Greetings Fellows,I'm going to copy my question from the GN-1 list to you; I hope that, in the spiritof scratch building, you all won't take offense at having a GN-1 questionposted to this list. Thanks, to all as ever, for your help.AlanGents:I've been following a thread on the Piet list concerning the length of cabane strutson the Pietenpol. In a sample response from builders, all front strutswere taller than the rear-averaging 23" front and 22" rear. Our GN-1 plans callfor 23 1/4" fronts, and 23 1/2" rears. Are you fellows using these plans dimensions(are they accurate?) or have you altered the lengths of the cabanes?Alan LyscarsPortland, Maine________________________________________________________________________________

don't do the GN-1 to the plans lest you will fly tail low. Set your wing so thatyou have a 1.8=B0 AOI. The plans put the wing at an angle quite a bit lessthan that. ----- Original Message -----

Thanks, Dale, for your response. I'm purdy sure, however, that those dimensionsare the cabane spacing, center-to-center, of the cabanes as attached to thefuselage.Alan ----- Original Message -----

Thank you DJ. What do you reccommend for cabane dimensions?Sincerely,Alan ----- Original Message -----

my dimensions will not be accurate for your application. I have modified my wingcenter section spar plates due to me lengthening and widening my fuselage.just strike a line from the center of the radius on the leading edge to the centerof the trailing edge point and set that line to 1.8=B0 or so and that willbe your AOI (angle of incidence)DJ ----- Original Message -----

Alen I have plans for the GN 1 but I built a Pietenpol. I notice that the GN 1 fliestail low. It just does not look right. Dale----- Original Message -----
