Justin Posted March 11, 2023 Posted March 11, 2023 Hello, Well, there was little response to my ground attitude question. However, I had modeled the Q2 with standard gear and the canard jigging templates produced an anhedral of 6 degrees. This put the ground attitude at 11 degrees pitch. Somewhere I read it should be between 7.5 and 8 degrees, but almost all photos show that the pilot has a better view on the ground than the standard design really makes. Also, many photos show that people have considerably lowered the tailwheel. In the attached CAD STP file I have reduced the canard anhedral to 5 degrees. I have not lowered the tailwheel yet, but it should lower by 3.5 inches. Using a UL260i engine with a 48 inch diameter propeller, and allowing for 2" of strain in the canard and a loaded tyre radius, these changes still give propeller to ground clearance of 16.6" and a ground pitch angle of 8 degrees. Cheers, Justin STEP-Q2-Assy2023-03-11.zip 2 1 Quote

Justin Posted April 7, 2023 Author Posted April 7, 2023 I found the reference to the ground attitude in one of the newsletters.... https://www.quickheads.com/index.php?option=com_content&view=article&id=455:quickie-newsletter-25-page-9&catid=13&Itemid=110 Quote
