To solve the problem would require extensive surgery around the large fuselage root fairing, having moved the incidence pin and reblending the fairing from leading to trailing edge. This seems alot of work with refinishing and painting the fuselage. The question is why doesn't this model glider manufacturer take the trouble to rig check his build before finishing the fuselage and wing root fairing ? The error was very easy to see if you took the trouble to view from 10m behind the glider. This does not see to be a "professionally " built job to me. Regards John.

The model in question is mine and you are correct, cut with a CNC router. This is the second ARF I have acquired from this north central European manufacturer of sailplanes that can be purchased in kit, ARC or ARF form. The first also had rigging issues but to a lesser extent which I corrected as best as possible without surgery and sold the model on.
But getting back to the Petrel. In addition to the wing incidence I had to correct the tail alignment and fine cracks are developing beneath the Oratex covering on the fuz around the nose and tail which I think is filler cracking. It is a real shame. The construction of the individual airframe components is good in terms of accuracy and craftmanship and the finishing not bad at all (yes there were the usual cosmetics to sort out including paint runs). But the rigging is dreadful.
As I'm still in full time employment and travel extensively for work building a vintage glider is not feasible for a few more years so I generally fly modern glass gliders. And while I would like another larger vintage glider in addition to the Petrel ARF options are limited. I will certain not go with another product from this particular company (the Petrel supplier).
Perhaps I should have searched for CW Petrel that someone would have been prepared to sell.

Thanks for the heads up, as it is my winter project to cover and paint.
I will put a rigging angles check as the first job, while it is still relatively easy to fix any problems.
