Interesting.  I bought the kit used, that may be the problem.  Plans show copyright date of 1973, but that may simply have never been updated.  Perhaps the one I built in 83 had the booklet and that’s why I don’t recall being puzzled by this

One of the planes in my stable is the Sig Akrobat which is very similar to the Chipmunk in size and proportions. My plane is covered with Monocote and weighs 46oz ready to fly. It is powered with an OS LA46 11x5 prop, 61' .015 lines eyelet to eyelet. I did have to add about 1.25 oz of tail weight to the rudder to get her to turn with authority. My plane likes to turn outside better than inside.Getting the full pattern out of it is no sweat I did use a plastic tank with muffler pressure. Enjoy your Chipmunk. PhillySkip
