So, I see this topic around randomly and most seem to agree that some sort of air flow to cool the ESC is necessary. My upcoming Dash 8 build will have this naturally due to intakes on the nacelles, but my V-Sliver and RETjet do not have any openings for air flow into the fuselage(by design, though they are a bit wonky after crash and repair) and they operate fine. The battery is warm but not hot and the ESC is cool by the time it's landed and I pop the hood. The V-Sliver will be rebuilt here soon, and I am wondering if I should add a small hood scoop to the design? It will definitely look cool, but will it improve performance or be necessary?
