I would like to know if anyone has installed a Transponder in a Cub with no electric system? How do you do this? Can you have Altitude Encoders available on these units? Where do you mount the 12 volt Battery? How do you install the system to make it look like a Stock Cub? I hope this really starts a good discushion on this subject!! Thanks, Papa Bear
