God must love rc flyers. I was on e-bay and found my plane. After 3 years . I sent the guy a message and he looked on the instructions and it said 2 and 13/16 from leading edge. See RCers are good as thay come. The kit sold for $170.85 . Heck I must have gotten a good deal on mine. It was built with a new rossi 60 engine and clouth covering for only $40.00. The old man just likes to build them then he flyes them once and starts over . I guess that is why I have 36 planes.....lol PS... Thanks for all the help.....
