I have a set of unused plans for the GP Goldberg Chipmunk that you are welcome to have. They are from a kit I just bought so they should be up to date.

Dave is correct there are some ribs that need to be orientated in the correct position. However if you are going to put the servos in the wing (recommended) and/or are not going to use flaps it really doesn't matter.

Good luck on your Chipmunk and if you are interested in the plans let me know.
