Although Len has been very successful throughout his F3C competitive career, he is also as much a modeler as he is a pilot. He enjoys developing his own fuselages and specialty parts for his models. Len does all of his own building, modification, painting, and setup on his models. "I just would not get the same enjoyment out of the hobby if I did not build the models I am flying," said Sabato. "My interest in RC Helicopters started at the age of 5 when my father (Len Sr.) designed and developed his first helicopter, a fixed-pitch RC Jet Ranger way back in 1971." The model was manufactured during 1972 and 1973 under the brand name "RC Helicopters Inc.," and the prototype model is on permanent display at the AMA National Aero Modeling Museum.

Len states, "The pinnacle of my flying career to date was making the 2003 USA F3C Worlds team! I had been working towards this goal actively since my return to contest flying in 1998, and had been dreaming about making the team since the late 1980's. Making the team and being able to compete at the World Championships was at the very least a once in a lifetime experience that I will never forget."

Len is currently preparing 3 identical Vigor CS Heli's to complete with his own design "Eclipse" fuselages with retractable landing skids for the 2004 F3C contest season, and with some luck, a spot on the 2005 USA F3C Team for the next World Championships in Spain.
