I am installing a Futaba receiver in a Top Flite B25J. The airplane comes with an antannae tube glued inside the fuse. The airplane is so large, if I used the antannae tube and the supplied antannae, it won't have any portion of it outside the airplane which worries me. What effect would lenghtening have on the reception?

Do not alter the length of your receiver antenna. Many R/C models have the receiver antenna contained completely within the airframe. If your airframe is made of carbon fiber or is of sheet metal, then you will have to run the antenna outside of the model to get good reception. If the model is wood, fiberglass, or foam, then you'll have no problems, because those materials are transparent to radio waves.

Thanks Bax,

Just wanted to make sure.
