HI WOULD LOVE your thoughts on the use of down and right thrust to improve the trim characteristics of an airframe- please only reply if you are very experienced , flying AND TRIMMING for many years
i have been building ,flying and trimming for 20 years-i have always set my wing , stab and engine at zero degrees to each other on all my airframes on jigs in my shop-my stuff flys on rails
i posted this in the 3D section and now the pattern section always looking to improve what i am doing in any way i can ENJOY REGARDS TONY
Hmm... on ALL you airframes?!
On a high-wing design with a flat-bottom airfoil? On a motor glider, some of which have 10 degrees down thrust?
Try 0-0-0 on the one pictured below - my aerial camera platform - and you will not get off the ground!
The motor thrust is set at 2.5 degrees of right thrust and 4.5 degrees of UP thrust, about -1 deg on the stab. It flies as if the motor were in the nose.
