I still have the Rubber Ducky and it seems to work just fine. I'm sure it has a shorter range than the stock antenna but still well beyond the range of my old eyes.
I haven't been very active in RC this summer. I have too many toys to play with. When the weather got warm in the spring the RC toys took a back shelf to golf and club building and golf forums. I also have a houseboat on a lake so there go the weekends.
Just yesterday I started cleaning my benches off to get back into the airplanes. I just happened to stumble across your email. The bad thing about not being active on the RC forums is that it takes me quite awhile to get caught back up current trends and equipment.
