I really need help with this one. I have an UCD3D 60 with a Tower Hobbies 75 in the nose. the problem I have is that I noticed that when I fill the tank fuel starts dripping from the carburetor, I tried a different engine with the same results. I'm fueling the ting using a Great Planes Filler with a three-line ste up (engine, filler and vent). I was told that probably it was caused because the tank is too high in relation to the engine, but being an ARF there is no much you can do about it. What is the problem? [:@][:'(][&o]
