Thanks for your encouraging comments Borsos, they are very much appreciated. I have the AeroClub Biplane Assembly Jig as well and have never needed it for a Wingnuts kit, for others it is almost always required. This "Third Hand" gadget appears to be the perfect tool for rigging, it's very flexible and once the model is properly mounted virtually any position can be set in seconds, I think it's going to be a real addition to the bag of tricks!
Cheers,
Lance
