The DA50 prop uses electric heating. The prop heating automatically adjusts to constant-on below -10. Interesting that this is different from the DA42 and 62.

Great question—icing awareness is especially important in a DA40, which lacks built-in de-icing. The first visual sign of ice will often appear on the wing’s leading edge, spinner, or along the canopy frame. Since the wing is white and composite, it can be hard to see early accumulation—especially in low light.

Many DA40 pilots use a strip of dark tape or vinyl on the wing's leading edge (within view of the cockpit) to help detect ice visually. At night, a flashlight angled across the surface can help reveal changes in texture or shine that signal ice buildup. Always treat any visible moisture near freezing as a cue to exit the conditions quickly.

Stay safe and always trust your gut when it comes to ice.

Just a guess, but maybe different on the twins due to engine position.
Allowing ice to build up on DA50 and then melting it means it will be thrown clear of the airframe. On a twin, some of the ice will impact the fuselage with considerable velocity. Composites don't like that kind of impact.
