Hello everyone.
We are designing a solar powered aircraft in our institute. The airfoil e421 appears to fine for us (from the lift curves, pitching moments and drag polars obtained in Javafoil). I want to be sure that this airfoil works good for low speeds (15 - 20 m/s). Is anyone having experience of this airfoil ?
