconnec the tank and carb and use a short piece of brass tubing to connect the two ends.
