Hi, On summer vacation seeing family for first time in 4 years.  I was planning to look for my boomerang which should e in storage for last 25 years.   So far no luck.  But my brother gave me his old Madcap. Here are some photos before I start dissecting and refurbishing her. anyone know if these controllers have any value on the second hand market? Quite dusty i think I can find better solution to the pins old school manual speed controller with 2nd servo sep
