Conversation Between imsofaman and tsmithh

I bought what looks to be a PCA-2 Pitcairne from a fellow who said he built it years ago from plans (so long ago he couldn't remember the model name). It is a 3-blade design . Has a magnum .91 4-stroke. He said it hadn't flown yet. I found your thread and see that for a time you were selling producing /short kits. I was looking for someone to share pictures of this model with to help me figure out where to re-engineer areas that appear sketchy to me (mainly with the rotor). As far as proper CG position I understand that is determined by hanging the model from the rotor shaft then shift equipment until the model points nose down (to what degree I'm still trying to nail that down). Hope you can help. Thanks.
