The Sparky-Jr is approximately 2/3 size of the original 32" model designed in 1940 by Ed Lidgard. The Sparky is a classic design, which was produced as a kit by Comet up until the 1960's and is recognizable by many rubber power enthusiasts. The Embryo adaptation by Tony Pailleron, has a 19 1/2" span with 50 sq. in. of wing area. It is true to the classic lines of the full size Sparky with the only deviation being a change to the cabin to meet the FAC requirement for a cabin with an volume of 1.25" x 1.5" x 3". Kit is complete with Japaneese tissue, prop and rubber motor.
