Help with fueling up airplanes with cowl
I am new to r/c airplanes, with only one year of flying a trainer under my belt. Over the winter I picked up a few used glow engine planes that have cowls. For the life of me I can't see how the previous owner filled them with fuel. I'm used to pulling the fuel line off the carborator and disconnect fuel line from the muffler.
Both of the new planes have cowls with no way of easily getting t the fuel lines. Any suggestions on what to use and how to set the up to be fueled?
