Here is a fun aircraft of the month, the Starr Bumble Bee was designed with the whole intent at beating the title of the worlds smallest maned aircraft. It was designed by Robert Starr from Arizona, and first flew in 1984, he followed this up with the Bumble Bee 2 that was even smaller and lighter that first flew in 1988. On May 8th of the same year the bumble bee 2 had a down wind engine failure resulting in a crash, Robert was injured but made a recovery.
If your in the Tucson area they have the surviving Bumble Bee 1 aircraft on display at the Pima Air & Space Museum
6000 E Valencia Rd, Tucson, AZ 85756
with its compact simple form its a popular RC model.
For those interested in RC scratch building Outerzone has one designed by Ken Willard who has several RC plans on the web site.
