TOPIC: How do you check the incidence of each wing.

How do you check the incidence of each wing. 3 years 2 months ago #1461

The only people more amazed than me that this aircraft is ready to fly are my children, who have grown up and left home since I started this project. Before I organise a trailer to take it to the airfield I want to check the angle of each wing relative to each other. As the original reference blocks have been removed some twenty years ago, can anyone advise me how I should do this. I intend using an app on my phone, but am not sure what position I should be measuring from. Any ideas ?

Paul Buckley has kindly come to the rescue and has answered the question. It has however raised another. I have about half a degree of positive incidence compared to the main wing. Is this sufficient for happy flying?

Jay Scheeval published the aerodynamic study of the Q2 variants here.

That should have enough info to keep you busy for a while.

You should be in good shape. The original Q-200 prototype with the LS-1 Canard actually had the canard with a positive 1 degree positive canard incidence relative to the wing (when compared to plans). Yours is within 1/2 degree of that. In my study, you will find Mike Dwyer's airplane is the closest that I have found in regards to matching the prototype, and his plane has been flying to his satisfaction for a few decades now.
