Trim back to center, come in low, slow, nose high and give it power. Airfoil plotter view and plot a full size plan of the airfoil to your chord width. But if performance is an issue, as it is the case in contest flying, the airfoil should be carefully selected. Design, optimization, and construction of a high speed rc wing. Recently i saw a few 3d printed rc planes on the internet, since printing the plane body and parts is low cost and the pieces are replaceable it is a great choice to build a rc plane, but many of those planes had 3d printed parts as the base struc.

Common airfoils are designed and optimised for 2d flow conditions, wich just doesnt really apply in case of a delta wing. This airfoil was designed for speed wings too, but today you find even hlg tailless using this airfoil. Eh 1,59 for impellerturbine models with delta swept wings, acrobatics. The elilvon upper surface is parallel with the bottom surface of the wing which means that it also is reflexed. Sounds interesting but i have a few comments, with the prop in this location it will be very loud like a pusher wing and delta s have very short moments and it may be difficult to get the correct balance.
