[quote]QUOTE: Originally posted by Modelcar jhhtrainsplanes....Interesting photo in your profile... [/quote] The white part is actually an antenna. It is the verticle leading edge, VLE. If you look real close you will see a black box (actually 2 but one is on the opposite side) on the level part of the fuselage. These are called HF couplers. The VLE is screw/bolted to a connection on the HFs. What I was doing way UP there is taking out a whole bunch of screws so the VLE would come off. We have to add wiring all the way up to the "Boat" (the top of the tail cap area is the boat) so the VLE must come off. There are a TON of screw to remove and some bolts in very hard to get to places. I am hooked to an inertia reel (hard to tell unless you look real hard) to keep me from falling. As a guy you don't want to test the system (because of the way the harness fits) if you catch my drift. lol (but not lol if you have to use it) Something else FYI. I know inquiring minds want to know. On the news, after a plane crash, they always talk about the black boxes. Funny thing a black box is a t/r -- transmitter/receiver. The so called black boxes are not black, they are orange. They do not receive only transmit. Then only if triggered by an impact switch. They might have been black at one time but are not so now. Just a little info for the what is it worth area. lol
