# Impact to lift curve slope for a tapered wing with only trailing edge sweep?

I'd like to use a tapered wing with 0 deg leading edge sweep and 12 deg trailing edge sweep as shown below for my RC model. I understand that lift curve slope, a, is reduced for wings with leading-edge sweep since the normal velocity component is lower than the freestream velocity, resulting in a lower pressure difference between the upper and lower wing surface.

Would there be a reduction in lift curve slope or any other performance (compared to a straight wing, with no sweep), for my wing with only sweep at the trailing edge?

• Since we are talking about an RC model, the different Reynolds number between tip and root might have a not negligible impact. Plus all what @Koyovis has already explained. Feb 4, 2023 at 11:49

1. Lift curve slope. Leading/trailing edge edge sweeps of 0° & 12° yield a quarter chord sweep of 3°, which is very little. When for instance using the simple sweep theory like in this answer, wing lift coefficient $$C_L = c_l \cdot$$(cos$$\Lambda)^2$$ reduces by (cos 3°)$$^2$$ = 0.997 = 0.3%.
