Big Jim built 4 Patternmasters. 1972,73,75,77. the 1977 is the 60 size that everyone became familiar with and Bob Baron won the nats with. ( I crashed the 75 ship in 1982 never change your mind in a maneuver)
Big Jim built 2 L J's i have Big Jims second LJ ST46 trike gear at home. I also have his original plans andfoam cutting templates.
the LJ has 3 brothers SJ= small jim 35size, LJ= large Jim 46, BJ= Big jim ST60 (this is the model that Windy used for his first of 5 top five finishes at the nats 82,3,4,5,6 a couple were all were front row planes) and the SPECTACULAR 900
Mike Rogers,Hank forbes and Bob Baron all built LJ's and SJ"s
Bob Barons 84 worlds plane was to have been the LJ46 with an FSR motor but at the practice sessions Mike Rogers and Bob Baron decided to fly the Avanti to second place. Big Jim always reminded Bob that if he woild have flown the LJ he would have won.
