Minny, In the early and mid sixties we used silkspan and dope. I don't think monocote and such were even on the drawing board yet. All we could get in Newfoundland was 60 foot lines (.015) so that's what we used. I remember playing sick and staying home from school one day. Of course by afternoon I was all better and went to the school yard with that plane just as school was letting out. I was flying that thing like there was no tomorrow and everybody got off their busses to watch. They applauded in mass after one of my wild flights including about 10 consecutive outside loops. I sure wish I could bring those days back!! Oh well, I guess I'll head to the field now and fly my new 27% Cap 232. Model Aviation is the bomb!
