Its about a quarter inch to long and thats why I ask about it here I though something cant be right here with the kit being from great plane usally there kits are pretty good and instruction are very good!!!
I have calculated you chord to be 8.697 inches. I do not have the drawings.
Make it 8.75 ; the difference is only 53 thou ( 53 / 1000 of an inch ).
Your chord is about 1/4'' too long. That is 250 / 1000 of an inch.
What is your actual chord on the drawings?
What is your chord measured on the wing assembly ?
What is the distance measured on the jigs ?
I know you assembled the wing over the drawing but please make actual measurements.
I am just puzzled and interested if you do not mind.
Perhaps they have put in the kit jigs for another model by packaging error .

I checked the cord and it is right about 9" the opening on the jig is about 8 7/8" so i notched the jig to fit. I also checked the number on the piece of stock it came out of to make sure it was for the pt-20 and it is correct. Strange that no one else has run into this with this model.
