I've almost finished with my first airplane and could use a little advice. I built r/c cars and boats in the 80's, but this is my first plane. I went with the arf kadet lt-40 and was very impressed with the ease of assembly and the overall quality of build. My engine choice was an os 46ax. Here lies question number 1. Is it a terrible thing to use a fill line as well as vent and feed on my fuel tank? The 46ax has the needle valve on the back of the motor so my fuel line is about an inch long. This is a pain to take off to fill the tank. Can I fill the tank through the line between the carb and valve? (doubtful. but it never hurts to ask..)
My next question is the location of my rx antenna. Is it best to run under the plane like the book says or on top from behind the wings up to the tail?
Any help would be greatly appreciated. I hope to break-in engine thursday night. With good weather, my buddy (cert. instructor) & I can fly this thing on Saturday...
