RE: To avoid disaster... check your fuel tank seal regularly!
I just took my UCANDO3D out for the firs time tis year last weekend and had a perfect flight. No problems at all. After the flight I noticed that it was real wet under the cowl. I have a Saito 100 in my 60 size one and the Saito has a vent nipple ont he crak case so I figured it must have had excess oil in the the engine. I got to looking and it couldn't have had that much. Turns out my tank leaked around the stopper and got the inside of the fuse wet a little and luckily most just got the engine and cowl wet inside. Easily cleaned up. The stopper shrunk back since the end of November and it is teh stock GP tank. The stopper was a loose and I had it tight. Very tight.
Always check things like this if it has si up a while. It pays too. a lot less work to pull the tank then to pull the tank and clean everythign up and I was luck not to have a fuse full of fuel. Balsa and fuel just love each other[:-]
